Fire doors have single opening and double opening. Because of different installation occasions, it has a wide range of sizes. If it is a double-opening fire door, the size will generally be slightly larger. Fire doors need to have fire resistance tests, and the relevant authorization signs are issued by the fire department. Only then can such doors be called fire doors.
