Sing Door Ship Receive Warp-free Care

Shipping, Receiving, and Care of

Your Warp-free Sing Door

Sing Core only works with the best and most highly proficient millworks and door manufacturers. This segment of the industry is well-versed in how to deal with high-end building materials such as Sing Core. For many years, Sing Core has provided unfailing warp-free solutions to the biggest and best architects and millworks in the world, without one complaint.

As more millworks and smaller door companies are reaching out to offer their clients access to Sing Core, we do occasionally run across industry professionals who are not aware about what to expect or how to handle Sing Core raw materials. Some of these less-experienced, newer and/or smaller millworks and door companies may not know what to expect when dealing with a product like patented Sing Core. We desire to welcome newcomers to have access to patented Sing products. For those, we are providing the following information:

Unfinished

All Sing products are shipped as unfinished to the millworks and door companies who are highly proficient in working with high-end materials such as Sing Core. A Sing door blank is not a ready-to-install door and are not available from the factory with hardware or as pre-hung doors. Sing Core works in tandem with the industry professionals and the factory may, or may not, handle some of the detail works, such as applying exterior skins to the door blank. The door finishing, hardware, framing, and installation are all coordinated before your Sing door blank is built.

Packaging and Shipping

Sing products tend to be very large in size and require custom crating to assure they are not damaged in shipment to the industry professionals. Even with the best efforts of Sing Core’s custom crating team, sometimes a Sing product may arrive blemished and/or damaged by the shippers entrusted with the handling of crated Sing materials. In most, if not all, cases the level of structural integrity of Sing products in combination with the high level of proficiency of the finishers receiving Sing products, even damaged Sing Core can easily be returned to new condition, even if mishandled or damaged in shipment.

Arrival of Sing Products

Upon arrival of Sing products, be prepared to receive an unfinished product via truck. Offloading may require a forklift and dock for receipt. That said, there will be work that needs to be done to the product received by the millwork or door company before it is retail-ready.

Acclimatization

In most cases, when receiving a multiple Sing Core order, where Sing door blanks have been shipped in a stack, or side by side, it is perfectly normal for even a warp-free door blank to appear to be warped upon receipt. Usually, the Sing door blank(s) which face the outside of the crate, or the top of a stack of warp-free door blanks will appear to be warped. By acclimatizing these doors, they will straighten out to their straight and true flat appearance.

To acclimatize your Sing door core, stand your door on its edge at least twelve inches away from any adjoining surface area, allowing it to acclimate for up to 72 hours. Measure your door again and you will find it to be straight and true. If not, document for warp and contact Sing Core.

Panels must be sealed or painted before being hung to prevent warp.

Panels must be protected from weather exposure with overhang, sealing, or cladding to prevent warp.

Storage

After you’ve received your patented Sing products, in the event that you will have to store them prior to finishing and/or installation, try to store them standing upright, on end, with plenty of space in between. Do not lean Sing products against a wall. If you have to store them stacked, wrap in plastic and place one or two sheets of plywood underneath and on top of the stack of Sing products. This will help keep the entire stack similarly acclimatized while not in use, otherwise, you may have to re acclimatize the top and/or bottom Sing products later, when you are ready to use them.

Door Warp Definition

Door warp is a variation from a plane surface within the door itself. It does not refer to the door in relation to the frame or jamb in which it was hung. Bow, cup, and twist are terms which describe warp in a door and are defined as follows: Bow is a curvature along the door height, or a deviation from a flat plane from end to end. Cup is a curvature across the door width or a deviation from a flat plane from side to side. Twist is a distortion in which one corner is out of the plane of the other three corners. Warp is usually a result of unequal stresses within the door from one face to the other caused by changes in humidity and temperature conditions or uneven conditions from one face to the other. Buildings shall be humidity and temperature controlled before doors are delivered and installed. Required conditions are 25% to 55% relative humidity and 50° to 90° F (10° to 32° C) temperature range. Improper handling, stacking, and storage can also contribute to warp. Doors shall be stored flat on a level surface off the floor with cross supports.

HOW TO MEASURE WARP

Use a taut string or straight-edge and measure on the concave face of door – diagonally, horizontally, or vertically. Measure at the point of maximum distance between the taut string or straight-edge and the face of the door.

Measurement must be made on the concave face of the door. Door shall be open when measuring for warp (lock not latched into strike). One person can measure warp using a string and taping one or both ends onto the face of the door, holding it taut. Don’t measure warp in relationship to the door frame. Often a door may not fit into the frame properly but is not warped. In these cases, check the frame – it must be set plumb and square and jambs must not be twisted or out of alignment. Action on any claim for warp may be deferred for up to one year after project completion to permit doors to acclimate to temperature and humidity conditions.
 

ALLOWABLE WARP TOLERANCE
FOR WOOD DOORS

1-3/4 inch (44 mm) or thicker doors:

  • 3’-6” x 7’-0” (1050 mm x 2100 mm) or smaller, 1/4 inch (6.4 mm) maximum.
  • Larger than 3’-6” x 7’-0” (1050 mm x 2100 mm), 1/4 inch (6.4 mm) maximum in any 3’-6” x 7’-0” (1050 mm x 2100 mm) section.

1-3/8 inch (35 mm) doors:

  • 3’-0” x 7’-0” (900 mm x 2100 mm) or smaller, 1/4 inch (6.4 mm) maximum.
  • Larger sizes not addressed in this standard

Warp-free definition: Doors with patented professional SingCore inside outperform any other Eco-friendly door in the world in terms of being lightweight (SingCore weight is approximately 10 % of solid wood, timber or plywood core) and high strength (660 PSI+, stronger than steel pound-for-pound). No other door Eco-friendly door made in the USA can reach our high precision (SingCore approximately +/- .006 inch) or flatness meets or exceeds door industry allowance for door warp, as seen above). We guarantee no other Eco-friendly, lightweight, high-strength insulated door can compare with any door that has patented professional Sing Core inside. SingCore is raising the standard of what is possible in terms of building large doors that can be true flat and warp-free.

How can you tell if you have a warped door or not?

There is an industry standard method of determining whether your door is warped or not.

To determine whether you have a warped door or not you will need a length of string (longer than the length or height of your door) and a measuring stick or tape measure.

a) Tape one end of the string to the edge of the door and the other end to the opposite edge of the door.

The string should be straight. If there is a gap between the string and the door’s surface, you may have a warped door.

b) Measure the gap between the string and the door’s surface area.

If the gap is greater than ¼” your door is warped (according to AWI standards for 1-3/8 to 1-3/4 inch doors 3’-0” to 3′-6″ x 7’-0”).

c) If the length exceeds 7 ft. AWI standard applies to any 7 ft. section. Apply string to any 7 ft. span.

Contact your door maintenance company and send them two photos.

d) [1] Photo of the length of the string which shows as much of the door in its entirety, or at least from one end of the string to the other. Then [2] a closeup photo of your measurement of the gap.

Armed with these two photographs, which can easily be emailed to the millwork or door maintenance company of your choice, the recipients will be able to determine how best to approach the repair or replacement of your warped door.

You might consider replacing your warped door with a professional door which has Sing Core inside which can be guaranteed not to warp, bend twist or otherwise fail so as to avoid this pitfall in the future.

For more information, see: Door Warping vs. True Flat

What if my door with Sing Core inside is warped?

The same standard method of determining and measuring any door with Sing Core inside is used just like any other door (as noted above).

Contact Sing Core about your concerns about your door being certain to include the two photos as noted above.

If you have purchased a professional door with Sing Core inside, you may be the recipient of a replacement Sing door.

Note that upon arrival and un-crating of a door with Sing Core inside, a door may appear warped (and indeed it will be measurable). This is normal for a door which has been packed and in transit. Stand your door on its edge at least twelve inches away from any adjoining surface area, allowing it to acclimatize for up to 72 hours. Measure your door again and you will find it to be straight and true. If not, document for warp (as above) and contact Sing Core.

In the event that a professional door with Sing Core inside is warped (which is highly unlikely) your help in determining the cause of the door’s warping is appreciated. Please assist documenting the chain of custody of your professional door with Sing Core inside, including the millwork or door company which finished the door, and the installers who installed the door, to help us insure your replacement door remains warp-free.

Sing Core Definition of Terms

Acclimatization

Sing Core panels acclimatizing: According to the type of the skin. Aluminum, metal, plastic skin, concrete, and ceramic skin will be delivered in perfectly straight condition without any acclimatizing. Plywood, hardboard, and HPL will take much less time to acclimatize than MDF. The best way to acclimatize is stand panels on edge with 4” or more of equal spacing between each panel.

Eco-friendly

Contrarian Sing Core purports to introduce a new degree of Eco-friendliness in sustainable building materials, not expendable and disposable import products which dominate the present day architectural landscape. Sing Core is ecologically conscious throughout its Made in the USA manufacturing process. The factory expends very little energy, local manpower, to manufacture Sing Core which is built from the smart use of a combination of natural wood resources, insulation and formaldehyde-free adhesives in the non toxic manufacturing process of the sustainable lightweight and high strength building material designed to last for centuries.

Edges

Edges of Sing Panels can have a variety of options. They can be open-faced (no edges) which means the patented Sing core material would be exposed and visible from the edge, between the two surface materials (skins). Edges can be embedded and pre-sealed between the surface skins per specification. Standard edging is 1.25 inches solid wood. Edge-banding is commonly applied by millwork or other finishing agent.

Embedded Chases

Chases or channels for cable, electrical or other services (such as water) can be pre-installed to specifications during the manufacture of your Sing Panels. Contact your Architect or Sing Representative to make certain your embedded chases are manufactured to meet your needs or specifications in advance.

 

High Strength

Even though extremely light in weight compared to other lightweight honeycomb and/or substrates, patented Sing Core was independently tested for structure strength and rated at 660 PSI (which can achieve higher ratings, if necessary for your specs) making it stronger than steel pound for pound. Other lightweight materials have structure strength of 10 to 110 PSI. This is what gives patented Sing Core its stellar reputation for high strength with little or no deflection over long spans with little substructure.

Insulation

The otherwise left empty voids in traditional torsion box is filled with rigid insulation material which serves as rigid material which shores up the vertical grain torsion box walls imbuing patented Sing Core with its unparalleled structure strength, while adding insulation qualities of climate control (R-value) and sound deadening (STC-rating*) attributes. The insulation used inside the Sing Core torsion box structure grids can be altered to meet architectural specifications and/or performance expectations.

Internal Blocking

Internal blocking or solid implants can be strategically placed inside your Sing Panel or door blanks per your specifications. Please double-check your specs prior to having your Sing Panels or door blanks manufactured.

Large Door

Where Sing Core shines in the door industry is in the ability to provide a lightweight high-strength door blank to door manufacturers and millworks for doors over 7 ft. tall and 3.5 ft. wide that will not warp. Solving not only issues associated with door warp, but also minimizing the weight of large doors without compromising strength. How large can a door be with Sing Core inside? Sing Core can build large door blanks in nearly any size up to 50 ft. tall and/or 50 ft. wide, or more.

Lightweight

The average weight of a Sing panel is 1/2 pound to 2 pounds per square foot. Weight is determined by many factors including torsion box grid size, rigid insulation material and glue used as well as other components of the panel’s composition including patent pending professional warp-free stiffeners, surface materials (sins) and adhesives used in the manufacturing process. Your architect or Sing representative can present you with a projected weight estimate prior to manufacture.

Paint Grade

We deliver your panels as unfinished “paint grade” as opposed to paint ready. Under normal circumstances, Sing panels and door blanks are provided as paint grade to millworks and door manufacturers who prepare the surface area for paint if necessary or required. If you require paint ready Sing panels or door blanks be certain to specify expectations prior to manufacture.

Post and Beam

Post and beam is only represents the depiction of a specific dimensional characteristic of an otherwise normal Sing panel, where its dimensions dictate the proportions and function of it as a post or beam. When used as posts and/or beams, Sing Core offers unique advantages over traditional wood and/or metal posts and beams.

Professional Grade

Professional grade panels can be guaranteed warp-free for 50 years. Composite stiffener technology is integrated with the structural core, which prevents warping and provides a truly flat panel. Professional grade panels provide a 50-year non warp guarantee when used in appropriate applications.

RSIP

A Sing panel is classified as a Reinforced Structural Insulated Panel (RSIP) due to its underlying reinforced torsion box grids which is the heart and soul of patented Sing Core.
Sing Core

Patented Sing Core is the key to the success of Eco-friendly, lightweight, high-strength Sing products. The specifics of the design features small (2 inch to three inch) vertical wood grain torsion box grids where the voids (which would otherwise be left open) are filled wall to wall with rigid insulation material. This core material is sandwiched between two surface skins and may (or may not) be framed with wood or an alternate framing material inside the exterior stress skins.

Sing Panel

A Sing Panel consists of a substrate of patented Sing Core sandwiched between two stress skins of any available flat building material which may or may not feature exposed edges or closed (framed edges).

Size

The dimensions determining the size of any patented Sing product are determined by architectural specifications and include: length or height x width x thickness (in inches). These dimension are necessary for a preliminary price quote.

Skin

Skin refers to the flat building material that acts as the stress skin for completing the reinforced torsion box design. While the core supplies the vertical torsion box walls, the exterior stress skins seal the top and bottom of all interior boxes. Skins can be made of any flat building material including any available species of natural wood, aluminum, concrete, fiberglass/FRP, Kevlar, LVL, MDF, Metal, Steel, etc… These skins are adhered in an Eco-friendly manner using formaldehyde-free glue, cold pressed with very little energy expended and little no toxic fumes or unnecessary waste.

 

Storage and Protection

Store your Sing Core door in an upright position and allow to acclimate to room temperature following shipment receipt or prior to finishing or installation.

Strength of Sing Core

The strength depends on the thickness of the panel. For instance, if you double the thickness it will be 4 times the strength. The thickness of the skin could make up the extra strength but increasing the thickness to gain strength will result in added weight, which may compromise the end result. The answer is usually a combination of matching the right Sing Core width with the appropriate surface material to achieve the desired results without loss of structural integrity or unnecessary additional weight.

Structure Warranty

The structure warranty that accompanies professional grade or hot press ready grade Sing panels or door blanks warrants your Sing product against structure failure. Also ensures that your Sing products are not disposable, are reusable and can easily be repaired if damaged, often on site without disassembling using regular woodworking skills and tools.

Thickness

When Sing Core representatives reference the thickness of a Sing panel or door blank, it generally includes the thickness of the Sing Core insulated reinforced torsion box core, as well as the thickness of the exterior surface materials (skins) included.

 

Trade Professional

Sing Core only supplies their patented material to trade professionals, like architects, cabinet makers, millworks and door manufacturers. Sing Core does not offer materials for retail. If you are a home owner who desires to have Sing Core products incorporated in your home, contact your local trade professional (architect, contractor, builder, cabinet maker, manufacturer or door company) for more information. As you know, we do not ship finished materials and only ship to authorized finishing facilities (millworks) who are responsible for finishing your Sing products. These are the people that make us look so good.

Trimmed / Untrimmed

The default condition of Sing products is normally untrimmed. This means your sing products will arrive at your millwork or finisher with unfinished, untrimmed edges and exposed glue may be visible from the edges of the Sing panel or door blank. Alternatively, your Sing panels or door blanks can be trimmed by request, leaving a clean, smooth finish on the edges. Allow ¼ inch for trimming, if requested to be completed prior to shipping from Sing Core. Be certain to specify “trimmed” when ordering your Sing products, as they will have to be build oversized to allow for the ¼ trimming.

True Flat

True flat is what Sing clients have referred to Sing products as. It is not an industry term, but it did become common vernacular in reference to Sing products which outperform any known lightweight, structurally strong product in terms of flatness or lack of deflection under load and among long spans. True flat is considered proprietary nomenclature and does not have a scientific definition or industry-wide classification because nothing compares to Sing Core in terms of Eco-friendly, lightweight and high strength.

Turnaround Time

The standard turnaround time for Sing products is approximately four to eight weeks, so take this into consideration when you are ordering your Sing products. In a hurry? Check with your Sing representative, rush service may be available for an additional fee.

Unfinished

The standard condition for delivery of Sing products is, “Unfinished.” That is to say Sing products are not manufactured to be an end-sale product. Sing Core’s standard method of operation includes wholesaling and shipping Sing products to millworks, cabinet shops, finishers or door manufacturers who complete the process and ready the items for installation or resale. Sing products are not retail-ready and not available directly to consumers.

Warp-Free

Warp-free is the Sing Core promise for the condition of professional Sing panels which are built for specific purposes and high precision expectations. Professional grade Sing products are a concerted effort of the designers , architects and the True Flat team at Sign Core to create a Sing panel or door blank that will endure the environment and circumstances facing the regular use of said panel or door over a 50-year lifespan. A professional Sing panel built to these specifications and used for its prescribed conditions can be delivered wit an accompanied hard copy signed certificate insuring the product to be guaranteed to remain warp-free for 50 years.

Wood Stave

Wood staves (a narrow length of natural wood “stave” with a slightly beveled edge) can be utilized to form the exterior of Sing Core panels or door blanks. These can be used to replace other types of solid wood building materials. Natural wood stave species are subject to availability. Standard wood stave exterior measures 1/8 inch and is available in other thicknesses according to architectural design and specifications.

 

* Note: STC rating varies according to size, thickness, skin, and other factors. Sing Core does not rate doors, although we are fortunate enough to have one of the best sound testing labs in the world, here in the Pacific Northwest. If you require a specific STC rating, Sing Core can build a door to your architectural specifications and have the resulting door tested at our rating facility for an official rating.

Seattle’s Symphony of Architecture and Design Center for the State of Washington

sing pivot doors in center for architecture design seattle with man doorsGreen building materials are the focus point of every architecture design now-a-days. As the home of the architect and design community for State of Washington, which is the leader in high tech and advanced materials playground for searching the planet for green, earth-friendly products is essential for this new home for all designers and architects.

In the temple of Seattle’s Center for Architecture & Design, the evergreen state sets the standard for promoting the highest standards of preserving our green earth among the Pacific Northwest architectural community while seeking out new ways to approach a more sustainable approach with building products that save energy and add longevity to the overall life of projects around our local communities and the world.

The idea of a local design center is not new, but the Seattle design center is the leading edge of this new technological approach to new office designs; bringing to life the idea of a multi-functional design combining office space, media, meeting and a gallery to promote green design permeating all areas of life and our society.

It all starts with the composer / architect of the project; with Ric Peterson’s design of Suyama Peterson Deguchi, while leading the team of the designer of the total project which includes a varied line up of suppliers, general manufacturers and fabricators to tackle the most challenging job to represent the state’s finest architects and designers. When all is said and done, the resulting space in this center represents the new philosophy and concept of engineering for a better world within the office space that has superior functionality as it is easy to maintain and built with the longest lasting building materials.

The symphony’s composer is Ric Peterson, FAIA of Suyama Peterson Deguchi was charged with the challenge of creating a design center work of art. The score is conducted by general contractor / conductor of the symphony, Krekow Jennings supervising all components while acquiring and arranging the performers (trade professionals such as sub contractors) participating in the creation of the newest chapter in executing the design by using green building materials made locally, produced with less energy and waste used throughout this project. The resulting masterpiece is a modern office, meeting room and gallery in a picturesque downtown location as a perfect showcase for professional trades and an inviting exposure to the general public. The whole job will not happen if without all the support from the donor of their trade skill to help such as painters did all the paint work for the furniture, and Schuchart/Dow craftsmen did all the assembly which basically started from patented Sing Panels, all in flat-pack which is easy and takes up less space for shipping to the job site avoiding damage during transport, and the end result is a new chapter of this ornate symphony of building art; simple, functional and elegant.
huge extreme edge pivot doors in seattle center for architecture design sing core

FAIA Mr. Peterson is a senior architect for Suyama Peterson Deguchi (SPD) responsible for providing the solutions to build the multi-function 4800 sq. ft. space by creating a gallery that could be converted to a conference room within minutes to hold secure meetings within the center itself. It needs a special pivot door when it open it is a large gallery, when those 4 doors closed it become a conference room. All the furniture, work tables, islands and counter tops are quickly and easily assembled on site

About the large pivot door: Mr. Ric was able to accomplish the door solution by teaming up with inventor, Peter Sing, whose lightweight, high strength building material made it all possible without the use of heavy equipment, lifts and cranes. After being invited to join the project, Sing offered to supply not only the doors but almost the rest of all the office furniture, partitions and even part of the dining table/work table and cabinets in the lunge and office areas – all made of patented Sing panels, same core materials to build those 4 large pivot doors.

About the large pivot doors: There are four 12 ft. x 10 ft. x 5 inch thick doors, It starts with patented Sing core as door panel each weighing around 500 pounds each for easy moving as shown at above pic. Each door was installed in less than a half an hour. These unique large extreme edge pivot doors were manufactured in Washington state using patented Sing Core as the embedded structural core material. those door had added two more layers of material on the job site to create sound deadening and fire retardant features, Even with his lightweight, high strength core material, the wall feels as though it is made of solid stone, when you knock on it. Two of the doors feature a built in man door for simple access when the area is secured as a conference room. Four doors are easily 12 ft. x 10 ft. 2,000 pound pivot doors by the time completed provide the conversion from gallery to conference room quickly and easily.

About the furnishings, desks, tables and partition walls: Office area are also with totally new design approach with new leading edge patented lightweight , high strength eco friendly Sing panels. all those office furniture are assembly on the site by use patented Sing panels all flat pack after paint by painters and hand carry to the designer center, some shelf / table top and partition wall are over 12 ft. in length. Each of the panels are designed to be able to be carried by one person.

Assembling office furniture from sing modular panels lightweight high strength seattle center architecture designThe features of the office and lounge areas are simple but elegant in the functional execution of the artist’s design concept. All the furniture features adjustable legs to maintain work surfaces at high precision instrument grade levels. Up to 8 foot clear span work areas are neat and clean while keeping all power and other cords neatly hidden from view by an embedded wire management channel system that is an effective design component within the work areas. Single piece partitions that span up to 12 feet provide privacy and security while standing flawlessly amidst the efficiently accurate space.

Not resorting to raised level work areas provides an effective approach to cleaning and maintenance of the floor space that is both easy and saves time. all the wiring are hidden within the desk top and shelf channels, instead build raise floor as most commercial office space which takes more space and more assembly time and lose more precious space.

Completing the symphonic work, Sing and his patented product “Sing Core” is joining the team of suppliers that is bringing the dream of Seattle’s design symphony to life.

Hearing about this project might cause you to wonder how an entire facility of this magnitude could be quickly and easily assembled out of multiple integrated modular panels. This is the first time such a grandiose project has been built completely of lightweight high strength panels that are not only sound deadening but are resistant to warp, bend or twist, even while covering long spans and featuring natural wood surfaces.

Thanks to Sing’s lightweight material, it took less than 2 hours to unload and install those huge pivot doors (weighing-in at only 500 lbs.) and three craftsmen assembled and installed all the office and lounge components and furniture. Sing Core it the new Eco-friendly building material that has helped to create the strongest most lightweight office furniture ever invented in the world, creating endless possibilities to provide architects, engineers and designers the ability to provide sustainable long-life office furniture and so much more…

The advantage Sing office furniture which furnish almost the entire design center space

1 Easy to clean floors (less table legs shelf supports to interrupt the cleaning process).
2 Easy wiring management (all wires are hidden in the channel between the partition wall and desk top).
3 Some areas designed with clear span of 10 ft. plus (the shelf top and the table top are at same level) providing more working surface and elegant work space.
4 Partition walls are made of a single piece large panel (without joining to separate entire work station, offers more privacy yet simple, elegant and functional).
5 Easy to assemble on the job site (entire office lounge area constructed of Sing Panels (each piece of furniture is flat packed and installed by Schuchart/Dow).

The advantage of pivot door / partition wall

1 Change the conference room to gallery within minutes.
2 Fire proof and sound deadening patented Sing pivoted door.
3 Man door on both sides of the entrance for easy access.
4 The lightweight and strength of Sing pivot doors enabled designers to add 1,500 lbs. of additional material without compromise.

How to Attach Wood Planks to Sing Panels

Add-stiles-and-rails-to-your-sing-door-as-anchor-points-drawingSing Panels are so versatile, you can do just about anything with them.

As a matter of fact, prepare to adjust your thinking, because thanks to Sing Wood Planks you can,

Say Goodbye to Tongue and Groove

Tongue and groove joinery is designed to keep wood planks flat when attaching because wood moves. Natural wood (or most any wood product) tends to warp, bend or twist due to environmental changes.

Not necessary when using Sing Hardwood that is created true flat and will stay flat indefinitely.

What if you needed to attach wood or tongue and groove planks to the surface of your Sing Panel?

No problem.

Just make sure that you order your Sing Panel with the solid wood (or other material) implants to meet your requirements.

You can add stiles (vertical implants) or rails (horizontal implants) to have the anchor points that you need to match your expectations.

The only caveat, is that you must leave at least 12 inches of Sing Core material on either side of the implant in order not to compromise the sustained flatness of the lightweight, high-strength panel or door.

How to Build a True Flat Wood Door

10×12 ft 3″ thick warp-free 1/8″ oak 520 lbs

foam-panel-guaranteed-true-flat-lightweight-strong

True flat technology is based on expertise in building any door that can be guaranteed true flat and stay flat. This composite science includes the proper proportions of Sing Core, aluminum and/or other materials and bonding agents based on your requirements or specifications. In this way each Sing door is a work of art.

One of the challenges in building any wood product of any dimension where the customer desires a perfectly flat surface over long spans is insurmountable in many circumstances.

This is the proven niche specialty service provided by Sing Core to the worlds most high-end, demanding, high-profile millworks and end users for years. Due to the unique properties of the patented Sing Core material, true flat designs can come to life and deliver superior satisfaction while carrying a 10 year structural guarantee.

AWI standards may allow for a certain amount of deflection over long spans, the patented Sing Core material far exceeds deflection allowances of other materials, due to its torsion box design while remaining true flat.

This is why the most prestigious millworks in the United States turn to Sing Core for their large, oversize doors, though they have the added benefits of having an end product that is:

  • USA-pre-Bangkok-exportEco-friendly
  • Renewable
  • Dimensionally stable
  • Extremely Strong
  • Light weight
  • Insulated
  • Sound deadening
  • Easy to machine

And could be customized to include:

  • Waterproof
  • Fire retardant
  • Bullet-proof
  • Any Thickness
  • Almost unlimited skin options
  • Fast turnaround

The True Flat Challenge

The true flat door is a challenge for architects, door manufacturer, millworks and general contractors, especially if the door is 1 inch thick (or more), over 8 feet wide and/or 16+ feet tall.

If you’re looking for the answer, you might Google search how to build a true flat door.

Oversize doors present the biggest challenge for true flatness, but they also present other issues that must be dealt with in high end homes and/or commercial applications in terms of weight and strength. Again, let’s see what Google has to say about lightweight high strength true flat?

The clear answer is Sing Core; a new invention of material that is playing a major role – not just in building large doors – but almost anything that requires (or desires) to be Eco-friendly, functional yet elegant for inside/outside a home or in building and construction that needs to be light, strong and sustainable

Aluminum composites are common in the aerospace industry, but are cost prohibitive and not user-friendly for mill working or broad earth-bound use. Sing Core is designed to be used in millworks and does not require any specially-trained labor or specialized equipment; treat it just like you would any other standard wood-based substrate material.

Sing Core’s true flat process utilizes vertical grain torsion-box/foam-core/aluminum composites to deliver the solution. Contact us for more information, and if you like, we will show you how to integrate this new technology into your operation.

Meeting the Highest Demands

MoveWallWindowWe maintain the highest degrees of integrity when meeting the requirements of our clients, and their customers, assuring complete satisfaction. Most importantly, proper communication is the key. If you have certain expectations – and you let us know – our team can deliver the product that matches your specifications.

Simply by providing us with your dimensional requirements:

  1. height
  2. width
  3. thickness

along with what your preference for visual presentation (exterior skin material) and performance expectations are, we can provide you with the solution to best suit your application.

How Do We Do It?

When you explain to us what your expectations are, we know how to create the product that meets or exceeds your expectations. For instance, if you require a 17 foot tall oak pivot door that is true flat.

First of all, if the pivot door were solid oak, it would fail the standards test due to the raw material. Natural wood will warp, twist and crack if left to itself. Not to mention being heavy in weight. The excessive weight is an added strain on the integrity of the structure and hardware, increasing maintenance costs over time.

large-lightweight-high-strength-garage-carriage-doorsOur designers will likely prescribe a solution that begins with a Sing Core base material in the center which is by itself perfectly flat. Adding oak wood staves is where the problem comes in; because natural wood is unstable and will compromise the overall structure. To combat this issue, our team may fuse the Sing Core material to aluminum to complete the substrate composite. Then, when the exterior oak faces are applied to the structure; like magic, the result is a lightweight, super strong solution that can be perfectly flat.

The resulting Sing Core lightweight solution does not compromise the structure or the hardware eliminating expensive repairs and/or maintenance.

That’s just one example. Some of the materials used in our true flat composite resolutions that battle the temperature and moisture weaknesses that accompany utilizing natural components (like wood) include

Our lifetime of experience dedicated to solving the challenges of architects, designers and craftsmen who serve the most prestigious clientele, especially in terms of sustainable, lightweight, super strong and true flat solutions that maintain structural integrity over many years, while retaining the beauty and elegance of natural wood (or any other desired external material).

Metal is used across many industries. Metal honeycomb composite is the leader in honeycomb cores used to create stronger and lighter metal panels as well as posts and beams using much less solid metal.

Sing core is the leading technology of metal honeycomb composite material that solves our future Eco-friendly energy solution by using Sing metal honeycomb composite at a fraction of the weight of solid steel, but is stronger, lightweight, and available in steel plate, steel beam and steel panels.

Tell the US Energy Department to do some home work and research the Sing solution. If you believe Sing Core will help us use less metal thanks to Sing honeycomb metal.

Case study #1: Do not waste more precious metal if you could use Sing Metal honeycomb panel, post and beam.

Replace steel by using Sing 13 ft x 3 ft x 1 inch Sing honeycomb metal plate for use in conveyor.

1 Advantage: Precision true flat – within thousands of an inch – the majority of metal fabrication relies heavily on welding that causes the metal to deform. Sing metal uses structural glue, nuts and bolts instead of welding metal plates onto the steel frame which takes more labor, energy and end the product will not match the same precision as Sing Metal honeycomb panels.

2 Easy to fabricate and install – lightweight metal is safer to process, costs less to transport and uses less labor to install.

3 Less cost: Solid metal takes many times more metal than Sing Metal panels, posts and beams. It is expensive to transport, takes more energy to process and the most important thing is that Sing Metal is much less expensive than solid metal planks or sheets. If the strength, lightweight and Eco-friendly attributes are considered you may never go back to solid metal again.

Case study #2: If your seeking to improve your products with greater precision, true flat doors or panels, walls, floors, ceilings, RVs and/or boats then we’d like to teach you to Sing.

True Flat Guarantee premium certified true flatThis is the latest technology to build true flat doors. If we are able to build a true flat door then you can believe that we could make true flat floors, ceilings, walls, etc… all lightweight, high strength, long lasting and endless benefits just by Singing with us.

Doors are a challenge for door manufacturers and mill works if the door is over 8 ft in length and less than in inch thick.

One of the Sing aluminum honeycomb panels are used as door substrate. It used in almost all major high end residential and commercial door applications due to the true flat characteristics. AWI standards for true flat include deflection of ¼ inch, which is unacceptable for Sing Core. We can minimize deflection to 1/8th or even 1/16th according to your pre-arranged specifications and application requirements to ensure satisfaction.

But if you have a door over 12 ft – even over 16 ft tall – and less than 1.5 inch in thickness and you are wishing to have the least deflection than you need to contact www.singcore.com to find the true flat solution which is use aluminum panel as substrate than add MDF or AB plywood for paint grade door or by cold or hot press to add finish veneer to build the most beautiful, strong, lightweight eco friendly door.

Doors made of Sing Aluminum honeycomb substrate do not need to acclimatize due to there being no moisture difference on either side of the door substrate.

Sing Aluminum honeycomb door substrate can be machined or drilled just like wood without retooling or damaging your blades. It is easy to glue with proper clean up procedure.

Large over size doors for high end building project require the true flatness. Patented Sing Core is the ultimate solution for high end mill work across the country.
