The coating structure of Al Zn alloy coated steel plate is Zn Al alloy, and the coating composition is 55% Al, 43.3% Zn, 1.6% Si. Because of its excellent corrosion resistance, this kind of steel plate is gradually replacing galvanized steel plate and is widely used all over the world.
The surface is smooth, with excellent atmospheric corrosion resistance, which is 2-6 times higher than that of hot-dip galvanized steel plate with the same coating thickness; at the same time, it has the similar high-temperature corrosion resistance with hot-dip aluminum plate. The aluminum zinc alloy coated steel plate can be used for a long time at a high temperature of 315 ℃ and a long time at a temperature of 500 ℃ ~ 600 ℃; it has good water and soil corrosion resistance Its water corrosion resistance is better than that of hot-dip galvanized steel plate and hot-dip aluminum plate, and its soil corrosion resistance is better than that of hot-dip galvanized steel plate. It has excellent coating property and good processing performance, and its processing and weldability are similar to that of hot-dip galvanized steel plate. It can be processed by cold bending, stamping, etc., and has a good appearance.
Aluminum zinc alloy coated steel plate not only has the characteristics of hot-dip galvanized steel plate, but also has the characteristics of hot-dip galvanized steel plate. Therefore, wherever hot-dip galvanized steel plate is used, aluminum zinc alloy coated steel plate can be used, and it can also partially replace the hot-dip galvanized steel plate, with a wide range of applications, such as roof panel, light steel keel, heating radiator, car body, fuel tank, cable armored steel strip, plastic The frame material of the shed, granary, shipping container, household appliances and appliances, packing box of chemical products and raw materials of color plate base plate, welded pipe, steel window and cold bending section steel in metallurgical industry have a wide application prospect.
The price of aluminum zinc alloy coated steel plate is higher than that of ordinary hot-dip galvanized steel plate, but because the proportion of aluminum to zinc is small, the proportion of aluminum zinc alloy coating is only 3.75kg/dm3, and the proportion of zinc is 7.1kg/dm3, so the thickness of aluminum zinc alloy coating with coating weight of 150g / M2 (double-sided) is equal to that of hot-dip galvanized steel plate with coating weight of 275g / m2 (double-sided), which greatly saves the plating with higher price Layer metal.
Super corrosion resistance: the corrosion resistance of the product is 6-8 times of that of the general galvanized steel plate, and it can keep rust free for 20 years in various environments;
High temperature oxidation resistance: no discoloration or deformation occurs under the high temperature environment of 315 ℃;
High thermal reflectance: the thermal reflectance of the product is higher than 75%, 2 times of that of the galvanized sheet;
Easy processing: it can meet the requirements of stamping, shearing, bending and other processing;
Beautiful appearance: silver white snowflake pattern, beautiful and beautiful, can be used directly without painting;
Surface spraying: it is a good base material for paint coating. The composite coating of alloy and organics can provide more effective protection and prevent corrosion under the organic coating.
