Alu-zinc hot diped galvalume steel coil for corrugated steel sheet is a premium material used in the manufacture of corrugated steel sheets, and its properties and performance make it an ideal building material choice. The following is a detailed description of this product.
It consists primarily of Aluminum, Zinc and small amounts of Silicon, which are solidified at high temperatures to form a dense alloy structure. This alloy structure gives the coil excellent physical and chemical properties. This product has the following characteristics. First and foremost, it has excellent corrosion resistance due to its Aluminum-zinc alloy properties. When the zinc layer is abraded, the Aluminum forms a dense protective layer of Aluminum oxide, which effectively prevents further attack by corrosive substances. This corrosion resistance far exceeds that of pure galvanized coils, ensuring the long-term stability of corrugated steel sheets in harsh environments. Secondly, it has excellent heat resistance and is able to withstand high temperature environments up to more than 300 degrees Celsius. This makes it particularly suitable for applications that need to withstand high temperatures, such as chimney pipes and ovens. Thirdly, it has a very high thermal reflectivity, twice that of galvanized steel. Therefore, it is often used as an insulating material, effectively reducing heat transfer and improving the energy efficiency of corrugated steel sheets. Since the density of Al-Zinc alloy is less than zinc, the area of Al-Zinc coils is more than 3% larger than that of galvanized steel coils for the same weight and coating thickness, which makes it more economically efficient. Fourthly, it has good processing performance and can be stamped, sheared, welded and other operations to meet various processing needs in the manufacturing of corrugated steel sheets. Fifth, it has a long service life, up to 25 years under normal conditions. This is due to its excellent corrosion resistance and durability, which allows corrugated steel sheets to maintain their functionality and aesthetics over time in a variety of environments. Sixth, economical efficiency: since the density of 55% Al-Zn is smaller than the density of Zn, the Aluminum-zinc-plated steel sheet is more than 3% larger than the area of the plated steel sheet when the weight is the same and the thickness of the gold-plated layer is the same.
To sum up, Alu-zinc hot diped galvalume steel coil is ideal for corrugated steel sheet fabrication due to its excellent corrosion resistance, heat resistance, heat reflectivity and economy. Not only does it provide long-lasting, consistent performance, but it also offers good processability and economy, providing strong support for corrugated steel sheet applications in construction, industry, and other fields.
