Galvanized Square Tube 78*78*1.4mm

We deeply understand our customers' fundamental need for durability. Anyang Zhongxin's high-strength galvanized welded square tube has a protective system that goes far beyond simple coverage, combining material science with engineering practice. We carefully regulate the temperature and immersion time during the galvanizing process to ensure the formation of a zinc iron alloy layer with a reasonable gradient, which constitutes the first strong line of defense for protection. More valuable is that the zinc layer has the potential for "self-healing": when the surface is accidentally scratched and the steel substrate is exposed, the surrounding zinc will preferentially corrode through electrochemical reactions, continuously protecting the wound from further expansion. This intelligent "sacrificial" protection mechanism enables the product to maintain the integrity of the substrate in changing climates and industrial environments, extending the safety life of the structure several times.…
