  • During this process, each time the wire is pulled over, the surface hardens due to the high friction temperature. So basically every time you pull it you have to annealing it in the furnace. On the one hand, it is to reduce the surface hardness. On the other hand, during the process of wire pulling, only the surface is deformed, and the center is unchanged. So there’s a lot of stress inside. Therefore, it is necessary to rely on annealing to eliminate the internal stress, so that the wire becomes soft again to eliminate the stress before being drawn again.

  • Galvanized iron wire is divided into hot galvanized wire and cold galvanized wire, the use of low carbon steel wire processing, after drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. Good toughness and elasticity, zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Galvanized iron wire can be cut off the tie wire used in the building, the length of 20cm 30cm 40cm, can be cut off according to requirements.

  • Usually, there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment is easier to rust than dry environment, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the customized corrosion of hexagonal guardrail and extend the service life of the product.

  • In addition to these reasons, we should pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of galvanized layer.

  • The corrosion resistance of hot dip galvanized is much higher than that of cold dip galvanized, also known as electric dip galvanized. Hot wire will not rust for several years, cold galvanized will rust within three months. The cold galvanizing process is used to protect the metal from corrosion, for which the coating of zing filler is used,which is applied to the protected surface by any of the coating methods and dried to form a zinc filler coating with a zinc content (up to 95%) in THE DRY coating.
