Galvanized Steel Wire(ASTM A641 / Q195‑GI / Q235‑GI)
Our company specializes in supplying a full range of metal materials including stainless steel, galvanized steel, aluminum and copper products. Stainless steel delivers outstanding corrosion resistance via its chromium‑rich passive film. Galvanized steel features sacrificial zinc‑coating protection against rust for outdoor applications. Aluminum offers lightweight, good formability and natural oxidation resistance. Copper provides superior electrical conductivity and excellent thermal performance. All materials are available in various forms such as sheets, coils, wires and profiles to meet diverse industrial and construction demands.Scroll down to view detailed product information.

Product Description
Core Product Overview
Galvanized Steel Wire (ASTM A641 / Q195‑GI / Q235‑GI) is a hot‑dip zinc‑coated carbon steel wire, widely recognized as the preferred material for projects requiring reliable anti‑rust performance and cost‑effective tensile support. Compared with bare carbon steel wire, the continuous zinc‑alloy coating forms a physical and sacrificial protection barrier, greatly improving resistance to atmospheric corrosion, salt‑spray and humid surroundings, making it highly stable for outdoor and damp working conditions.
Our full stock range covers fine‑gauge wires (0.1mm‑3mm), medium‑gauge wires (3mm‑6mm), with surface options including normal zinc coating, heavy‑duty zinc coating and smooth uniform zinc finish. Every batch is sourced from top domestic and international steel mills, with 100% material test report (MTR) provided before delivery.

Unmatched Performance Advantages
Superior Anti‑Corrosion Sacrificial Protection
Continuous hot‑dip zinc coating creates both physical barrier and sacrificial anode protection. Galvanized steel wire resists atmospheric rust, humid environments and moderate salt‑spray erosion. Even minor surface scratches will still obtain cathodic protection, extending service life for outdoor tension‑loaded components.
Good Cost‑Efficiency & Processing Compatibility
Compared with stainless steel wire or anti‑rust painted carbon steel wire, galvanized steel wire delivers long‑term rust‑proof performance at favorable cost. It supports most cold‑working processes without extra anti‑corrosion painting steps, significantly cutting total project operation and maintenance expenses.
Reliable Surface Consistency & Weather Resistance
Uniform zinc‑coating layer provides stable anti‑rust capacity under variable outdoor weather. Controlled zinc‑coating weight keeps surface appearance consistent, suitable for both buried structural ties and visible exposed fencing components.
Outstanding Fabrication Versatility
It features good cold bending, twisting, weaving and machining performance. Straightening, cutting, twisting, braiding and spot welding can be completed smoothly. Proper process control avoids zinc‑layer peeling or cracking during fabrication.
