Galvanized Steel Wire
Galvanized Steel Wire
When the zinc is in a liquid state, the hot dipped galvanized steel wire undergoes quite complex physical and chemical reactions to not only coat the steel with a thicker layer of pure zinc, but also generate a zinc-iron alloy layer.
Preservative
Hot dip galvanized wire has a thick and dense layer of pure zinc covering the surface of the steel, which can avoid the contact of the steel matrix with any corrosive solution and protect the steel matrix from corrosion.
Ductility
Because zinc has good ductility and its alloy layer adheres firmly to the steel base, hot dip parts can be cold punched, rolled, drawn, bent, etc. without damaging the coating.
Mechanical
After hot-dip galvanizing, it is equivalent to an annealing treatment, which can effectively improve the mechanical properties of the steel matrix, eliminate the stress during forming and welding of steel parts, and is conducive to turning steel structural parts.
The surface of hot dip galvanized wire is bright and beautiful. It has an iron-zinc alloy layer, which is densely bonded and exhibits unique corrosion resistance in marine salt spray atmosphere and industrial atmosphere.
The galvanized layer of galvanized wire is formed by zinc in a high-temperature liquid state in three steps:
The surface of the galvanized wire base is dissolved by the zinc liquid to form a zinc-iron alloy phase layer;
The zinc ions in the alloy layer further diffuse to the matrix to form a zinc-iron miscibility layer;
The surface of the alloy layer is surrounded by a zinc layer.
The application of zinc coated steel wire has also expanded with the development of industry and agriculture. Therefore, galvanized steel wire is widely used in industry (such as chemical equipment, petroleum processing, ocean exploration, metal structures, power transmission, shipbuilding, etc.), agriculture (such as sprinkler irrigation, heated rooms), and construction (such as water and gas transmission, wire covers, etc.). Pipes, scaffolding, houses, etc.), bridges, transportation, etc., it has been widely used in recent years. Because galvanized carbon Steel wire rod has the characteristics of beautiful appearance and good corrosion resistance, its application range is becoming more and more extensive.
