Galvanized Steel Wire: Two Processes Available, Multiple Advantages for Adaptation

1. Hot-Dip Galvanized Steel Wire (Long-Lasting Anti-Corrosion Type)A 45-300μm zinc layer is formed via the hot-dip galvanizing process, featuring strong adhesion and resistance to peeling. It offers 10-30 years of outdoor corrosion resistance, withstanding wind, rain, humidity and acid-base conditions, and is suitable for long-term outdoor scenarios such as photovoltaic brackets, bridge guardrails and outdoor fences.
2. Cold-Galvanized Steel Wire (Economical and Practical Type)A 3-15μm zinc layer is attached through electroplating, presenting a bright and uniform surface. It provides 3-12 months of corrosion resistance for indoor/short-term use at a lower cost, and is applicable to scenarios like building steel bar binding and handicraft production.

Three Core Selling Points to Solve Usage Pain Points

1. Strong Anti-Corrosion & Rust-ProofThe zinc layer forms a protective barrier that isolates air and moisture, increasing the service life by more than 10 times compared to ordinary black iron wire and reducing replacement costs.
2. High Strength & Easy ProcessingThe substrate has a tensile strength of 300-600MPa, which can be bent, welded, woven into mesh and easily cut, adapting to diverse processing needs.
3. Customizable Multiple SpecificationsDiameters range from 0.8-12mm for selection, and lengths support 100m/200m per roll or custom cutting, meeting the needs of batch engineering and small-batch use.

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.
