  • The anticorrosion of these raw materials are very different, the use of life is not the same. Cattle fence cold galvanized, also known as electroplating, galvanized little, rust in rain, but the price is cheap, the use of life in 5-6 years. Hot dip galvanizing (low zinc and high zinc) zinc content in 60 grams to 400 grams, the use of life is about 20-60 years, corrosion resistance is general.

  • Before wall plastering, the wall column is connected to the gap construction wire mesh, which can play a certain strengthening and heat preservation effect. The mesh is hung on the interface surface of different grassroots, and the length of each side should meet the requirements of 100mm, so as to prevent shrinkage and cracking caused by different grassroots. Mesh wire diameter can also determine the effect and efficiency of construction, mesh fine laid up convenient soft, high construction efficiency; Of national standard can assure quality, but laid respect is inferior to fine construction fast.

  • When the zinc layer is seriously damaged and endangers the iron matrix, the zinc will produce electrochemical protection on the matrix, the standard potential of zinc is -0.76V and the standard potential of iron is -0.44V. When zinc and iron form microbatteries, the zinc will be dissolved as the anode, and the iron will be protected as the cathode. Obviously, the atmospheric corrosion resistance of hot dip galvanizing is better than that of electric galvanizing.

  • The spring steel wire is made of high carbon and high quality carbon structural steel or carbon tool steel wire rod, and its chemical composition, gas content and non-metallic inclusion must be strictly controlled according to the use of the spring. In order to reduce the appearance of shortcomings and decarbonization layer, the consumption of rod billet to stop surface grinding, if necessary, but also stop peeling.
