What are the consequences if the steel grating is not hot zinc treated

If the steel grating is not surface treated, it will become what people call black flakes, and there will be no consequences. However, its service life will be far less than that of hot-dip galvanized steel grating. If the steel grating is not galvanized, it will quickly oxidize and rust. If the welds are severely rusted, the welds will open. The remaining flat steel will also reduce its thickness after a long period of rust, and the corresponding bearing capacity will be reduced. Steel grating is also divided into cold galvanizing and spray painting. Since steel grating generally needs to be used for a long time, cold galvanizing and spray painting are not suitable for steel grating. Steel grating made of cold galvanizing and spray painting works well in places where the environment is particularly dry and people do not often step on the steel grating. It is inexpensive, but has great limitations. Therefore, it is recommended to buy steel grating with hot-dip galvanizing, which is better for long service life. Although it is a bit more expensive, it is still a very economical choice.
