Galvanized Steel Wire(ASTM A641 / Q195‑GI / Q235‑GI)

 

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.
