Thickness: 0.18mm-1.5mmWidth: 480mm-1,250mmCoil weight: as per customers' requestsID: 508mmApplications: general use, construction industry, household appliance industry, automobile industry and industrial instrumentsPackage: export standard package or as per customers' requestsOrigin of production: ChinaProduct properties: according to the weight rate, the coating layer of the hot-dipped galvalume steel plate consists of 55% aluminum, 43.4% zinc and 1.6% silicon.

 The distinctive features of the hot-dipped galvalume steel plate lies in its excellent properties of erosion resistance and damp heat resistance; the erosion resistance of the hot-dipped galvalume steel plate is 2-6 times higher than that of the ordinary hot-dipped galvanized steel plate. The damp heat resistance of hot-dipped galvalume steel plate is more than 3 times higher than that of the ordinary one.

Meanwhile, as well tried, the hot-dipped galvalume steel plate has the high temperature erosion resistance property. The hot-dipped galvalume steel plate will not fade after being oxidized for a week (168 hours) at a high temperature of 315°C. Even at a temperature as high as 700°C, the hot-dipped galvalume steel plate can still be free from severe oxidization and scale formation while the highest working temperature for the ordinary galvanized steel plate is only 230°C. Besides, the hot-dipped galvalume steel plate has good cold-roll forming performance, stationarity, weldability and painting viscosity. What's more, because of its handsome appearance, the steel plate can be put into application without being painted
