The Battle of aluminum alloy doors and windows and plastic steel doors and windows
20 aluminum windows and doors in the early 1980s the advent of our country, due to the unique advantages of its light weight, corrosion resistance and so gradually replace the original steel window by consumers. Made of aluminum alloy metal elements, has the advantage compared to other material, light weight and high strength, various periods may be extruded into a variety of new complex cross-section of the material. The new patented bone color stainless steel anti-theft window overcome the poor market performance of existing anti-theft security windows, rust, a single color, prison cage and strong sense of shortcomings. Not only color variety and never rust, steel reinforced by the internal use of standard parts assembly, while increasing anti-theft performance of more decorative, product quality has improved significantly. But over the past two years, the domestic steel doors and fast development, has caused significant impact on the aluminum windows and doors market.

Some people think that aluminum door and window frame thermal conductivity coefficient strong, unfavorable thermal insulation, plastics and insulation, can save energy. For this argument, China Building Decoration Association of aluminum products Committee of Experts that, in fact, the main insulation glass, window frames and not issue material.

1, noise performance  Statistics show that noise performance is much better than steel doors and windows aluminum doors and windows. For example: to achieve the same noise requirements of the building, construction and transport corridors from the installation of aluminum windows and doors to be 50 meters away, if the steel doors and windows can be reduced to less than 16 meters.

2, thermal insulation properties  mentioned insulation performance, we need to compare the basic technical parameters of the material, for example PVC thermal conductivity material is 0.14, and the aluminum was 175. In other words, under the same conditions, in terms of material thermal conductivity, aluminum is 1250 times the PVC material. Of course, if the doors and windows made of PVC, conducted comparing the energy consumption, it is difficult to generalize. Because the indoor heat loss, usually associated with roof, floors, walls, and doors and windows. However, research data show that as an ordinary house, the same open air, installed steel doors and windows of the room than the room installed energy-saving aluminum doors and windows every day to more than 5 degrees.

3, the corrosion resistance of  steel doors to acid, alkali and other corrosive chemicals, it is not afraid of erosion urban pollution, acid rain and the like, and hydrochloric acid. The aluminum is not, after the case of easily lead to surface oxidation corrosion and shorten life.

4, the installation performance and service life of the windows  steel doors is much lower than the weight of aluminum windows and doors, but because it is integrally formed, quickly installed, so that the overall efficiency is greatly improved. Aspects of life, steel doors and windows of the normal service life of 30-50 years, lower than the aluminum doors and windows.

5, process performance and product design  steel doors and windows and aluminum doors and windows can be designed according to the requirements of the designer made into flat open, sliding, and the curved windows hung, Fang Xinying large attractive appearance. Steel doors and windows can be colored surface, coating, coextrusion multicolor; aluminum doors and surface coating, electrophoresis, color can be achieved also diversified.
