Materials Of Coated Steel Wire
The materials of coated steel wire mainly include pure zinc, hot-dip galvanizing, electro-galvanizing and zinc-10% aluminum-rare earth alloy.
Pure zinc-coated steel wire: This kind of steel wire has good toughness and elasticity, and the maximum zinc coating can reach 300 grams/square meter. It has the characteristics of thick coating and strong corrosion resistance.
Hot-dip galvanized steel wire: Hot-dip galvanized steel wire is a variety of high-quality medium-carbon steel or high-carbon steel that is pickled, phosphated, and wire drawn before being hot-dip galvanized. The zinc layer of hot-dip galvanizing is thicker and has better corrosion resistance.
Electro-galvanized steel wire: The zinc layer of electro-galvanizing is thinner and has relatively poor corrosion resistance, but the corrosion resistance can be improved by increasing the thickness of the zinc layer.
Zinc-10% Aluminum-Rare Earth Alloy Coated Steel Wire: This type of steel wire is an upgraded product of pure zinc coating, with the main components being aluminum (9-12%), lanthanum (0.035%), cerium (0.035%), and the rest being zinc. Its corrosion resistance is 1 to 3 times higher than pure zinc, and even 3 to 8 times higher in some cases.
