Aluminized steel plate: Aluminized steel plate is a steel plate coated with aluminum-silicon alloy, in which the aluminum content is 90% and the silicon is 10%.
Aluminized zinc plate: The surface coating of aluminized zinc plate is composed of 55% aluminum, 43.5% zinc and a small amount of other elements.
Galvanized sheet: Galvanized sheet refers to a steel plate coated with a layer of zinc on the surface.
The difference between galvanized sheet and galvanized sheet:
55% aluminum-zinc alloy coated galvanized steel sheet has better corrosion resistance than galvanized steel sheet of the same thickness when exposed to the same environment on both sides. The 55% aluminum-zinc alloy coated aluminum-zinc steel sheet not only has good corrosion resistance, but also the color-coated products have excellent adhesion and flexibility.
The main difference between galvanized sheet and galvanized sheet is the difference in coating. A layer of zinc material is evenly distributed on the surface of galvanized sheet, which acts as an anodic protection for the base material, that is, alternative corrosion protection for zinc materials. In addition to the use of the base material, the base material inside can only be damaged when the zinc is completely corroded.
The surface coating of the aluminized zinc sheet is composed of 55% aluminum, 43.5% zinc and a small amount of other elements. The surface of the aluminized zinc coating is a honeycomb structure under the microscopic view, and the "honeycomb" made of aluminum contains zinc. In this case, although the aluminum-zinc coating also plays the role of anode protection, on the one hand, because the zinc content is reduced, on the other hand, the zinc material is wrapped in aluminum and is not easy to electrolyze, so the role of anode protection is greatly reduced. Therefore, once aluminum is plated The zinc plate is cut, and it will rust soon when the cut edge is basically lost and protected. Therefore, the aluminum-zinc plate should be cut as little as possible. Once cut, the edge can be protected with anti-rust paint or zinc-rich paint. The service life of the plate is extended.
