  • The steel mesh improves shock resistance and crack resistance. The longitudinal and transverse steel bars of the welded steel mesh constitute a network structure. Therefore, the bond anchorage between the steel mesh and concrete is good, and the load distribution is uniform, which significantly improves the earthquake resistance and crack resistance of the reinforced concrete structure. According to the practice test, the cracks of welding net are reduced by more than 75% than that of manual binding net. Greatly reduce the unnecessary cost of the construction process, shorten the construction cycle, the use of steel wire mesh is simple and convenient, easy to transport.

  • After annealing, iron wire will become softer and more flexible. Iron is a more active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in dry air, its production cost is low, the use and scale is relatively wide, better protective function, so it is an important material for steel parts used in strict working environment.

  • In the use of time do not need to carry out daily maintenance and maintenance, not only can save a lot of time, but also can reduce the cost, but also has good stability, strong corrosion resistance, greatly prolong the service life. According to the different process is divided into different kinds, can be selected according to their own needs, has good flexibility and elasticity. The main role of annealing wire is to control its degree of hardness and softness. When making annealing wire, it is made of steel wire.

  • The wire rod should be normalized or soxhlet processed, instead of spheroidal annealing for standard large ones. Soxhlet process is widely used in the heat treatment of the center, especially the products before drawing. Avoid decarbonization during heat treatment. After heat treatment, sulfuric acid or hydrochloric acid pickling is used to remove iron sheet. The coating (see smooth carrier) can be dip-lime, phosphating, borax treatment or copper plating.
