Difference Between Hot-Dip and Electro-galvanized Steel Sheets

Anti-corrosion

Generally, the thickness of hot-dip zinc coating is more than 35 μm, or even as high as 200 μm. While the electro-galvanized zinc layer is only 5~15 μm in thick. So the former steel sheet is much more corrosion resistant than the latter one.

Hot-dip galvanizing : it is an effective metal anti-corrosion method, mainly used in metal structure facilities in various industries. The rust-removed steel parts are immersed in a molten zinc solution at about 500°C to attach a zinc layer to the surface of the steel parts to achieve the purpose of corrosion protection.

Testing

Over the years, we have worked hard to promote and realize the modernization of Galvanized Steel sales, and actively cultivated and enhanced the ability of employees' independent innovation. All-round renovation and upgrade of the original business site, facilities and equipment, and modern computer management. Hope to establish long-term partnerships and win market reputation.
