Aluminum roofing sheet is also known as corrugated aluminium sheet, profile aluminum sheet, aluminium tile, aluminum manganese magnesium alloy etc. From its last name we can know that aluminum roofing sheets are mostly of 3000 and 5000 series of aluminium. 3000 series contains Al and Mn, well known for its anti-corrosion property, and 5000 series has Al and Mg, better known for anti-rust performance. Generally speaking, 5000 series has lighter weight, stronger tensile strength and higher hardness.

As a type both 3000 and 5000 series of aluminum roofing sheets have the following features. First, they have smaller density than their competitors, only one third of steel, so they weigh much less. In spite of higher prices, they cost almost the same with steel of the same size and thickness. Second, it’s easy to process aluminium sheets into roofing sheets, for they have excellent plasticity and workability. Various designs can be made in accordance with special requirements. Installed conveniently, they help to reduce construction task substantially. Third, they are bright and grand, taking on an attractive outlook. Fourth, they have a long service life. Boasting excellent corrosion resistance, aluminium roofing sheets last long in acid, alkaline or salty environments. Fifth, they have better recycle value than iron that gets rusty within years. Aluminum sheets does not get rust over a long period of time, and at least 80% of them can be safely recycled.
