Fire doors are divided into steel fire doors, wood fire doors, steel wood fire doors and fire doors made of other materials. From the perspective of fundamental fire resistance, steel fire doors are better than other products of the same type in terms of their own structures and internal fillers. Wooden fire doors are definitely not as fire resistant as steel ones.
