About Metal Doors with Sing Core Inside

Metal doors which are made using the patented and patent-pending Sing Core technologies are celebrated around the world as being the best metal doors in the world.

Why Do You Need Sing Core Inside Your Metal Door?

Metal Door Problem

Its well-known metal doors are neither Eco-friendly nor sustainable solution and they have the potential to fail more often than not for a variety of reasons. Metal doors warp when hit by the sun’s rays, or exposed to heat or cold, and if there are varying environments on either side of the metal door, such as an exposed exterior metal door, you know trouble is not far away. Also metal doors are extremely heavy which causes hardware or the structure to fail due to added stress and strain due to the heavy weight. Plus, the bigger the metal door, the more likely it will fail and require expensive maintenance calls to repair or replace.
