  • Cold galvanizing, also called galvanizing, is the steel wire placed in the plating tank, through the one-way current to make the metal surface slow galvanized, zinc is slow, and the thickness is only one tenth of hot dip galvanizing, zinc layer is thin, so the rust resistance is not good, placed in the outdoor usually a few months will rust, applied in the outdoor generally in the plastic coating.

  • The composition of hot dip galvanizing layer is composed of hot dip galvanizing layer, which is composed of iron zinc alloy between iron matrix and surface pure zinc layer. The shape of the workpiece is formed by the iron zinc alloy layer in hot dip, so that the iron and pure zinc layer touch outstanding. When the iron workpiece is immersed in a molten zinc solution, the initial zinc and iron (body) are formed at the interface. This is a crystal made up of zinc atoms in the solid metal iron. When two metal atoms are fused together, the gravitational force between the atoms is very small.

  • Galvanized also has several different methods, the so-called hot dip galvanizing is put racing in the zinc bath, need to clean them on metal, which ensures that formed between metal and coating adhesive, after cleaning, the matrix metal is dissolved, to clear any residual oxides of residue and then immerse the substrate metal heating liquid zinc, and metallurgical bonding is formed.
