Of window of model steel door, as a new type of building products, nearly two years in Windows and doors market boom, the market share of more than ordinary wood, steel doors and Windows, color plate doors and Windows, as aluminum alloy doors and Windows. More data show that the next century will is the world of window of model steel door, at the appointed time, aluminum alloy doors and Windows will be relegated to a corner, to be eliminated. Then, window of model steel door with the relative merits of aluminum alloy doors and Windows? We might as well by the following performance characteristics to compare.
1, the sound insulation performance
According to the data show that the sound insulation performance of window of model steel door is greatly better than that of aluminum alloy doors and Windows.
For example: up to the same noise requirements of the building, installation of aluminum alloy doors and Windows of the building and the distance of the traffic artery in 50 meters, if use window of model steel door can be reduced to 16 meters.
2, heat insulation,
Mention heat insulation performance, we need from the material basis of technical parameters, such as PVC material coefficient of thermal conductivity of 0. 14, and aluminum alloy 175. That is to say, under the same conditions, in terms of material heat conduction ability, aluminum is 1250 times of PVC materials. Of course, if the PVC Windows and doors, compared the energy consumption, it is difficult to generalize. Because indoor heat being lost, usually related to the roof, the floors, walls and doors and Windows. But the scientific research data show that as an ordinary house, open air conditioning, also with the room of window of model steel door than aluminum alloy doors and Windows of the room every day to more than 5 degrees.
3, corrosion resistance,
Window of model steel door to acid and alkali resistance and other chemical corrosion, is not afraid of the urban environment pollution, such as hydrochloric acid and acid rain erosion. And aluminum alloy is not, after the encounter corrosion is easy to cause surface oxidation, shorten service life
