The progress of The Times, many people began to pay attention to the quality of life, the comfort of home environment has become people to compare the areas of focus, so in recent years, aluminum alloy industrial flat open by consumers, almost any place can see it in your life, today by Jin Daoer continue to popularize industrial flat open doors and Windows material on six indicators.
1, thickness: industrial flat open 70 series, 90 series two kinds, housing 70 series can be used within the aluminum alloy sliding door. Series number said frame structure size of the mm thickness. Aluminum alloy push-pull window are 55 series, 60 series, 70 series, 90 series four. Series selection should be according to the size of humanly scaled and local wind pressure value. Used as a closed aluminum alloy push-pull window of the balcony should not be less than 70 series.
2, strength, tensile strength should achieve every square millimeter 157 Newton, succumb intensity should achieve every square millimeter 108 Newton. When the choose and buy, usable hand moderately bent profile, should be able to back after let go.
3, chromaticity, color should be the same root aluminium alloy profile, such as color difference obvious, namely, unfavorable choose and buy.
4, flatness, check the surface of aluminum alloy profiles, should be no dents or bulging.
5, glossiness: industrial flat open doors and Windows to avoid surface of choose and buy when the openings bubbles and ash (white) (black), as well as the obvious defects such as crack, burr, peeling and profiles.
6, oxidation degree, oxidation film ply should achieve 10 micron. In the light of a material surface when the choose and buy, look at the surface oxidation film can erase.
