Advantages of galvanized aluminum zinc steel coils

In today's industrial manufacturing field, aluminum zinc coated steel coils are rising strongly and becoming the "favorite" of many industries due to their outstanding performance.
The most outstanding feature is its exceptional corrosion resistance. The coating of aluminum zinc coated steel coil is formed by the solidification of 55% aluminum, 43.4% zinc, and 1.6% silicon at a high temperature of 600℃. Its unique, dense quaternary crystalline structure endows it with extraordinary protective ability. When zinc is worn out daily, aluminum can quickly oxidize, forming an indestructible, dense aluminum oxide film, like a loyal guardian, blocking corrosive substances from further corroding the internal steel. Data shows that its normal service life can reach up to 25 years, three times that of pure galvanized sheet. Whether in humid and rainy coastal areas or heavily polluted inland factory areas, aluminum zinc coated steel coils can guarantee 20 years of rust-free operation, providing a solid guarantee for the long-term stable operation of various facilities.
The heat resistance performance is also outstanding. It can easily withstand a high-temperature environment of 315℃, similar to the high-temperature oxidation resistance of aluminum-plated steel plates, making it highly favored in the manufacturing of high-temperature equipment such as chimney pipes and industrial ovens. At the same time, its thermal reflectivity is as high as 75%, twice that of galvanized steel plate. This characteristic makes it an excellent insulation material, widely used in building exterior walls and roofs, which can effectively reduce indoor energy consumption and achieve energy conservation and emission reduction.
In terms of craftsmanship, aluminum zinc coated steel coils can meet complex processing requirements such as stamping, shearing, and bending. They have excellent adhesion to paint and can be directly painted without tedious pretreatment and weathering treatment, greatly improving production efficiency and preventing rust under organic coatings. Its appearance presents a unique silver white snowflake pattern, which is beautiful and elegant, adding a lot of aesthetic value to the product.
From an economic perspective, due to the lower density of 55% AL Zn compared to Zn under the same weight and coating thickness, aluminum zinc coated steel plates have an area that is more than 3% larger than galvanized steel plates. This means that companies can obtain more usable area when purchasing the same weight of plates, effectively reducing raw material costs.
Based on the above advantages, aluminum zinc coated steel coils have shown great potential in industries such as construction, home appliances, and automobiles. In the field of architecture, light steel structure villas use aluminum zinc coated steel coils, which are not only sturdy and durable, but also maintain long-term beauty; In the home appliance industry, the shell of high-end electronic products is made of aluminum zinc coated steel coils, which enhances the texture and protective performance of the products; In automobile manufacturing, some components are made of aluminum zinc coated steel coils, which enhances the durability of the car in complex environments. With the continuous advancement of technology, aluminum zinc coated steel coils will undoubtedly shine in more fields, injecting new vitality into the development of the industry.
