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.

Product Details

The hot-dip pure zinc process can generate spangles of different sizes. The spangles affect the surface sensory, but do not affect the corrosion resistance.
