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.

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.

* 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.
**Customer will need to perform lab tests to certify hurricane rating for local code compliance.
Lightweight High Strength Eco Friendly Metal Pivot Doors
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?
