As a new type of roofing material in construction, aluminium roofing sheet wins wider and wider popularity in the market, gradually replacing colored steel sheets. Why would people like to choose aluminium roofing sheet rather than traditional steel sheet? Because the former boasts overwhelming advantages over the latter.
Aluminium roofing sheet has extraordinarily long service. Generally speaking common steel sheets last five years before being rusted. In regions with severe natural conditions, you may have to replace them every three years. Aluminium roofing sheet, made of combining materials of aluminum, magnesium and manganese, can last as long as fifty years under natural circumstances. That’s because the sheet is of strong corrosion resistance which becomes stronger after being anodized and coated. In regions where acid rain falls a lot usage of the sheet has become a trend. Except for long service life, the sheet also has lower price than steel sheet. The density of aluminium sheet is 2.73g/cm3, only one third of that of colored steel. In other words, you get two times of square meters of aluminum sheet more that that of steel sheet for the same weight. Last but not least, aluminum roofing sheet can be recycled at much higher prices. After being rusted, colored steel roofing sheet costs less than 1RMB per kg, while you can sell discarded aluminum sheet almost with its original price.
There are kind of colors to choose from including metallic and special finishes.
