  • 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.

  • There are two kinds of electrochemical protection. One is to connect a piece of metal that is slightly more vivid than it. For example, ships and ships will be inlaid with zinc blocks. The second is to connect the negative terminal of the power supply, such as iron and steel river locks are often connected with the negative terminal of the power supply, through the negative terminal. Its methods include: metal cover film such as electroplating, organic coating such as paint, transformation layer such as orchid or black, new elements to change the metal structure.

  • When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.
