Description
Carbon steel is chemically highly reactive and reacts with oxygen, moisture, acids, and alkalis in the natural environment, leading to oxidation and rust formation. Porous iron wire continuously absorbs moisture and impurities, accelerating internal corrosion and causing wire failure. Hot Dipped Galvanized Wire, on the other hand, has a metallurgically bonded zinc-iron alloy layer. This zinc layer completely encapsulates the wire cross-section, effectively preventing contact between oxygen, moisture, soil, and rainwater, thus completely blocking rust pathways. The surface zinc protective film is water-insoluble, preventing the internal zinc layer from reacting with the external environment and slowing down corrosion in natural conditions. Are you still worried about your iron wire rusting easily and becoming unusable? Then try Hot Dipped Galvanized Wire! Multiple wire diameters are available for you to choose from.

Application
Some rust-proof wires on the market, in pursuit of hardness, suffer from reduced ductility, making them prone to breakage during bending, binding, wrapping, and cutting, thus increasing construction difficulty and delaying the project. Hot Dipped Galvanized Wire, made of low-carbon steel, has excellent ductility and can be easily bent 180° without breaking, and the zinc coating does not peel off. It can be used for construction binding, tying, fixing, and manual shaping. Furthermore, it solves the problems of wire cracking during weaving, the labor-intensive and inefficient nature of manual construction, zinc coating damage after welding, easy rusting of weld points, and the inconvenience of high-altitude and field construction.
Hot-dip Galvanizing Process
Preparation
Degrease the surface of the wire that meets the specifications. Soak it in sulfuric acid or hydrochloric acid to remove oxides and rust. Immerse it in a zinc chloride or ammonium chloride solution to prevent oxidation and enhance zinc wettability. After drying, it is ready for galvanizing. All of this preparation ensures a secure zinc layer.
Hot-dip galvanizing
The treated wire is immersed in a zinc bath at a temperature of 450°C. This dissolves the iron-based surface, forming a zinc-iron alloy layer. Zinc ions then diffuse to form a miscible layer, resulting in a pure zinc layer covering the surface. Throughout the galvanizing process, careful attention must be paid to the bath temperature, immersion time, and pull-off speed; each detail impacts the quality of the zinc layer.
Post-treatment
Cooling begins, either by air or water cooling to solidify the zinc layer. Chromatization is then performed to enhance corrosion resistance. The zinc layer surface is inspected, focusing on uniformity and surface quality.
Hot-dipped galvanized wire solves outdoor usage problems.
When used outdoors, iron wire is exposed to sunlight, rain, snow, and extreme temperatures for extended periods. Ordinary iron wire is prone to rust, while plastic cable ties and nylon ropes are susceptible to aging, becoming brittle, and breaking. Hot Dipped Galvanized Wire, however, offers superior weather resistance, solving the aging problem. The galvanized wire is unaffected by ultraviolet radiation and does not age, become brittle, or fail even after prolonged exposure to sunlight. Even in regions with extreme cold, high temperatures, or large diurnal temperature variations, the wire dimensions remain highly stable, preventing loosening or breakage due to thermal expansion and contraction. Furthermore, continuous exposure to torrential rain does not damage the overall structure of Hot Dipped Galvanized Wire, thus maintaining its continuous corrosion resistance.
