Color Stability of Galvanized Steel Grating

Galvanized steel grating is commonly seen in white color. However, before undergoing the galvanization process, the steel grating is not white. It is the result of galvanization that gives it the silver-white appearance.

The galvanization process aims to achieve a smooth surface and prevent rust. The color of galvanized steel grating is typically silver-white. Some may also be coated with paint, resulting in colors like blue. The authentic nature of galvanized steel grating mainly depends on the thickness of the galvanized coating, with a minimum requirement of 70μm for hot-dip galvanized steel grating and 10μm for cold-dip galvanized steel grating. The quality of galvanization affects the price of galvanized steel grating.
