Galvanised Steel Wire 3mm

Galvanised steel wire 3mm is made from 3mm diameter low-carbon or medium-carbon steel wire, coated with a zinc layer through hot-dip galvanizing or electroplating. It combines the strength and toughness of steel wire, while the zinc layer effectively isolates air and moisture, enhancing corrosion resistance. It is widely used in applications such as building lashing, agricultural greenhouse construction, wire mesh weaving, handicraft production, and light traction, offering high cost-effectiveness and practicality. Wanzhi Steel stocks a large inventory of 3mm galvanized wire and offers a variety of coil weights and packaging options. If interested, please contact us for more information.

Production Process

Feature

• Strong Corrosion Resistance: The zinc coating on the surface isolates air and moisture, slowing oxidation and rusting, making it suitable for humid or outdoor environments.
• Low Cost: Compared to stainless steel, galvanized wire is more affordable and cost-effective, making it suitable for large-scale use.
• Moderate Strength: The 3mm diameter offers both flexibility and load-bearing strength, allowing for bendability and resistance to breakage, meeting most bundling and support needs.
• Easy Processing: Easy to cut, bend, and weld, it can quickly create structures such as fencing and mesh without the need for complex tools.
• Smooth Surface: The galvanizing process creates a smooth surface, reducing friction damage and making it suitable for applications requiring frequent movement or adjustment.
• Retained Conductivity: The thin zinc coating minimizes the conductivity of the metal substrate, making it suitable for electrical grounding or anti-static applications.

Applications

Construction and Decoration

It can be used for tying steel reinforcement bars and securing wall tie bars during construction, as well as reinforcing ceiling keels and securing pipelines during renovation. It can also be used as weft or edge reinforcement to weave various protective and isolation netting. It can also be used as the core of barbed wire and razor wire.

Agriculture and Animal Husbandry

It can be used to secure greenhouse film and trellis structures during agricultural greenhouse construction; in horticulture, it can be used to tie fruit tree branches and secure vines such as grapevines, cucumbers, tomatoes, and climbing flowers. It can also be used in chicken coops, sheep pens, and farm fencing.

Wire Mesh and Protection

It can be used to weave lightweight protective netting, such as balcony netting, small equipment protective covers, and livestock netting, such as chicken and rabbit enclosures. It can also be processed into wire mesh sheets for filtration, such as simple liquid filtration and impurity screening.

Crafts and Everyday Uses

Handmade metal crafts, such as wire ornaments and holiday decorations, are used in everyday life for bundling items such as packaging reinforcement, organizing miscellaneous items, and making simple small household appliances, such as spring cores for sofas and mattresses, lounge chairs, and hanging basket frames.

Industrial Auxiliary Uses

Securing parts and wrapping protective pipes in small machinery manufacturing; also used as temporary traction ropes for small equipment and conveyor belt edge positioning ropes. It can also be used to bundle heavy goods such as steel, wood, and pipes, and to make bag sealing lines.

Select the zinc layer according to the use

• General Use: 15-150 g/m², used for bundling, braiding, and general fastening. Customizable upon request.
• Barbed Wire/Razor Wire: 20-40 g/m², primarily used for guardrails and the tops of isolation nets.
• Armored Cable: 30-70 g/m², used as the steel wire armor layer of cables.
• Mattress Spring: 15-30 g/m², used for mattress springs.
• Rope: 30-100+ g/m², primarily used for ship cables, slings, etc.

Two Types of Galvanizing

Electrogalvanizing

The process utilizes an electrolytic process to deposit a zinc layer. The zinc content ranges from 10 to 150 g/m², resulting in a smooth, uniform, and shiny appearance.

Hot-dip galvanizing

Immersed in molten zinc, a zinc-iron alloy layer is applied to the surface. The zinc content ranges from 60 to 275 g/m², resulting in a relatively rough, grayish appearance.

Key Differences

Hot-dip galvanizing typically provides a much thicker zinc layer than electrogalvanizing, resulting in stronger corrosion resistance. However, the surface is relatively rough, making it generally suitable for large items such as steel sheets, coils, and strips. Electrogalvanizing is more suitable for galvanizing smaller items such as wire, bolts, screws, and wire mesh.

Purchase Notes

(1) Zinc Grade: Choose between standard and thickened zinc coatings depending on the severity of the corrosive environment.

(2) Material: Typically low-carbon steel, but medium-carbon steel can be selected for higher strength.

(3) Surface Treatment: In addition to glossy finishes, PVC-coated galvanized steel wire is also available for added protection and color.

Common Packaging Forms

Coils

The most basic and common packaging method. They are in a circular bundle, without a reel. Weights range from 5kg to 1 ton.

Spools / Reels

Wire is wound onto a cylindrical wooden or plastic reel. They are convenient to use, but cost slightly more than coils.

Bundles/Pancake Coils

Short lengths of wire are rolled into a small, flat “pancake” shape and then secured with a cable tie or string. They are compact and lightweight, typically weighing 1kg, 5kg, or 10kg.
