Hard black galvanized iron wire is made of low carbon steel wire directly drawn by drawing machine. The primary characteristics of hard black galvanized iron wire are high hardness and bright appearance. Primary use for welding hanger, umbrella, metal mesh, basket, basket and other metal products. Soft black galvanized iron wire is made of low carbon steel wire after annealing and softening, and then cold drawn. The primary feature of soft black galvanized iron wire is good flexibility, slightly higher hardness, bright appearance. Mainly used for metal mesh weaving process, electric welding mesh, welding process products.

Galvanized wire in acid, alkali, sodium chloride aqueous solution of poor corrosion resistance, in the atmosphere containing carbon dioxide and hydrogen sulfide, as well as Marine atmosphere is not corrosion resistance. In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded. Galvanized wire and general wire is very different, general wire is cheap, and because the iron is not very stable, easy to rust in the wet place, so the stability is not very good, the life is not very long.
