Product Overview
Galvanized Steel Wire is low-carbon steel wire treated with a zinc coating for corrosion protection. It is manufactured from Q195, Q235, SAE1006 and SAE1008 base steel and is available in diameters from 0.2mm to 6.0mm, covering a wide range of construction, agricultural, fencing and industrial requirements.
The product supports both Hot Dipped Galvanized (HDG) and Electro Galvanized (EG) processes. Different zinc coating classes are available, allowing buyers to select the appropriate corrosion protection level for indoor use, agricultural applications, outdoor fencing, coastal environments and more demanding chemical or seawater conditions.
For dimensional consistency, wire diameter tolerance is controlled at ±0.02mm for 0.2–1.0mm wire and ±0.05mm for 1.2–6.0mm wire. The product also matches British SWG wire gauges from 6# to 24#, providing flexibility for international purchasing specifications.
Galvanized Steel Wire can be supplied in coils, spools or pre-cut straight lengths. Coil weights range from 1 kg to 1000 kg, pre-cut wire can be produced from 10 cm to 6 m, and spool inner diameters range from 100mm to 600mm, making it suitable for both general fabrication and industrial-volume procurement.
