Galvanized wire can be divided into hot-dip galvanized wire and electro-galvanized wire, the difference between the two is the way of zinc and the amount of zinc on it.
Hot-dip galvanizing is to soak the steel wire in the molten zinc solution. The zinc plating on the hot-dip galvanizing is fast. The rust-proof performance of the zinc layer is very good, but the zinc is uneven and the surface is dark, and the life of hot-dip galvanizing can reach 20 years. we will briefly introduce the use of the wire. Our company can provide electro galvanized wire you can understand.
Electro-galvanizing is to place the steel wire in the plating tank, and the metal surface layer is slowly galvanized by the unidirectional current. The zinc plating on the electroplating zinc is relatively slow, and the thickness is only one-tenth of that of hot-dip galvanizing. The zinc layer is thin and the rust-proof property is obtained. Not so good, it will usually rust in a few months when it is placed outdoors, and it will be coated in the outdoors.
Hot-dip galvanizing is immersion plating in a hot melted zinc bath. The production speed is fast, the coating is thick but uneven, and the market allows a minimum thickness of 45 microns and a maximum of 300 microns or more. Hot-dip galvanizing consumes more zinc metal, forms an infiltrated layer with the base metal, and has good corrosion resistance. Hot-dip galvanizing can be maintained for several decades in an outdoor environment. Electrogalvanizing is slow in production, uniform in the coating, thin in thickness, usually only 3-15 microns, bright in appearance and poor in corrosion resistance, and it will rust in a few months. Relative to hot-dip galvanizing, electro-galvanized production costs are lower.
