4mm Galvanised Wire
4mm galvanised wire is a relatively thick, silvery-white carbon steel wire. Its silver color comes from the galvanized coating. The base material is Q195/Q235 carbon steel, offering good strength, corrosion resistance, and flexibility. It corresponds to AWG 6 gauge and SWG 8 gauge wire gauges and is a commonly used material in construction, agriculture, and wire mesh manufacturing.
Wanzhi Steel is a professional 4mm galvanized wire manufacturer in China. Our galvanized wire features a strong zinc coating, high tensile strength, and long service life. Our products are ISO certified, and we offer factory prices. Customized zinc coating and packaging are available.

What are Its Advantages?
- Corrosion Resistance: Whether hot-dip galvanized or electro-galvanized, galvanized wire ensures a long service life outdoors, up to 15 years or more. The thicker the zinc layer, the stronger the rust resistance.
- High Tensile Strength: Not easily broken, with good load-bearing capacity, and maintains stability after bending. Ideal for applications such as rebar tying, support, and suspension fixing.
- Good Processing Performance: Moderate hardness and good flexibility. Can be freely woven and twisted, suitable for processing slope protection netting and gabion baskets.
- Flexible Specifications: Coarse galvanized wire is generally available in rolls of 5kg-800kg. We provide packaging options such as woven bags, hemp rope, and plastic film, and can also be packaged at 1 ton per wooden pallet. Please feel free to contact us with your requirements.

- Everyday Uses: Used as the core wire in barbed wire and razor blade wire, woven into highway guardrails, animal and poultry isolation netting, clothing hanger substrate, and craft frames.
What is Its Production Process?
4mm hot-dip galvanized wire uses high-quality low-carbon steel (Q195/Q235) as the base material. It undergoes pickling and phosphating to remove oxide scale, followed by multiple cold drawing processes. Finally, it is hot-dip galvanized in molten zinc at 450℃ or electrolytically zinc-coated in an electrolyte solution.
Wanzhi Steel’s advanced processes ensure small wire diameter tolerances and uniform zinc layer adhesion, ultimately producing finished products with both high strength and excellent corrosion resistance.
