1. Differences in grades: China break hot window of aluminium alloy profile and model steel window is suitable in different engineering construction of purchase crowd, statistics show that the model steel window is generally low layer housing, usually customers for the goods of this type of class device quality regulation is not very high, and high performance fault hot aluminium alloy window are various relative height, apply to all kinds of grade of engineering construction, And the quality, service life performance has stood standardized hone.

2. The difference in performance: the actual effect of environmental protection and energy saving is similar; But because 40120 aluminum material difference, plastic steel window application after a period of time is very easy to produce deformation, sealing performance is not as good as high performance aluminum alloy window.

3. The difference in service life: because 4040 European standard aluminum material strength and elastic mold and wear resistance performance difference is relatively large, so that the service life of high-performance aluminum alloy window usually exceeds the service life of plastic steel window.

4. The distinction on price: say commonly, the price of window of high performance aluminium alloy window wants a few taller than the price of window of model steel normally. But from long-term consideration, high performance aluminum alloy window price although high, but the service life is long; And although model steel window price is cheaper, but use fixed number of year is short. Therefore, aluminum profile stair comprehensive price comparison is very.

Aluminum doors and Windows compared with wooden decorative design Windows and doors and their gradually eliminated general empty belly or solid belly plastic steel doors and Windows have obvious application performance, its air pressure compressive strength performance, gas infiltration performance, precipitation water leakage performance, gas sound insulation performance, thermal insulation performance and open and close performance, etc., do the industry standard requirements; And because of the characteristics of aluminum alloy profile material, so that its production, aluminum alloy profile installation and product installation can achieve a higher precision, for engineering construction of the electrical design of shelving structure and the application of safety and other specifications to give the key and essential standards.

Aluminum alloy window and Ningbo aluminum profile is relatively indicated
