Difference between galvanized sheet and galvanized sheet

[China Aluminum Network] The difference between galvanized and galvanized steel is mainly due to the difference in plating. The surface of galvanized sheet is evenly distributed with a layer of zinc material, which plays a role of anode protection for the parent metal, that is, zinc. The alternative corrosion of the material protects the use of the base metal. Only when the zinc is completely corroded can it damage the parent metal. The surface coating of the galvanized steel sheet is composed of 55% aluminum, 43.5% zinc and a small amount of other elements. At the microscopic level, the surface of the galvanized zinc coating is a honeycomb structure, and the “honeycomb” made of aluminum contains zinc. In this case, although the galvanized zinc coating also plays an anodic role, on the one hand, due to the reduction of the zinc content, on the one hand, since the zinc material is not easily electrolyzed by the aluminum, the role of the anodic protection is greatly reduced, so once the aluminum is plated The zinc plate is cut, and the rust will soon be rusted if the severed edge is substantially lost. Therefore, the galvanized steel plate should be cut as little as possible. Once the cutting is applied, the anti-rust paint or zinc-rich paint is used to protect the edges. The service life of the plate is extended. The surface of the galvanized steel sheet is more beautiful than that of the galvanized sheet. At the same time, the price of the galvanized sheet is more expensive than that of the galvanized sheet. The price of the small galvanized sheet is also more expensive than that of the large galvanized sheet. In a city where there is a lot of humid and rainy water, once a point of galvanized steel sheet is rusted, if it is not taken in time, the place where the rust will slowly grow will be larger and later than the entire surface; and even if the galvanized sheet is rusted at some point, Nor will it spread.
