3 mm Steel Wire Galvanized Iron Wire for Construction & Fencing

What Is 3 mm Steel Wire Galvanized Iron Wire and What Is It Used For?

3 mm steel wire galvanized iron wire is a highly versatile material widely used in construction, agriculture, manufacturing, and various industrial applications. It is produced from high-quality low-carbon steel wire, then fully coated through either hot-dip galvanizing or electro-galvanizing. The zinc layer acts as a protective shield, preventing oxidation and rust even under long-term outdoor exposure.

This size—3 mm diameter—offers an ideal balance of tensile strength and workability. It is firm enough for reinforcement, fencing, framework fabrication, and wire mesh production, yet flexible enough to bend or twist during installation. Many buyers choose this specification because it performs reliably across fencing projects, greenhouse structures, vineyard trellises, and binding tasks on construction sites.

Factories also use 3 mm steel wire galvanized iron wire to manufacture welded wire mesh panels, chain link mesh selvage wire, barbed wire cores, and nail production. Its consistent diameter and smooth galvanized surface make it easy to feed through machines without causing jams or abrasion.

When used outdoors, the zinc coating protects the steel core from moisture, soil acidity, and temperature changes. This greatly extends its service life—often several years longer than uncoated steel wire—making it a cost-effective option for both homeowners and industry professionals.

For customers requiring custom tensile grades, coil weights, or zinc coating thickness, manufacturers like us can provide tailor-made specifications to meet different project requirements.

FAQ

Q1. Is 3 mm galvanized iron wire suitable for outdoor use?
Yes. The zinc coating protects the steel core from rust, making it ideal for long-term outdoor applications.

Q2. What is the difference between electro-galvanized and hot-dip galvanized?
Hot-dip offers thicker zinc coating and stronger corrosion resistance, while electro is smoother and lower cost.

Q3. Can 3 mm galvanized wire be used for welded mesh?
Absolutely. It is commonly used for 50×50 mm, 75×75 mm, and 100×100 mm welded wire mesh panels.

Q4. Do you offer custom coil weights or tensile strength?
Yes. Coil size, zinc thickness, and tensile grade can all be customized for bulk orders.
