What are the technical requirements for the zinc layer of hot-dip galvanized steel grating plates?

Galvanized steel grating plates have high requirements for galvanizing technology, and the zinc layer cannot be too thin or too thick. Next, we will explain in detail the requirements of galvanized steel grating plates for the galvanized layer.

If the zinc layer on the steel grating is too thin, it will lead to the appearance of leakage plating in the pores of the steel grating, resulting in a decrease in the anti-corrosion performance of the steel grating and affecting its service life.

It is also not good for the zinc layer on the steel grating to be too thick. A thick zinc layer can easily cause the zinc layer to fall off, seriously affecting the quality of the steel grating.

Before galvanizing the steel grating, it is also necessary to ensure that the pickling of the steel grating is thorough and there is no residual iron oxide, otherwise the galvanized layer cannot adhere perfectly to the surface of the flat steel.
