Hot-dip galvanizing

It is a form of galvanization. It is a process of coating steel grating with a thin zinc layer. By passing the metal through a molten bath of zinc, the average coating thickness is 70μm when steel bards range from 3mm to 5mm in thickness.

Painting

It is also a good way to get surface protective film. Coating thickness depends on the customer's choice.
