  • Strength of galvanized wire: tensile strength is the great tensile stress that the material can withstand before tensile fracture; Yield strength has two indexes: upper yield and lower yield. It is a process in which the stress does not increase but the deformation continues to occur during the tensile process. When the force value drops for the first time, the major stress is the yield strength, and the yield strength must be less than the tensile strength.

  • Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air, and small in humid air or water containing carbon dioxide and oxygen. A thin film layer of basic zinc carbonate will be formed on the surface, which can delay the corrosion rate of zinc layer. The corrosion resistance of galvanized layer in aqueous solution of acid, alkali and sodium chloride is relatively strong. It is also not resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in Marine atmospheres; In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded.

  • Electric welding net welding after galvanized is after the completion of the welding and then cold galvanized or hot galvanized; After the first galvanized welding is to change the wire welding mesh, welding can be seen after the completion of the welding spot; The two processes are different prices are also very different, the cost of the first plating after welding is low, the surface is smooth, and the cost of the first welding after plating is higher, not easy to rust.
