G550 Hot Dipped Iron Zinium Aluzinc Galvalume Steel Coil/Sheet For Building

Short Description:

The coating structure of the aluminum-zinc alloy coated steel sheet is Zn-Al alloy, and the coating composition is 55% Al, 43.3% Zn, and 1.6% Si. Because of its excellent corrosion resistance, this kind of steel is gradually replacing galvanized steel and is widely used all over the world.

Product Advantages

The surface is smooth and has excellent atmospheric corrosion resistance. Its atmospheric corrosion resistance is 2-6 times higher than that of the hot-dip galvanized sheet with the same coating thickness. At the same time, it has high temperature corrosion resistance similar to that of the hot-dip aluminum sheet, aluminum-zinc alloy coated steel sheet It can be used for a long time at a high temperature as high as 315, and a long-term use at a temperature of 500℃~600; it has good water resistance and soil corrosion resistance, and its water corrosion resistance is better than hot-dip galvanized sheet and hot-dip aluminum sheet. Soil corrosion is better than hot-dip galvanized sheet; it has excellent paintability and good processing performance, and its processability and weldability are similar to hot-dip galvanized sheet, can be processed by cold bending, stamping, etc., and has a good appearance .

Application

Zinium Aluzinc Galvalume Steel Coil has both the characteristics of hot-dip galvanized steel sheet and hot-dip aluminum steel sheet. Therefore, where hot-dip galvanized steel sheet is used, aluminum-zinc alloy coated steel sheet can be used, and it can also partially replace hot-dip aluminum steel sheet. It has a wide range of applications, such as roof panels, wall panels, light steel keels, heating radiators, car bodies, fuel tanks, cable armored steel tapes, plastic greenhouses, granaries, shipping containers, household appliances and appliances, Ovens, explosion-proof steel belts, outer covers of air conditioning and ventilation systems, solar water heaters, packaging boxes for chemical products, and color plate substrates, welded pipes, steel windows, cold-formed steel materials in the metallurgical industry, etc., have a very broad application prospect.
