WHY STEEL ?
STEEL
IS AN INCOMBUSTIBLE MATERIAL
 |
STEEL
has a melting point of 1,600 deg. C.
|
 |
In
a Fire Test, the door is subjected to a furnace
Temperature of 900 deg. C after 30 minutes.
|
 |
As
timber is combustible, it feeds a fire as fuel. It may
serve as a fire barrier for a very limited time but it
actually contributes to the heat, smoke and fire! |
