Galvanized Wire: Dual Processes & Customizable Solutions

Two Core Galvanizing Processes

1. Hot-Dip Galvanized Wire (Long-Lasting Anti-Corrosion Grade)

• Process: Steel wire is fully immersed in molten zinc, forming a 45-300 μm zinc layer with strong adhesion and anti-peeling properties.

• Performance: Boasts 10-30 years of outdoor corrosion resistance, withstanding wind, rain, humidity, and acid-base environments.

• Applications: Perfect for long-term outdoor use in photovoltaic brackets, bridge guardrails, outdoor fences, breeding cages and more.

2. Cold-Galvanized Wire (Economical & Practical Grade)

• Process: Electroplating technology deposits a 3-15 μm zinc layer, creating a bright, uniform surface finish.

• Performance: Offers 3-12 months of corrosion resistance for indoor or short-term use, at a more economical cost point.

• Applications: Ideal for building steel bar binding, product strapping, temporary isolation nets, handicraft production and similar scenarios.

Three Core Selling Points to Resolve Usage Pain Points

1. Superior Anti-Corrosion & Rust PreventionThe zinc layer acts as a protective barrier, blocking air and moisture from the steel substrate. This extends the wire’s lifespan by over 10 times compared to ordinary black iron wire, while cutting down on the cost of frequent replacements.
2. High Strength & Easy ProcessabilityWith a tensile strength of 300-600MPa, the base material can be bent, welded, woven into mesh, and easily cut to fit a wide range of processing requirements.
3. Fully Customizable SpecificationsChoose diameters from 0.8-12mm, and select lengths of 100m/200m per roll or custom-cut lengths. This flexibility meets the demands of both large-scale engineering projects and small-batch applications.

FAQ：

Q1: How to choose between hot-dip galvanized wire and cold dip galvanized wire?

A1: For long-term outdoor use (such as fences and photovoltaic brackets), choose hot-dip galvanized wire, which is corrosion-resistant for 10-30 years; Cold galvanized wire is selected for indoor/short-term use (such as steel bar binding and packaging), with low cost and corrosion resistance of 3-12 months.

Q2: Can the diameter and length be customized? What are the commonly used specifications?

A2: Support customization. The diameter is usually 0.8-12mm, and the default length is 100m/200mm per roll. Batch cutting can be done as needed, please contact customer service in advance.

Q3: How to determine the quality of galvanized wire?

A3: Check the appearance for any missing plating or bubbles; Bend the zinc layer 180 ° without peeling off; Batch procurement requires a quality inspection report to confirm that the coating thickness meets the standard.

Q4: Can it be used by the seaside or in chemical plants?

A4: It is recommended to choose zinc aluminum magnesium alloy coated wire, which has 3-5 times higher corrosion resistance than ordinary hot-dip galvanizing; Due to limited budget, thick hot-dip galvanized wire can be selected, paired with anti rust paint.

Q5: How to store unused items?

A5: Place in a dry and ventilated place, with wooden pallets not directly falling to the ground; Unused sealed plastic film, a small amount of white spots can be wiped clean with a dry cloth.
