The coating structure of Al-Zn alloy coated steel sheet is Zn-Al alloy, and the composition of the coating is 55% Al, 43.3% Zn and 1.6% Si. Because of its excellent corrosion resistance, this kind of steel plate is gradually replacing galvanized sheet and is widely used all over the world.
Smooth surface, excellent atmospheric corrosion resistance, its atmospheric corrosion resistance is 2-6 times higher than that of hot-dip galvanized sheet with the same thickness of the coating; at the same time, it has high temperature corrosion resistance similar to hot-dip aluminized sheet。 Aluminum-zinc alloy coated sheet can be used for a long time at high temperatures up to 315 degrees C, and at temperatures ranging from 500 degrees C to 600 degrees C。 It has good water resistance and soil corrosion resistance。 Its water corrosion resistance is better than that of hot-dip galvanized sheet and hot-dip aluminized sheet, and soil corrosion resistance is better than that of hot-dip galvanized sheet。 It has excellent coating performance and good processing performance。 Its processability and weldability are similar to that of hot-dip galvanized sheet。 It can be processed by cold bending and stamping, and has a good appearance。
Aluminum-zinc alloy coated steel sheet has the characteristics of both hot-dipped galvanized steel sheet and Hot-Dipped aluminized steel sheet. Therefore, where hot-dipped galvanized steel sheet is used, it can partly replace hot-dipped aluminized steel sheet. Its application range is wide, such as roof panel, light steel keel, heating radiator, car body, oil tank, armoured steel strip of cable, plastic. The skeleton materials of greenhouse, granary, container, household appliances and appliances, packing boxes of chemical products, color plate substrates of metallurgical industry, welded pipes, steel windows, raw materials of cold-formed steel, etc., have a very broad application prospect.
The price of aluminium-zinc alloy coated steel sheet is higher than that of ordinary hot-dip galvanized steel sheet, but because the proportion of metal-aluminium is smaller than that of zinc, the proportion of aluminium-zinc alloy coating is only 3.75 kg/dm3, while that of zinc is 7.1 kg/dm3. Therefore, the thickness of aluminium-zinc alloy coating with 150 g/m2 (double side) is equal to that of hot-dip galvanized steel plate with 275 g/m2 (double side) coating weight, which greatly saves the higher price of galvanized steel sheet. Layer metal.
Super corrosion resistance: The corrosion resistance of the product is 6-8 times of that of the general galvanized sheet, which ensures 20 years rust-free in various environments。
High temperature oxidation resistance: no discoloration or deformation occurs at 315 degrees Celsius.
High thermal reflectance: the product's thermal reflectance is higher than 75%, twice as high as that of galvanized sheet.
Easy to process: can meet stamping, shearing, bending and other processing;
Beautiful appearance: Silver-white snowflake pattern, beautiful and beautiful, can be directly used without painting;
Surface spraying: It is a good base material for paint coating. The composite coating of alloy and organic matter can provide more effective protection and prevent corrosion under the organic coating.
