Products Description
The galvanized layer on the surface of galvanized square pipe has strong protective effect and strong corrosion resistance. The entire structure is made of zinc, forming a dense quaternary crystal. This crystal forms a barrier on the steel plate, thus effectively preventing corrosion factors from penetrating. Corrosion resistance comes from the strong protective barrier layer of zinc. When zinc provides sacrificial protection on trimmed edges, scratches, and scratched parts of the coating, the zinc forms an insoluble oxide layer and plays a barrier protective function.
