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.

Especially 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.

Core Value of Steel Doors
It is how steel door shapes the future by invention of Sing Core.

See: Steel Door Gallery

Steel door technology has not made any major improvements since the development of EPS core which has higher insulation for replacing the paper core and wood based core used previously. Sing Core uses reinforced EPS or urethane foam to fill the voids of the structural torsion-box-like vertical veneer in those highly insulated Sing products, and… Viola! You have the strength which is approximately 30 times stronger than any other regular door made of foam. Steel doors made of patented Sing Core is the leading edge door technology that provides more insulation, strength and extremely lightweight. The end result is more Eco-friendly door; stronger and lighter weight without using heavy gauge steel but creating an even stronger steel door. Click here to see the steel panel regular foam vs. Sing core

Achieve the security, safety and elegance of the most economical, advanced steel door technology to your entryway with Sing Metal Doors made in your choice of high quality stainless steel, galvanized steel or cold rolled steel.

This photo features a fully insulated 13 ft. x 3 ft. x 1 inch steel door with 20 gauge metal under 160 lbs. of load with hardly any deflection. No steel studs, no welding. See pix of steel panels ready for door applications.

Sing Steel Doors are the only insulated Eco-friendly steel doors that can be guaranteed true flat thanks to patented Sing Core’s torsion box/foam composite base material that not only ensures flatness at the time of manufacture but stays flat for centuries.

Lightweight

You get it all; Huge savings in heavy weight when compared to solid steel while exceeding standards of high-strength and built-in insulation backed by our limited lifetime guarantee at a fraction of the cost. It’s why we say, “Heavy does not mean strong – and light does not mean weak.” Sing Steel Doors weigh much less than other steel doors and do not require heavy steel reinforcement studs to achieve the high strength. Steel doors made Sing Core do not need expensive, heavy duty hardware required by regular heavy steel doors.

High Strength

Compared to solid steel doors, Sing Core is stronger than steel pound for pound. Patented Sing core could reach 1000 PSI strength vs. paper honeycomb core traditionally used in the steel industry and is changing how steel doors are made. Sing steel doors will not dent or kink like regular hollow core, paper core or foam core steel doors.

Economical

Patented Sing Core costs a fraction of high-end honeycomb substrates, like those used in traditional aerospace applications, and still outperforms any of them in lightweight, high-strength, eco-friendly economical solutions bar-none. And that does not even take into consideration the reduction in transportation/installation costs and reduction in maintenance and repair costs over time.

No Welding

Sing Steel Doors are manufactured without welding which reduces labor costs, environmental and health hazards and our patented method will not compromise the integrity of the steel surface of the steel door, like welding does. No need to compromise the integrity of your steel doors by incorporating the most high precision Sing Core (+/- .006 inch) material and our patented metal fabrication process.

Lightweight High Strength Eco Friendly Metal Pivot Doors

When professionals seek out extraordinary, unique and/or oversized modern steel doors the most conscientious purveyors settle on a Sing Core metal pivot door.

While exquisitely masterful in their design, modern metal pivot doors present many challenges. The first challenge to overcome is that of excess weight. Due to the size of the door – if it is constructed simply of metal – the door is just not practical due to its excessive weight.

What you want is an

Extraordinary metal pivot door with a unique, bold and striking appearance

(see samples of contemporary metal pivot door finishes to the right…)

That has these characteristics:

Lightweight
High strength
Eco-friendly
Affordable

To combat this challenge door manufacturers seek out composite materials to incorporate into the design of the metal pivot door to deal with the heaviness of the door that causes a strain on the structural integrity of the frame, the hardware and project overall.

Solid steel pivot doors, while impressive, are just not practical, yet engineers have found ways to circumvent the obstacles in an effort to retain the appearance of being a solid steel pivot door.

The next challenge to overcome is that of strength. By compromising the metal pivot door’s integrity by not being constructed of solid metal, other cores are considered to reduce the weight of the metal pivot door.

Normal alterations include, using a lesser-strength metal core. Using a metal tube substrate or honeycomb core will match the structure of the metal door, but compromises the overall strength, while resulting in a metal pivot door that is still extremely overweight.

Engineers in search of a more lightweight solution, then consider composite materials to fill the core of your metal pivot door. These include natural solutions, like wood, or manufactured solutions, like foam. While wood products are an option, if solid, are still too heavy to result in a lighter weight solution, and still cannot compare to the strength of a solid steel door. And though foam is lightweight, it simply has no structural integrity and fails the test of strength altogether. Also, over time, these core components tend to lose their integrity, and rarely (if ever) produce an end product that is true flat.

Another consideration is that of excessive energy and harm to the environment expended in the creation of your metal pivot door. The process of creating a metal pivot door with metal interior components requires a lot of wasted energy consumption and highly-skilled laborers (welders) that not only makes the door non-eco-friendly, but results in a very expensive end product.

Sing Core can host any metal material, like stainless steel, iron, copper or aluminum and is the solution for all these considerations, providing the designer, contractor and end-user with all these benefits, and more…

Sing Core, when used as the substrate of your metal pivot door will not compromise the exterior metal beauty and magnificence of your door, which is the primary concern of this exciting, bold design choice.

LIGHTWEIGHT, HIGH-STRENGTH & TRUE FLAT

Sing Core is extremely lightweight, yet stronger than steel over any given spans and is the primary reason why it is selected over other types of composite core materials by high-end users; solving both the challenges of lightweight and high strength. It also creates a surface that is true flat, and retains its flatness over time. Every Sing Core metal pivot door comes with a 10 year warranty.

ECO-FRIENDLY, MADE IN THE USA

Sing Core is also eco-friendly. As Sing Core is manufactured, the process uses very little energy, utilizes renewable materials and produces little or no waste. Sing Core is also proudly manufactured in the USA.

INEXPENSIVE

Sing Core is economical to use. Using less-skilled labor to create Sing Core makes it an affordable option. Not to mention the reduction in costs of hardware and installation.

Don’t we all want a beautiful metal pivot door that is a bold design feature revered in modern architectural circles?

Shouldn’t yours be lightweight, have high strength and be earth-friendly?

Certainly, we would expect to pay more for this technology, but Sing Core is so affordable, think of what more good you could do for the world by saving costs of production and installation, let alone your bottom line.

Sing Core’s lightweight, high strength, eco-friendly metal pivot doors are the unequivocal answer for the discriminating modern pivot door designers today.
