Surface treatment
1. The surface treatment of steel grating plate (also known as steel grid plate) has three ways: hot dip galvanizing, painting and no treatment.Hot dip galvanizing is recommended for surface treatment.
2. Hot dip galvanizing is the steel grating plate (also known as steel grid plate) parts immersed in molten zinc bath, forming zinc coating on its surface process and method.The thickness of flat steel is in the range of 3 ~ 5mm, and the average thickness of galvanized layer is about 70μm.In the range of pH 6 ~ pH 12.5, the surface of the galvanized layer forms a stable protective film with good corrosion resistance.
