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.

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

Honeycomb-Skin-Material-Options-Metal-AluminumYou 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

no-welding-free-metal-fabrication-lightweight-eco-friendly-stronger-than-steelSing 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.

Custom Lite Openings

Sing Steel Doors can come complete with custom lite opening cutouts for adding glass to your door. You are not limited to the type, shape or style of cutout for your glass opening. Other steel door companies offer a variety of window openings to select from. Sing Steel Doors allow you to create any glass enhancement that you can imagine.

* 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.
