Wholesale Wooden Doors Fire Rated
Wooden fire doors are divided into two series: full-board and half-glass, as well as single and double-leaf doors. It is very important to control the moisture content of the wood (including plywood) used in the fire-resistant wooden door, it can keep the door in a proper gap, operate normally and not crack, and the wood needs to be flame-retardant treated before it can be used.
