ASTM A792 Chinese galvalume coil factory g550 az150 and more specifiations

Short Description:

Galvalume steel coils is Zn-Al alloy coated, and the coating composition is 55% Al, 43.3% Zn, and 1.6% Si. It has excellent corrosion resistance, and gradually replacing galvanized steel and is widely used all over the world.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.

The price of Zinium Galvalume Steel Coils is higher than that of ordinary hot-dip galvanized steel sheet, but because the specific gravity of aluminum is smaller than zinc, the specific gravity of aluminum-zinc alloy coating is only 3.75kg/dm3, while the specific gravity of zinc is 7.1kg/dm3, so the coating weight of the aluminum-zinc alloy coating of 150g/m2 (double-sided) is the same as that of the hot-dip galvanized steel plate with the coating weight of 275g/m2 (double-sided), which greatly saves the more expensive coating metal.

Precautions for use
Storage of galvalume coils: It should be stored indoors such as warehouses, kept dry and ventilated, and should not be stored for a long time in an acidic climate. When storing outdoors, it is necessary to prevent rain and avoid condensation caused by oxidation stains.
Transportation of galvanized coils: avoid external impact, SKID should be used to support steel coils on transportation tools, reduce stacking, and take rain-proof measures.
Galvanized coil processing: COILCENTER needs to use the same lubricating oil as aluminum plate when cutting. When drilling or cutting galvanized steel sheets, it is necessary to remove scattered iron filings in time.
