Description

Galvanized iron wire has bright finish with even and attractive zinc coating; thick galvanized layer and strong corrosion resistance; good toughness and firmly adherant to the wire, and can be reused permanently without quality changing.

Galvanized iron wire is a metal product that has been zinc-coated during production. The wire itself possesses excellent toughness and elasticity, and the zinc coating provides corrosion resistance, making it suitable for use in harsh environments or humid areas. Galvanized iron wire is primarily used in construction, agriculture, handicrafts, and weaving, including power engineering bundling, product packaging, and everyday household applications. Its wide range of applications is facilitated by a variety of wire diameters, including 0.4mm, 0.8mm, 1.2mm, 2.0mm, and 5mm. Customization is also possible, greatly satisfying user needs.

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.

Factors affecting zinc layer quality

Surface cleanliness of the raw material: Oil, release agent residue, or scale on the surface can directly lead to pinholes, blistering, or even flaking in the coating, significantly reducing corrosion resistance.

Contamination of the plating bath: Metal ion contamination or organic matter accumulation can damage the coating's density, causing pitting, roughness, and other issues.

Parameter fluctuations: Galvanizing temperature not meeting requirements, pH values outside the optimal range, or excessive sulfuric acid content can make the coating brittle

Zinc coating thickness: Insufficient thickness significantly weakens the coating's protective properties, and insufficient phosphorus content can reduce the salt spray resistance of the electroless nickel coating.
It is recommended that you purchase galvanized Iron wire from a professional manufacturer for optimal performance.
