Pivot door manufacturers are the backbone of the success behind the impact patented Sing Core is seeing in contemporary architecture design and modern pivot doors around the world. Where the power of these emerging technologies really shines is in modern pivot entry door, but none of this would be possible without the support of the biggest and best high-end pivot door manufacturers.

Patented Warp-free MDF Door Core for Pivot Door Manufacturers

The growing trend of modern pivot doors is often pushing the boundaries of size, where it is generally assumed that the bigger the pivot door is, the greater the impact it will have on those who encounter such a giant articulating pivot door.

It gets more complicated the larger the pivot door is because you are attempting to surpass the limitations of the materials used to manufacture these highly customized pivot doors, especially if you are working with a modern pivot front door.

A modern pivot front door is more far more complicated to manufacture due to its having one side which faces the project’s interior and the other facing the exterior, and could be exposed 100% to the elements, and as they change, the materials begin to move. Given enough movement as the door adjusts to the environmental changes, will cause the door to fail. It may not operate freely, adding stress and strain to the pivot door hardware, compromising the pivot door’s ability to seal correctly, and it may become impossible to secure as locking mechanisms may not line up properly.

This is the plight faced by the best pivot door manufacturers, and that’s where inventor Peter Sing’s patented modern pivot door solutions come in, which have been changing the way modern pivot doors are made.

The Sing Core Solution


Pivot Door Manufacturers

Pivot door manufacturers rely on Sing’s ability to match up the perfect modern pivot door core substrate to both the size and materials to create a pivoting front door that will not fail. Backed by Sing’s True Flat Team, his factory, located in the pristine Pacific Northwest in McCleary, Washington, they are able to provide these high-end pivot door manufacturers with the exact door core to match supplication, size, and materials.

The result is a modern pivot front door which will not warp, bend, twist, or otherwise fail for a full fifty years. (No, that is not a misprint.) The modern pivot door cores with Sing Core inside can deliver a large pivot door made of nearly any flat building materials which can be

Guaranteed Warp-free for 50 Years

This is an unprecedented warranty that can not be achieved without having patented Sing Core inside.

Sing’s patented technologies enable modern pivot door designers to expand their horizons and to exceed high performance standards which would normally be limited to what was previously possible using existing technologies and materials.

What makes Sing’s core so special?

Sing’s core is a hybrid composite technology which combines traditional woodworking craftsmanship and space-age technology to accomplish this feat.


Sing starts with a torsion box grid structure, which has long been known as an effective way to make a large lightweight door with increased dimensional stability. Sing multiplied the strength of the torsion box by making the torsion box grids smaller (2 to 3 inches) and achieved even more strength by flipping the grain orientation to vertical. Then he fills the vertical grain torsion box voids with recycled foam. Sandwiched between two stress skins and cold-pressed with formaldehyde-free adhesive, results in a solid modern pivot door core perfectly matched to the specific needs of the most discerning pivot door manufacturers.

Since the inception of Sing’s core, he has also developed patented and patent-pending anti-warp mechanisms which can be inserted into the core at precise locations to prevent warping of any modern pivot door surface material.

For instance, wooden pivot door manufacturers know that they will receive a one of a kind sing solution for a large wooden pivot door that will be unique and different for each type of wood featured on their warp-free in wooden pivot doors. Whether the doors are white oak, walnut, mahogany, teak, cherry, or cedar, the core will be different. And if it is to be used as a modern pivot front door, even more specialized.

When people hear about Sing’s special technologies, of course, everybody wants a pivot door with Sing Core inside, and they may reach out and contact Sing Core for such a door, but Sing does not build the doors for which he is so well known. Sing only supplies the top pivot door manufacturers with the components which makes these doors possible.

Believe me, you wouldn’t want what he ships to the pivot door manufacturers, it doesn’t much look like a door, but what the pivot door manufacturers do, is to create the most beautiful and most magnificent modern pivot doors using Sing’s core as their canvas.

It is the perfect synergy between the pivot door manufacturers and Sing’s core, resulting in an interior or exterior pivot door that is lightweight, high strength, fully insulated for sound deadening and increased climate control, and can be guaranteed warp-free for 50-years.

And remember, Sing core can support nearly any available flat building material, including but not limited to, aluminum, brass, cold rolled steel, copper, diamond plate steel, fiberglass, Formica, FRP, galvanized steel, hot rolled steel, HPL, Kevlar, Masonite, magnetic white board, stainless steel, and of course, any type of available wood species.

Sing’s core is stronger than steel pound for pound, rated at 660+ PSI and features the highest precision, which is also very highly sought after by the most prestigious end users.

That’s why you could find Sing’s core anywhere from beneath the sea (US Navy) to outer space (NASA) and anywhere in between.
