Hot Dipped Galvanized Wire

Hot-dip galvanized wire is a low-carbon steel wire with a thick zinc coating. It is produced through a high-temperature hot-dip galvanizing process, unlike electro-galvanizing, resulting in better zinc adhesion and corrosion resistance. It is a raw material for barbed wire, fencing, crimped wire mesh, etc., and can also be used directly for construction binding or packaging, as well as as spring wire.

Wanzhi Steel offers hot-dip galvanized wire with zinc coatings ranging from Z30 to Z275. As a professional hot-dip galvanized wire manufacturer in China, our wire features a uniform zinc coating, long product lifespan, and stable performance over the long term.

Where are HDP GI wires used?

1. Galvanized steel wires are widely used as tie wire or binding wire for packaging or supporting wire. The most common binding wire for construction uses is gauge 22 & gauge 21 wire. It features good flexibility and affordable cost.
2. Making ropes, springs, nets, electrodes, nails, transmission cables, handicrafts;
3. Manufacturing wire mesh, fencing, wire mesh screen, highway guardrail, netting, etc.

Features of HDP GI Iron Wire

• Excellent corrosion resistance: Its surface has a thicker zinc layer than electro-galvanized wire, which bonds firmly with the carbon steel wire, forming physical protection and extending the wire’s lifespan.
• High strength and good toughness: The low-carbon steel base ensures high tensile strength and ductility, allowing it to withstand twisting and pulling without breaking during binding and bundling operations.
• Long service life: The hot-dip galvanized layer provides high-temperature stability, good resistance to ultraviolet rays, and a smooth, wear-resistant surface, making it resistant to aging and with a lifespan of up to 30 years.
• Easy processing: It can be woven into grassland netting, crimped wire mesh, chain link fences, gabion baskets, etc., and can also be easily processed into single-loop/double-loop baling wire, or welded into mesh panels.
• Beautiful and inexpensive: Its silvery-white appearance offers a certain degree of decoration compared to black annealed wire, while its price is much lower than stainless steel wire, making it an excellent value choice.

What Is Hot Dipped Galvanized Wire?

Hot-dip galvanized steel wire is made of low-carbon steel. Then it is immersed in a high-temperature zinc solution. The zinc layer thickness is 40-300 μm. But its surface is not uniform enough and dark in color. However the thick zinc layer provides excellent corrosion resistance. That’s why it can last for decades in the outdoor environment. Therefore, hot-dip galvanized products are widely used in the chemical industry, marine or shipbuilding industry, etc.

Hot Dipped Galvanizing Wire Process

Hot-dipped galvanized wire uses high-quality low carbon steel wire as raw material. The production process is as follows:

Steel rod coil – Wire drawing – Annealing – Rust removing – Pickling – Galvanizing – Coiling.

Hot Dipped Galvanized VS Electro Galvanized Wire

At Wanzhi Steel, we offer both steel wire with electro-galvanized and hot-dip galvanized coatings.

1. Zinc layer thickness: The maximum zinc content can reach up to 275 g/m² for the hot-dipped one, while that of the cold galvanized one is only 3-20 g/m².

2. Corrosion resistance. The hot dip galvanizing wire has better corrosion resistance than the electro-galvanized one. Generally, its service life is more than 10 years even in outdoor environments. However, electro-galvanizing is a physical process in which a layer of zinc is applied to the surface of the wire by electroplating. The thickness of the finished coating is smooth and shiny, but thin. Generally, it can only last a few months. So it is not as durable as the hot-dip galvanized one.

3. Difference in appearance. Hot-dip galvanizing wire has a dull and unpleasant finish. While electro galvanized wire has a smooth surface and a bright appearance.

4. Price difference. Hot dip galvanizing is more expensive when compared to electro-galvanizing. But the zinc coating of the former is thicker, and the longer the service life. So in the long term, the former one is more cost-effective.

5. Different applications. Because hot-dip GI Wire offers superior corrosion resistance, it can be used for any application, including harsh or humid environments. For example, it is an ideal choice for oil processing, marine exploration, shipbuilding, gas transmission, scaffolding, bridges, road guardrails, and other agricultural and construction uses.                                

Hot-dip Galvanized Wire Price

The price of hot-dip galvanized wire is shown in the table below. Prices are affected by wire diameter, zinc coating thickness, packaging, and order quantity. The thicker the zinc coating, the higher the price. Standard wire diameters are cheaper than custom diameters.

Diameter (mm)	Gauge	USD/ton
2.0	~12-14 Gauge	680−680−720
2.3	~10-12 Gauge	600−600−700
2.5	~10 Gauge	490−490−550
‌3.0‌	‌~8-9 Gauge‌	‌490−490−675‌
3.2	~8 Gauge	500−500−580
