AZ150 Galvalume Steel Coil

Galvalume is a product very similar to galvanized steel, with better corrosion resistance (up to three times that of galvanized steel). The excellent performance of galvalume comes from the unique composition of its metal coating (55% Al, 43.4% Zn, 1.6% Si). Applications include use on pre-painted roofing substrates. Galvalume coils are based on cold-rolled full-hard substrates of various specifications, strengths, and thicknesses, and are hot-dipped with a layer of aluminum-zinc coating on both surfaces, integrating high-durability aluminum physical protection and zinc electrochemical protection. features in one. Hot-dip galvanized steel is a type of coated steel. It is made of cold-rolled steel plates of different strengths and thicknesses as the base material and is coated with aluminum-zinc layers on both sides using a hot-dip plating process. Al accounts for about 55% of the coating, Si accounts for about 1.6%, and the rest is Zn. It has both the physical protective properties and durability of Al and the electrochemical protective properties of Zn. Its surface is bright silver, with regular relief patterns, very decorative. Aluzinc az150 galvanized steel sheets are produced using cold rolled rolls of different specifications, and are coated with a galvanized layer on the surface, which can prevent corrosion on the steel surface and extend its service life. The surface is highly decorative bright gray with regular spangles.
