Hot dip galvanized steel wire, also known as GI wire, is a strong, durable steel wire coated with a layer of zinc for dependable rust and corrosion protection. Offered in 3.6mm and 4.6mm diameters with tensile strength up to 1200MPa, this galvanized steel wire suits fence panels, nets, construction, and farm work. ZZ Group supplies it directly, with packing arranged around each order.
Galvanized steel iron wire starts with a solid steel core, and the galvanizing process wraps that core in a layer of zinc. That coating is what keeps rust and corrosion at bay, because it stops the steel from coming into direct contact with moisture, chemicals, and other external elements that cause deterioration. This hot dip galvanized steel wire is available in 3.6mm and 4.6mm diameters, in grades like Q195/Q235b, 45#, 55# and 60#, with zinc coating from 15g/m2 up to 600g/m2 and a tensile strength range of 290MPa to 1200MPa.
The galvanized steel wire 3.6mm size tends to be the go-to for work that demands real strength. That thicker cross-section delivers superior load-bearing capacity, so it copes with heavy-duty tasks such as reinforcing concrete, holding up fences, and supporting crops season after season. Because the zinc layer extends the working life of the wire, replacement costs stay low over the years, which makes it a cost-effective option for long-running projects. Whether the work is construction, fencing, or agriculture, this gi steel wire keeps performing in the field, and ZZ Group can deliver it as a finished product with packing done to suit the customer's request.

● Stands up to harsh environmental conditions, from rain and snow to extreme temperatures, without losing strength or corroding.
● The galvanized coating gives it excellent chemical resistance, so corrosive substances in industrial settings leave it unaffected.
● The 3.6mm diameter provides superior strength and load-bearing capacity for heavy-duty work.
● A steel wire galvanized this way lasts longer, which trims replacement and repair costs over the years.
● Reliable performance and minimal upkeep keep downtime low on the job.
What sets this galvanized steel wire apart:
● The galvanized layer acts as a protective barrier, keeping the steel from direct contact with external elements that trigger rust and deterioration.
● With the coating in place, the wire lasts far longer, which makes it a cost-effective option for long-lasting applications.
● The 3.6mm diameter wire brings superior strength and load-bearing capacity, so it fits a variety of heavy-duty tasks.
● Harsh weather is not a problem. Rain, snow, or extreme temperatures, the wire holds its integrity and strength without corroding.
● The galvanized coating offers excellent chemical resistance, so corrosive substances common in industrial environments leave it unaffected.
● Reliable performance means fewer surprises on site and less need for frequent replacement or repairs.
● Fence panels and nets – high tensile strength plus corrosion resistance keep panels rigid and boundaries clearly defined, season after season.
● Construction reinforcement – reinforcing concrete structures boosts durability and strength on site.
● Farm support systems – trellising plants, supporting crops, and setting up livestock feeding areas.
● Heavy-duty jobs – the galvanized steel wire 3.6mm carries real load, and the coating shrugs off corrosive substances.
● Outdoor exposure – rain, snow, and extreme temperatures will not corrode the wire or weaken it.
Q: Are galvanized steel wire and gi steel wire the same thing?
A: Yes. Galvanized steel iron wire and gi steel wire both refer to the same product: steel wire galvanized with a layer of zinc for rust and corrosion protection.
Q: What diameters are available?
A: 3.6mm and 4.6mm are standard, and all sizes are available on request.
Q: What zinc coating weights can I get?
A: Zinc coating runs from 15g/m2 to 600g/m2.
Q: What grades and tensile strength are on offer?
A: Grades include Q195/Q235b, 45#, 55#, 60# and more, with a tensile strength range of 290MPa to 1200MPa.
Q: How is the wire packed?
A: Packing follows the customer's request, commonly 5kgs/roll, 25kgs/roll, or 50kgs/roll, with pp film inside and hessian cloth outside or pp woven bag outside.
