Galvanized Wire

Product Overview

Galvanized Wire is a high-performance steel wire coated with a protective layer of zinc through the process of galvanization. This zinc coating provides exceptional corrosion resistance, making the wire ideal for outdoor applications, harsh environments, and long-term use. The wire combines the strength of high-quality low-carbon steel with the durability of zinc protection, offering excellent rust resistance, longevity, and reliability across various industries.

Available in both electro-galvanized (bright, smooth finish) and hot-dipped galvanized (heavy, durable coating) variants, this wire is the preferred choice for fencing, construction, agriculture, and industrial applications where exposure to moisture and weathering is a concern.

Characteristics

Excellent Corrosion Resistance

The zinc coating acts as a sacrificial barrier, protecting the underlying steel from rust and oxidation, even in humid or rainy environments.

Durable & Long-Lasting

Hot-dipped galvanized wire offers superior longevity, with a service life of 20–50 years depending on environmental conditions.

Strong & Reliable

Maintains high tensile strength while offering sufficient flexibility for bending, twisting, and tying.

Uniform Coating

Advanced galvanizing processes ensure a smooth, consistent zinc layer without flaking or peeling.

Versatile Finish Options

Choose between electro-galvanized for a clean, bright appearance or hot-dipped for maximum corrosion protection.

Customizable

Available in soft (annealed), semi-hard, or hard drawn temper to meet specific application needs.

Packaging

To ensure product integrity during storage and transportation, we offer multiple packaging options:

Packaging Type	Description
Small Coils	0.5 kg – 25 kg per coil; individually wrapped with PE film; packed in woven PP bags or cartons (typically 25 kg per bag).
Large Coils / Spools	50 kg – 800 kg per spool; wound on wooden, plastic, or steel reels; covered with moisture-proof paper and stretch film.
Cut Wire	Straightened and cut to specified lengths; bundled with plastic ties; packed in cartons or woven bags.
Palletization	Multiple coils or bags loaded onto wooden pallets, compressed with steel strapping, and fully stretch-wrapped for stability and moisture protection.
Custom Packaging	Labels, coil inner diameter (I.D.)/outer diameter (O.D.), and packaging materials can be customized per customer requirements.

Transportation

Loading Capacity:

• 20-foot container: 20–26 metric tons (depending on coil size and packaging format)

• 40-foot container: 24–28 metric tons

Shipping Modes: Sea freight, air freight, rail, and truck transport

Lead Time: 15–25 days after order confirmation (subject to quantity and specifications)

Storage Recommendations: Store in a dry, well-ventilated warehouse. Avoid direct exposure to rain, humidity, and corrosive chemicals. Keep coils on pallets to prevent contact with damp floors.

Handling: Use forklifts for palletized goods; ensure spools are properly secured to prevent rolling during transit.

FAQ

Q: What is the difference between electro-galvanized and hot-dipped galvanized wire?

A: Electro-galvanized wire has a thinner, brighter, and smoother zinc coating applied through an electrical process. It offers moderate corrosion resistance and is ideal for indoor or light-duty outdoor applications.

Hot-dipped galvanized wire is immersed in molten zinc, creating a thicker, heavier, and more durable coating. It provides superior corrosion protection and is recommended for harsh outdoor environments, agricultural fencing, and long-term applications.

Q: How long does galvanized wire last outdoors?

A: The lifespan depends on the galvanization type and environmental conditions. Hot-dipped galvanized wire with a heavy coating can last 20–50 years or more. Electro-galvanized wire typically lasts 5–15 years in outdoor settings. In coastal or highly industrial areas with high corrosion exposure, lifespan may be reduced.

Q: Does the zinc coating flake or peel?

A: High-quality galvanized wire features a well-bonded zinc layer that does not flake or peel under normal use, bending, or twisting. However, excessive bending or improper handling may cause cracking in very heavy hot-dipped coatings.

Q: Can galvanized wire be welded?

A: Yes, galvanized wire can be welded, but care must be taken. Welding burns off the zinc coating at the weld point, which may reduce corrosion resistance in that area. Proper ventilation is required as zinc fumes can be hazardous when heated.

Q: What is passivation?

A: Passivation is an additional treatment applied to electro-galvanized wire to prevent "white rust" (zinc oxidation) during storage and transportation. It extends the shelf life and maintains the bright appearance of the wire.

Q: Can you provide custom tensile strengths?

A: Yes. We offer galvanized wire in soft (annealed), semi-hard, and hard drawn tempers. Soft wire is flexible and easy to tie, while hard drawn wire offers higher tensile strength for applications requiring structural support.

Q: Is galvanized wire safe for use in drinking water applications?

A: Standard galvanized wire is not typically certified for potable water applications. For such uses, we recommend stainless steel wire or specially coated products that meet drinking water safety standards.

Q: Do you offer samples?

A: Yes, free samples are available for testing and quality verification. Shipping costs may apply. Please contact our sales team to arrange sample delivery.
