After being cleaned, cold-drawn, and reaching the desired diameter, the steel wire is put through the annealing process and is divided into A, B, C, and D categories based on the international steel coating classifications. The measuring unit for coating classification is based on grams per square meter, which shows the amount of galvanized coating ranging from the thickest to the thinnest. The galvanized steel wires are used in various applications including fences, mesh, barbed wire, etc.
