Galvalume wave tile is also called Galvalume corrgated sheet,which is made of ordinary galvalume plate. To prevent the oxidation of the steel surface and prolong the life of the steel plate, it has to be pre-coated with aluminum and zinc on the substrate. Hot dipped 55% aluminium zinc alloy board no rust marks after 20 years later, but relative galvanized sheet about ten years. Based on the corrosion weight loss measurements, it is found that the corrosion performance of a 55-aluminum-zinc alloy plate can be more than 50 years old.
Developed from hot dipped zinc galvanized and hot-dipped aluminum galvanization tech, galvalume steel combines with excellent characteristics of both products, premium corrosion and oxidation resistance of hot dipped aluminum galvanization and exceptional electrochemical properties of hot dipped zinc coated galvanization, which gives galvalume steel strong anti-rust and anti-corrosion ability at the edge and on the scratched surface.
The corrosion resistance property of the 55% aluminum zinc steel roll is from the aluminum layer barrier protection function and the sacrificial protection function of zinc layer. When the steel roll happens trimming, scratches and abrasions, the zinc will take the role of sacrificial coatings to protect the steel's anti-corrosion, the aluminum will form an oxide insoluble protection barrier layer.
Hot dip galvalume corrugated sheet by cold rolled steel sheet,then trough chromated, unoiled,various spangles,hot dipped.The surface of SGCC/SGCH/DX51D/ JIS G3302 full hard galvalume coils is coated by zinc and aluminum.It is widely used as the raw material building.We have exported our products AZ coating 40-150g/m2 galvalume steel coils to South America,Ukraine Middle east,Africa for the good quality and best credit.
Supereal Enterprise Limited is a professional company ，We have advanced production equipment, experienced sales team and strict quality control system to ensure the quality of steel plate.
