Hot-Dip Galvanized Steel Wire Rods: High-Strength Corrosion Resistance for Construction & Infrastructure.
Multi-Grade Carbon Steel Wire Rods with Zinc Coating (40–120 g/m²).
Engineered to ASTM A53, JIS G3466, and EN 10219 standards, our galvanized wire rods deliver 330–550 MPa tensile strength for scaffolding, fencing, and hydraulic systems. Available in 0.1–12mm wall thickness (±5% tolerance) and 5–14m coil lengths, these rods reduce rust-related maintenance costs by 30–50% through hot-dip galvanizing (HDG) or PVC coating.
Key Features:
- Grades: Q195, Q235, Q345, ASTM A53 GrA/GrB, ST37, ST52
- Zinc Coating: 40–120 g/m² (Class B to Class C per ISO 1461)
- Certifications: ISO 9001, Mill Test Reports, RoHS
