1. The thickness of the fire door
The main fire doors on the market are generally divided into two types: steel fire doors and wooden fire doors. The thickness of the wooden fire door is about 50mm, and there are regulations requiring that the door frame and the door leaf with a thickness greater than 50mm should be connected by a double tenon. The thickness of the steel material used in the steel fire door is: door leaf panel ≥0.8 door frame plate ≥1.2 hinge plate ≥3.0 reinforcement without screw holes ≥1.2 reinforcement with screw holes ≥3.0.
Second, the length and width of the fire door
The standard fire door size has a range, and the fire door logo can be brushed if the width is 1800mm*the height is 2400mm, which can also cover this range. The height of the Class B fire door can reach 2700mm, but there is one point, the net height of the bright window and door above the Class B fire door is 2400mm.
There are standard size fire doors, and there are also non-standard fire doors. The size range of non-standard fire doors is generally higher than width 1800mm * height 2400mm. In mid-2013, in order to further standardize the size of fire doors, the Fire Department revised a regulation on the production of fire doors. The size of the previous doors that can be covered cannot be covered this year. Simply put, it is one size and has a Of the logo.
In fact, the national standard does not stipulate the size of the door, only the fire resistance of the door is required. In general, fire door drawings are marked with FM0615, FM0618, FM1018, FM1218, FM0921, FM1021, FM1221, FM1521, FM1821, FM2121, etc. The largest ones are FM2421, etc., as long as the height does not exceed 2100mm, then these specifications and dimensions are standard Yes, but the test report is generally marked with a large size. However, remember that the size of the inspection report must not be smaller than the size of the door used on site.
Although the country does not clearly stipulate the size of fire doors, they must be qualified according to the standards marked on the drawings of fire doors.
