warp free designer doors | Non-warping patented wooden pivot door, sliding door, and Eco-friendly metal cores

What do you want in your door to be straight and true, keenly and perfectly curved, or to reach the highest heights?

Sing Core enables architects and designers to see their creative ideas come to life, especially in terms of making the largest contemporary modern doors, out of any material you want, and (here’s the best part), be guaranteed to be true flat and warp-free for 50 years.

Big does not have to mean heavy, nor does it mean that you have to fear that your magnificent creation will fail due to warp. No need to worry, thanks to inventor Peter Sing’s patented and patent-pending warp-free large architectural door solutions.

Big Warp-free Doors

The fact is, nobody can make an Eco-friendly lightweight door that is stronger than steel and can be guaranteed not warp, bend, twist, or otherwise fail for 50 years. Not unless it has Sing Core inside.

Look how perfectly straight these big doors are.

Perfectly Curved Doors?

But what if your creative juices got flowing and you dreamed of having a perfectly curved door?

At first blush, you might think that was the absolute opposite of a warp-free door, but the designer is dead serious about the curve in this door remaining just as accurate and true over time. Look at this perfectly curved door.

Even if curved, Sing Core can guarantee this door to keep its curvature over time, guaranteed for 50 years.

Sing Doors Reach the Highest Door Height in America

If that wasn’t enough, you will find the tallest doors on the top floor of the tallest building in the United States of America reaching the highest height on the 89th floor of World Trade Center One’s Freedom Tower in New York, NY.

The creation of these doors were entrusted to inventor Peter Sing’s True Flat Team to create these one of a kind warp free tall pivot doors which are proudly made in America as our commitment to exercise our individuality and pride in American ingenuity.
