High-Strength Carbon Steel Wire Rods: Hot-Rolled Precision for Construction & Industrial Use.
Multi-Grade Carbon Steel Wire Rods with Custom Coatings.
Engineered to JIS G3466, EN 10219, and ASTM A53 standards, our carbon steel wire rods offer 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 fabrication costs by 15–20% through precise dimensional control and anti-corrosion coatings.
Key Features:
- Grades: Q195, Q235, Q345, ASTM A53 GrA/GrB, STKM11, ST37, 16Mn
- Surface Options: Hot-dip galvanized (270g/m²), PVC-coated (0.4–1.2mm), or anti-rust oil
- Certifications: ISO 9001, RoHS, Mill Test Reports
