Question:

It is good for aluminum alloy

It is good for aluminum alloy

Answer:

Aluminum alloy doors and windows of the performance / price ratio is higher than the steel doors and windows. Foreign aluminum doors and windows price is 1.5 times the steel doors and windows, that is, steel and steel doors and windows cheaper than the aluminum doors and windows 33% cheaper. However, the situation in our country is the opposite. Generally on the market, single glass plastic steel doors and windows than aluminum alloy doors and windows prices 25 to 33%; hollow double glass plastic doors and windows than the price of aluminum windows 36 to 44%, of course, these two types of steel doors and windows than aluminum alloy doors and windows insulation performance Well, but other properties of steel doors and windows are not as good as aluminum doors and windows. Hollow double glass aluminum doors and windows than the price of single glass steel doors and windows about 25% higher, however, the former insulation and sound insulation and other properties are better than the latter, for the same type of structure of the flat window, in the aluminum window (K = 2.8), the latter's price is about 24% higher than that of the former. However, the high strength and high strength of the former is higher than that of the former. Performance, excellent corrosion resistance (spray paint) and decorative effects (metal texture and non-metallic texture and other colors and boxes, window type box can be indoor and outdoor two colors), long life and other comprehensive performance is far better In the latter.
Aluminum alloy high temperature, non-flammable; is a good conductor, lightning can be anti-static; recyclable, environmentally friendly. Plastic is not high temperature, combustion; is the insulator, but need anti-static; degradation is slow, can not be recycled, slow combustion will release toxic gases, environmental impact.
It is also good for aluminum alloy. The strength of the aluminum alloy is three times the strength of plastic, wind pressure strength than plastic two high. Aluminum alloy frame cross-sectional area of only steel 1/3, window frame weight is much lighter. Plastic doors and windows due to the strength of the material and low steel, although the steel lining by adding enhanced, but its wind pressure and watertight performance than the aluminum alloy window two levels. Just because the plastic window steel lining is not in its profile lap angle to connect the complete frame system, window frame, fan four corners and the T-shaped plastic angle of penetration is relatively low, so the high-rise buildings should be used with caution.
