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.

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.

Add MDF skin or plywood for paint grade and wood grain.

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.

Solid Wood Stave Door Blanks

Our panels make doors!

Patented Sing Core solid wood stave door blanks feature the newest technology in the door industry for composite doors yielding the only eco-friendly, lightweight, fully insulated, high-strength doors with wood blanks of any size (up to 40 ft.) that can be guaranteed true flat and to stay flat for 50 years.

Large door versus regular-size door challenge (i.e., over 4 feet wide and over 8 feet in length):

Large doors are heavy, dimensionally unstable, require more strength due to the heavy weight, and are a challenge to manufacture, ship and install.  High-end jobs require precision and true flatness to please the customer.  A homeowner’s architect, general contractor and mill worker must solve the problem of warping doors.  The solution to the challenge is to use patented professional true flat Sing panels to make your doors.

Sing Core wood stave door planks are the only solid wood doors that will not warp, bend, twist or cup following installation.  This means no more continuous service calls for maintenance of big doors that cannot possibly stay straight due to the limitations of solid wood – or any other door core – that is subject to failure.  Sing panels have a patented honeycomb/torsion box interior which gives lightweight yet unsurpassed strength (pound-per-pound stronger than steel) and stability to any door, and allows Sing Core to provide a 50-year guarantee

Interior Doors:

Sing panels make amazing designer doors in any style.  With Sing panels, fragile doors such as French doors are made lightweight yet strong, not warping or breaking hinges, which will last for many decades.

Exterior Doors:

Sing panels make sturdy exterior doors in any style.  With Sing panels, exterior doors are lightweight and strong, even when oversized.  Our professional doors are guaranteed to stay true flat and not warp or twist for 50 years

When is a door not a door? When it fails to function as a door.

The problem is that all door core materials are either not high precision, too heavy or will move when exposed to moisture, humidity or change in temperature resulting in door failure.

Heavy solid metal or steel will not warp, bend or twist, but is not high precision due to welding (sing core tolerance is + or –  .006 inch!) and is often impractical due to the overweight issues causing excess strain on both the hardware and structure, causing continued maintenance issues.  The solution is our patented lightweight yet strong Sing core technology.

Finishing a door blank:

There are two types of finish for door blanks:  paint grade and wood grain.  Paint grade includes such finishes as metal, Masonite, marine plywood, etc.  Wood grain finish includes such finish as solid wood stave and thin veneer.

Why Use Solid Wood Instead of Veneer?

solid wood composite door planks any size thickness true flatNever settle for substandard veneer doors again. Door engineers prefer to use inexpensive veneer as opposed to real solid wood facings because veneer is thought to be less likely to warp, bend or twist.  But thanks to the super-strength of patented Sing Core technology, you can use solid wood stave and wood blanks with confidence knowing that your door can be guaranteed true flat and will stay flat.

How can a solid wood-faced door stay true flat? As every woodworker knows, when using a solid wood surface, the grain will move according to moisture or temperature change causing the door to fail. When using our patented Sing Core as a substrate you can safely use solid wood because the solid torsion box/honeycomb patented material is continually keeping the wood grain straight and true.  Whereas wood stave has more wood fiber giving it more of a chance to warp than thin veneer due to the unbalance of the both side of the door moisture contents, patented Sing technology solves this problem by combining stiffing skin on both side of our patented Sing core.  This Sing panel technology eliminates the troublesome movement of the door blank — warping is no longer a concern when wood stave is combined with patented Sing core.

In addition, solid wood is easy to work with, install (no need to hot press), repair and remodel.  That’s why professionals trust Sing Core’s years of expertise in helping to design the only wood stave doors (that look just like solid wood doors) that can stay straight and true for many decades while respectfully honoring the beauty and elegance of solid wood, which far outlasts easily-damaged veneers, yet can be sanded and repaired if necessary.

Celebrate your real wood!

solid wood stave door planks lightweight honeycomb guaranteed 50 yearsOur Eco-friendly lightweight, high strength alternative is the best   solution for combating the issues associated with weight and size,   especially large doors.  Only our patented Sing torsion box/foam   composite core combined with our years of experience provides   guaranteed solutions for oversize doors.

That’s why this technology is found everywhere, from beneath the sea   (US Navy) to outer space (NASA) and everywhere in-between.

Sing panels may be finished in almost any wood species, like   mahogany, redwood, teak wood, cherry wood, walnut wood, cedar   wood, Ipe wood, sapele wood, poplar wood, ebony wood, ash wood,   oak or any other hardwood or exotic wood types available.

This same wood blank composite technology is also a common solution for high-end projects like engineered hardwood flooring, shiplap, wood furniture, wood shelves, decking, shed doors or any other application demanding high precision and exemplary performance over time.

How is wood stave/veneer added to Sing panels?

Wood stave is added directly to the metal or wood skin our patented Sing cores.  Wood veneer is added to an 1/8-inch mdf attached to the metal skin.

Aloha Non-warping Hawaiian Large Doors

Aloha from Honolulu, Hawaii, where Professional Sing non-warping doors are making an impact.

3 views of best pivot door lightweight high strength non warp insulated pivot doors

Hawaiian door manufacturer sought out Sing Core in search of a non-warping exterior door solution for rigorous climate variances especially large oversized sliding doors and pivot doors.

During the free consultation, the manufacturer explains that large doors are known for warping top to bottom, but people don’t talk much about warping side-to-side, which makes it a constant struggle for latching and sealing the door. These are the constant issues that face the makers of large exterior doors.

Large oversize non warping wood pivot door insulated modern pivot doorsThe specifications for the door included a natural Sapele wood stave exterior which complicates the door project even more because the innate natural wood grain will have a tendency to warp, bend and twist according to changes in temperature and humidity.

Door manufacturers find it hard to believe that inventor Peter Sing would be willing to, “put his neck out on the line for 50 years.” It is this 50 year non-warp and structure guarantee that intrigues manufacturers of larger doors, especially if the door specs include exposed solid wood.

The undeniable fact is, patented Professional Sing Core is the only way to build a lightweight, high strength non-warp door. And Sing Doors are guaranteed not to warp – top-to-bottom or side-to-side – for 50 years including full structure guaranteed also.

We are the best door substrate for doors, not just in the continental USA, where we are best-known but also in Alaska and Hawaii, when it comes to the most prestigious big doors.

Here’s an example of a 98” x 84” x 3” Professional Sing Door with custom lite cutouts for a modern pivot door presentation and 1/8” Sapele wood stave exterior, weighing in at only 250 lbs.
