Hebei Hong Security Firegate Co., Ltd. manufactures a large number of wholesale bridge cutoff aluminum refractory window 、 aluminium alloy Fireproof windows, aluminum alloy fire-proof windows, steel fire-proof windows. Low price, high quality
Price of steel non insulated fire-resistant window of steel fire-resistant window manufacturer
Hebei Hong'an Fire Protection door The steel non thermal insulation fireproof window produced by the Company is comparable to the aluminum alloy fireproof window. Its price is 150 yuan per square meter lower than the aluminum alloy fireproof window, and its strength is twice that of the aluminum alloy fireproof window. The surface spraying treatment can be the same as that of aluminum alloy. The profile of profile * * * aluminum alloy is the same as that of aluminum alloy in terms of sealing and defense. Thermal insulation is consistent.
Hebei Hong'an Fire Door Co., Ltd. specializes in the production of inorganic super grade fire shutter doors, large-span profiled inorganic super grade folding and lifting fire shutter doors, steel fire shutter doors, lateral fire shutter doors, stainless steel fire shutter doors, fire doors, fire windows, and smoke barriers. Wholesale inorganic fireproof rolling curtain (curtain surface) 31 yuan/m2 and curtain pieces.

[Specification for bridge cutoff aluminum fire-resistant window]
According to the new regulations of the Standard for Fire Protection Design of Buildings, it is not allowed to use B2 level thermal insulation materials and B1 level thermal insulation materials in densely populated places for residential buildings; In non crowded places, when the building height is ≤ 27m, and B2 level insulation data is used, the fire resistance integrity of doors and windows on the exterior wall of the building shall not be less than 0.50 hours; When the building height is>27m, the fire resistance integrity of the doors and windows of the external wall of the building shall not be less than 0.5 hour if the B1 thermal insulation data is used;
1. Good thermal insulation: low thermal conductivity of PA66 nylon in bridge cutoff aluminum fireproof window profile
2. Good sound insulation: its structure has been carefully designed, and the joints are tight. The test results show that the sound insulation is 30 db, which conforms to the relevant requirements
3. Impact resistance: because the external surface of the bridge cutoff aluminum fireproof window profile is aluminum alloy, it is more impact resistant than the plastic steel window profile. 4. Good air tightness: multiple sealant strips are installed at each crack of the bridge cutoff aluminum window profile, with good air tightness,
5. Good water tightness: doors and windows are designed with protection
The fireproof window manufacturer tells you the precautions for the use of fireproof windows
(1) The fireproof window is made of steel, which can be divided into two types: false grade (fire resistance limit 1.20h) and grade B (fire resistance limit 0.90h).
(2) Fireproof windows are mainly used on the firewalls of high-rise buildings, and it is required to use fake fireproof windows that can be closed by themselves.
(3) When the horizontal distance between the doors and windows on both sides of the firewall is less than 2m, the steel fire-resistant windows shall be sold in stock, and Class B fire-resistant windows shall be used.
