Engineered for the rigorous demands of the manufacturing sector, our Aluzinc steel plate provides a superior alternative to traditional galvanized steel. This Aluzinc steel plate is defined by its specific metallic coating—55% aluminum, 43.4% zinc, and 1.6% silicon—which is metallurgically bonded to the steel substrate via a hot-dip process . The result is a product that combines the strength of steel with the barrier protection of aluminum and the cathodic protection of zinc. In comparative salt-spray tests, this Aluzinc steel plate demonstrates corrosion resistance up to three times greater than conventional zinc-coated sheets, ensuring the longevity of components in HVAC, electrical enclosures, and automotive parts .
Manufacturers will appreciate the robust mechanical properties and workability of the Aluzinc steel plate. It is available in a wide range of structural and cold-forming grades—such as DX51D+AZ, S250GD+AZ, and S550GD+AZ—allowing for precise specification based on strength requirements . Despite its tough coating, this Aluzinc steel plate exhibits excellent adhesion and flexibility, making it ideal for profiling, bending, and deep drawing without flaking or micro-cracking. It also supports reliable welding and cutting, facilitating seamless integration into existing production lines for applications like control cabinets, computer casings, and industrial ovens .
Finally, the Aluzinc steel plate offers exceptional surface properties that enhance both the manufacturing process and the final product. Its heat reflectivity is superb, withstanding temperatures up to 315°C, which is critical for components near heat sources like dryer drums and boiler casings . The surface is also highly receptive to paint and can be supplied with chemical passivation or anti-fingerprint treatments to maintain a clean, high-quality appearance during assembly . By choosing this Aluzinc steel plate, industries benefit from a cost-effective material that delivers extended service life, reduces maintenance, and ensures product reliability across countless applications .
