The surface coating of the aluminized zinc plate is composed of 55% aluminum, 43.5% zinc and a small amount of other elements. The surface of the galvanized coating is a honeycomb structure, and the "honeycomb" In this case, although the galvanized coating also plays the role of anode protection, but on the one hand due to the reduction of zinc content on the one hand because the zinc material is not easily electrolyzed by aluminum so the role of anode protection greatly reduced, so once the aluminum The zinc plate is cut and the corrosion will soon be corroded in the case where the cut edge is substantially lost. Therefore, the galvanized sheet should be cut as little as possible. Once the edge of the anti-rust paint or zinc-rich paint is applied after cutting, The service life of the sheet is prolonged.

The surface of the galvanized sheet is more beautiful than that of the galvanized sheet, and the cost of the galvanized sheet is higher than that of the galvanized sheet. The cost of the small zinc flower is higher than that of the large zinc flower. In the air damp rain and more cities, once the galvanized sheet of a certain point of rust if not timely measures to take place slowly rusty will eventually be the last and even the entire board; and galvanized sheet even if a point of rust Will not spread.
