Hot Rolled Steel Doors

Large hot rolled steel panels being finished for installation in winery

Hot rolled steel panels high precision

Sing Core brings an Eco-friendly approach to working with large spans of hot rolled steel with less weight and more strength than plain steel pound for pound, revolutionizing the steel fabrication process. In fact, we are best known for our large hot rolled steel metal doors and hot rolled steel wall panels.

Our patented rolled steel panels feature custom metal fabrication uses high grade formaldehyde free adhesives instead of the more destructive welding process and your Sing Hot Rolled Steel Panel can host an exterior hot rolled sheet metal thickness of 16 gauge or more.

Sing hot rolled steel takes metal working into a whole new arena that is being embraced by steel companies making huge hot rolled steel products without having to use heavy steel framing.

These lightweight high strength hot rolled steel accordion doors (see video above) are 10 ft tall, each door panel is 3 ft wide and (brace yourself) only 3/4 inch thick… high precision and perfectly straight! (Try that with anything else… Only possible with patented Sing Core.)

One of the primary functions of Sing hot rolled steel products is in the area of commercial steel entry doors. If you are new to metal manufacturing, you will find that raw hot rolled steel has a more primitive or industrial feel to it, it has a less smooth surface than cold rolled steel and requires finishing to avoid rust or oxidation. The unique appearance of hot rolled steel panels appeals to designers, architects, museums, art galleries and often used in steel wall art.

Sing metal wall panels lightweight stronger than steel pound for poundEspecially if you’re considering utilizing hot rolled steel for your large doors, Sing Core can help to mitigate the damages caused by the heavy weight of hot rolled steel doors with interior steel frames that require welding. This allows you to build hot rolled steel doors of immense size that are high precision, just like other types of Sing metal.

The Sing Core material is extremely high precision (within +/- .006 inch) which keeps your hot rolled steel door straight and flat regardless of its size. The advantages of the straighter and truer big metal doors come in handy when you multiply the door’s required integrity by two when dealing with steel double doors. Double steel doors, especially if they are large and oversized, are fraught with additional challenges.

Sing hot rolled steel can be used for upscale industrial steel doors and in commercial metal door replacements for increased performance and high precision which also supply the project with built in insulation and sound deadening qualities.

Our hot roll steel solutions are changing the scope of architectural metal fabrication because the nature of hot rolled steel is predominantly restrictive due to the weight and framing required to support the raw material. Having access to a lightweight, high strength alternative, like Sing Hot Rolled Steel Panels, opens doors to unencumbered creativity.

Sing Core’s hot rolled steel doors are just some of the best doors that are among the many types of doors that have put us on the map as the best door featured in the most high end jobs across the country and the world.

You will find Sing hot rolled steel panels used not only as a standard swing door but also as hot rolled steel flooring, hot rolled steel counter tops, hot rolled steel wall panels and room dividers, hot rolled steel pivot doors and hot rolled steel sliding doors.

Wide Doors for Hinge or Pivot Door Hardware

Oversized large paint grade Sing pivot door panelExclusive to multimillion dollar spec homes, the standard extra wide exterior doors are pivot doors to accommodate the unique challenges of wide doors.

The Problem

Wide doors will warp, not just top to bottom but side to side which compromises the seal and creates a problem for latching the door. Wide doors are problematic due to warping requiring regular maintenance to adjust the wide door accordingly.

The Solution

The Sing non-warping Professional Pivot Door Panels are the solution because if the door does not warp, you’ve solved the problem with the failure of wide doors altogether, and can be guaranteed to remain non-warp for 50 years. Even $10,000 wide doors cannot be guaranteed not to warp; even for one day.

This wide door could use concealed door hinges as swing door hinges or pivot door hardware for extra wide exterior doors thanks to Sing Core

No-fail Pivot Doors

The nature of pivot doors – especially oversized large pivot doors – leads to increased maintenance costs due to warping. When you think of pivot doors warping, you first thought is to think that the door warps along the longest length from top to bottom; it is even more common side to side. Any warp will not only compromise the seal of the door but it will also prevent the door from securing and latching properly. Only Sing pivot doors can be guaranteed not to fail.

Advantages of Professional Sing Pivot Door Panels

ProfessionalSing pivot door panels are the only Eco-friendly lightweight, high strength pivot door blanks that can be guaranteed not to warp or structurally fail for 50 years.

Eco-friendly

Made in the USA professional Sing pivot door panels are manufactured using less natural resources (natural wood), recycled rigid foam and formaldehyde-free adhesives. The manufacturing process uses less energy to produce that creates little or no waste.

Lightweight Hardware

The lightweight nature of a professional Sing pivot door blank means saving thousands of dollars in labor, transportation and installation as well as the heavy duty hardware that would be necessary for a heavier door. For instance, a standard 8 ft. door would weigh-in at 720 lbs. compared to lightweight Sing Core’s 120 lbs. reducing the cost of the hardware significantly. In fact, Sing pivot doors are so light, you could use standard hinges, if you wanted to, without fail.

How to Fix a Warped Door

Many people struggle with how to fix a warped door. Nothing is more frustrating than spending your hard-earned money on a nice door, only to have it warp, bend, twist or cup not long after installation.

This problem is magnified exponentially especially if the door is a large oversized door. Some of these high-end large doors can cost tens of thousands of dollars only to discover failure due to warp when the season changes. This can mean job security for door repair services, millworks and contractors serving the account, but can lead to dissatisfaction and frustration for the client.

Patented Sing Core

Patented Sing Core

Dealing with how to fix warped wood doors is considered standard maintenance for high-end applications; that was until the invention of patented Sing Core. Only large oversized wood doors made of Sing Core can be guaranteed true flat – and to stay flat – for 50 years. See: No More warped Doors.

Sing Core solves the issues with warping and eliminates the mystery of the warping door. By integrating Sing Core into your door’s composition you can have an elegant, maintenance-free long-lasting door that will not warp, bend, twist or fail regardless of size or application.

Free Door Consultation

The most prestigious clientele around the world seek out expensive door professionals (Certified Door Consultants) to help design doors that meet or exceed the performance standards. We provide free large door consultation to trade professionals to assure that the door that your client receives delivers the high precision performance that they expect.

Demystifying Door Warping

There is no longer any need to be frightened of doors warping, due to our extensive experience in providing doors (even huge, enormous doors) that are guaranteed not to warp for 50 years to the most proficient building designers, contractors, mill works and high end door manufacturers.

The biggest problem for doors is warping (especially in large doors) used n high-end home building projects and commercial projects when building sliding doors, pivot doors and big interior doors.

Most door manufacturers and millworks avoid building doors over 8 feet tall or offer a very limited one year warranty with many exclusions/restrictions to prevent exposure to damages due to warping. Click here to see

When you buy your door, and even following installation, it may or may not be flat. Most doors begin to shift and move following manufacture. By the time your door arrives at the job site, it may already be warped or beginning to experience separation between the exterior surfaces and the core material.

Certainly after years of regular use (paper core, foam core) will warp and/or delaminate.

lightweight high strength engineered plywood for making large sliding doors aluminumNo matter what kind of standard core a door is made from, whether paper core, foam core, SLC (Stave lumber core), particleboard, SCLS (Structure composite lumber), LVL (Laminated veneer), mineral core, MDF, cardboard, etc… warping is inevitable. Even a solid wood door will warp. A sliding or pivot door will have unbearable warp at only ¼ inch due to the reference next to a straight wall or door jam. This warping is even worse in a door over 8 feet because of the strength of the movement. So far, the best solutions have been to only make 7-foot high doors, or to make excuses (i.e., no or very limited warrantees) for doors over 8 feet, or to use gaskets to hide the minor warping, but these are temporary solutions that require costly maintenance and replacement and tarnish the reputations of the building trade professionals involved in the projects. As such, most doors usually do not have warranty protection against the inevitable warping. Even with SCLC (Structure composite lumber core) and LVL (Laminated veneer), commonly used in high end large door will not remain true flat due to the wood fiber constantly moving.

Finally, Sing Core provides a guaranteed solution to the challenges of warped doors and it is the only affordable lightweight high strength solution that can provide 50 years of high performance, remaining straight and true without fail. Plus, Sing Core offers insulation qualities that cannot be found in other strong (heavy) building materials. Only this unique patented torsion box/rigid foam composite can offer the superior strength – bridging long spans, or towering heights – while insulating and providing sound deadening benefits.

Sing Core helps door manufacturers and mill workers build doors which satisfy even the most challenging high-end door market. (Click here to see our client list.) Doors made with our patented Sing core panels are true flat and may be guaranteed to stay true flat for 50 years. In addition, our patented Sing Panels (door blanks) are:

1. Dimensionally stable with a high precision tolerance of +/- .006 inch. This is laser precision which produces the smoothest and most true-flat panels.
2. Fully insulated for temperature control and sound-deadening qualities and which are 3 to 5 times more insulated than solid wood-based door cores.
3. Lightweight so that even a 4 inch thick door will weigh only 2 to 3 pounds per square foot. An average wood-core weighs 8 to 10 times more than our patented Sing core.
4. High strength which has been verified by the University of Washington at above 660 PSI, making our Sing panels pound-for-pound stronger than steel. (You could drive a 12,000-pound forklift over them without crushing them!)
5. Water-resistance/waterproof doors made of patented Sing core panels can be completely exposed to the weather without warping. (Click here to see our exterior door gallery.)
6. Eco-friendly and non-toxic structure glue for bonding skins and Sing core.

Aluminum skin only for paint grade or wood stave.

SING PANELS ARE LIGHTWEIGHT!

Click the picture to see our Sing lightweight gallery!

Click the picture to see our Sing lightweight gallery!

Patented Sing core technology is used to make Sing sandwich panels 20 percent the weight of solid wood.  Even Sing plywood is one-third lighter than standard plywood panels.  The average weight of a Sing panel is 1/2 pound to 2 pounds per square foot.  Yet, our patented Sing honeycomb/torsion box (insulated grid) core  is structured in such a way that Sing panels are inch-per-inch stronger than steel!  So, Sing panels are lightweight and strong enough to ship to anywhere in the U.S. at a fraction of the cost of shipping regular building materials.

Therefore, regular 4×8 slatwall sheets weigh in at 80 to 90 pounds, yet Sing lightweight slatwall panels only weigh 32 pounds.   An oversized door that would normally weigh  around 1,500 pounds will weigh around 300 pounds when made with Sing Core panels.  Shelves made with Sing panels are extremely lightweight yet sturdy.  Sing logs to build a dream log home  generally weigh under 70 pounds each and can be moved entirely by hand!

High Precision Doors

Foam-Panel-Interior-Structural-Torsion-Box-Sing-Core-RevealedSing High Precision Doors are a marked improvement in door development, design and implementation thanks to a newly invented Eco-friendly core material that is lightweight, insulated and stronger than steel pound for pound.

This new technology is revolutionizing the door industry especially in regards to large oversize doors. Architects, designers, mill works and door manufacturers all experience problems with doors that are larger than normal size.

Large doors present a variety of challenges in areas, like:

  1. choice of available materials
  2. lightweight doors are weak and tend to fail
  3. Copper-Doorheavy doors strain hardware and structure
  4. increased regular maintenance
  5. failure due to warping

Sing High Precision Doors solve all these issues with an Eco-friendly insulated solution.

How high precision are Sing High Precision Doors?

Sing High Precision doors are created with so much accuracy that the original door slabs are perfectly flat within .0006 inch accuracy.

After applying your desired composite materials and/or skin, your high precision door can be laser CNC machined for a perfectly flat surface, limited only by the accuracy of your CNC machine shop capabilities.

The Large Challenge

Certainly, you could use laser CNC cutting and engraving to machine nearly any door made of almost any commonly used door material for a flat result. The challenge comes from standing the door upright and expecting a degree of effective usefulness over time.

lightweight high strength engineered plywood for making large sliding doors aluminumWhy Large Doors Fail

The effects of gravity, varying degrees of moisture and/or atmospheric change, and the natural limitations of the characteristics of the building materials that comprise the door all contribute to its failure. This causes dissatisfaction for the end user, who has invested a great deal of expense in the design, manufacture and installation of this specialty large door.

Door warping is the number one problem for oversized doors that are otherwise enjoyed by the most discriminating end users.

The Disappointment

No one wants to spend that kind of money on a door that is going to warp, bend, twist, delaminate or compromise the structure or hardware with normal recommended use.

Now, here’s the exciting part…

Sing High Precision Doors can be guaranteed not to warp, bend twist or otherwise fail for 50 years!

large-lightweight-high-strength-garage-carriage-doorsImagine having a large door that can be installed that will not pave the way for repeated service calls over the life of the door.

Take a look at some of our clients who trust us with those difficult door challenges because they are the most reputable high performers in the industry who only deliver the highest marks in terms of customer satisfaction, especially now that they can deliver a fail-free large door that will not cause frustration for their client’s or their service departments.

The Large Oversize Door Specialists

torsion box plywood cutaway sing core lowes home improvement warehouseSing Core has been providing the only true flat large doors that can be guaranteed to stay flat for 50 years regardless of size.

Thanks to Sing’s patented torsion box/foam composite technology along with years of expertise of building large oversize doors that meet or exceed even the most demanding architectural door specifications and solving the challenges that face designers and builders expanding the scope of possibilities that would have otherwise been unattainable.

This new scientific process takes many factors into consideration when formulating the superior composite technology to build the biggest high-precision (within .0006 in. tolerance) guaranteed true flat doors warranted not to fail even under the most rigorous conditions.

Large doors present the designers and builders with a variety of challenges, including:

Large Door Weight and Strength

These doors are 10 ft x 16 ft x 2 1/4" thick w/marine-grade plywood exterior.

These doors are 10 ft x 16 ft x 2 1/4″ thick w/marine-grade plywood exterior.

In most cases to achieve a certain level of flatness and strength to avoid movement (warping), heavy materials, like steel, are used to maintain an acceptable degree of flatness. Even so, when using this method one sacrifices precision due to the welding process.

Compared to other materials Sing Core is the lightest weight core material that can also provide an unfaltering true flat substrate for the door. This lighter weight reduces the demands on the hardware and structure to support formerly heavy doors, while also reducing transportation and construction costs (no heavy equipment highly-skilled laborer necessary for installation/transport).

The genius of the torsion box/foam composite core is in its unparalleled strength (660 PSI in comparison to other honeycomb core material that boasts 10 to 110 PSI).

The shear strength is multiplied by the wood torsion box structure grids that can be reduced in size to achieve even greater performance results if necessary.

Warp, Bend, Twist or Cupping of Large Doors

large-lightweight-high-strength-garage-carriage-doorsLarge doors – especially those featuring natural materials, like wood, LVL or other traditional composite materials – tend to warp/fail due to exposure to the elements or temperature change in one or both sides of the door because it is inherit in the nature of wood to adapt to its surroundings by contracting or expanding.

Sing Core’s patented torsion box grids are adhered to the surface materials with the highest gripping formaldehyde-free adhesive that would delaminate from the insulated structural foam material if not for the nature of the natural wood structure grids that constantly corrects for any potential movement across the surface of the large door.

It is this science that keeps the warp-free doors flat in conjunction with composite materials that can be modified to meet the expectations of door over the expected life of the project (up to 50 years, guaranteed).

Large Door On-site Assembly

installation of large oversize lightweight high strength aluminum sliding doorThough Sing Core can build door blanks as big as 50 ft. transportation could be a problem (unless used in military applications) there are many ways of joining Sing panels on site.

The most common ways that door manufacturers deliver large doors is on separate pieces that are assembled (or stitched together) on the job site prior to installation. This is an acceptable way to transport large doors (that may have been too large to ship by traditional methods) but when assembled, the door at the site is likely to be far from perfectly flat and the seams are likely to fail, if not immediately following assembly, then in the near future.

Only Sing Core has an on-site assembly process (similar to biscuit assembly) that can provide nearly seamless results without failure. These results would not be achievable without patented Sing Core components.
