Hot-dip Galvanized Steel Coil
Hot-dip galvanizing is the process of applying a layer of zinc to metal to protect it from corrosion. We can denote it as HDG. The process is divided into three main steps, as follows: surface treatment galvanized examine During the surface preparation step we have to use wires to hang steel items or place on appropriate shelves. Thereafter, the steel goes through three cleaning steps: degreasing, pickling and fluxing. The degreasing step removes dirt from the steel surface. The pickling step removes scale and iron oxide. In a subsequent fluxing step, it removes any other oxides present on the steel surface and forms a protective layer that prevents further oxide formation.
