Product Description
AZ150 galvalume steel sheet has a coating thickness of 18 microns on one side and 36 microns on both sides. The coating alloy of the steel consists of 55% aluminium, 43.4% zinc and 1.6% silica. This coating of steel acts as a passive barrier to general corrosion. It also helps protect steel from trimmed edges and scratches. AZ150 is a hot-dip aluminum-zinc alloy coated steel. The resulting coating has excellent corrosion resistance and can be used in harsh environments. This combination produces a durable and corrosion-resistant material that can be used in any application with high strength or hardness. Once the sheet is exposed to electrolyte or moisture, another coating may form a galvanic cell. This exposure results in spillage of zinc ions and corrosion protection of the exposed steel. AZ150 aluminized zinc is a high-quality, corrosion-resistant alloy commonly used in the construction and transportation industries. It has strong anti-rust, anti-oxidation and anti-corrosion capabilities, and is an option for those who need to transport items or expose items to severe weather conditions.
