1, fire shutter fire-resistant time problem:
Fire shutter fire prevention performance of classification is no national standard, GB14102 "steel fire shutter general technical conditions" in ordinary steel fire shutter is divided into:
Level 1, refractory time 1.50 h
F2, refractory time 2.0 h
The composite steel fire shutter is divided into:
F3, refractory time 2.50 h
F4, refractory time 3.00 h
Dual-track double curtain cloth of inorganic fire shutter fire-resistant time: 3 h
2, fire shutter sealing of size:
Steel anti-fire rolling curtain packing size: 500 mm * 600 mm width < 6000 mm, and height (standard size: < 4500 mm)
Double double sealing curtain cloth inorganic fire shutter size: 500 mm * 500 mm
3, fire shutter weight problem:
0.6 mm steel anti-fire rolling curtain degrees per square meter in 20 kg weight, about 0.8 mm thick around 25 kg so of course this is not an accurate weight.
The weight of the inorganic fire shutter cloth in about 10 kg/square meters.
