Carbon Steel Wire Rod — Factory Direct Supplier | Huaxia-Steel
Carbon steel wire rod is the starting material for virtually every steel wire product — from galvanized fencing wire and welding electrodes to prestressed concrete strand and cold-headed fasteners. At Huaxia-Steel, we supply hot-rolled carbon steel wire rod directly from ISO 9001 certified mills in China, with full material traceability and competitive export pricing.
Our wire rod product range covers low-carbon grades for drawing and forming, medium-high carbon grades for mechanical spring and rope wire, and specialty grades for welding applications. All products are supplied in coil form with controlled cooling for consistent microstructure.

Typical Applications
- Wire drawing: Feedstock for drawing mills producing galvanized wire, fencing wire, barbed wire, and binding wire from 0.5 mm to 5.0 mm finished diameter
- Welding consumables: Feedstock for MIG/MAG welding wire (ER70S-6, ER70S-3), submerged arc welding wire, and welding electrodes (E6013, E7018 core wire)
- Fastener manufacturing: Cold heading quality (CHQ) wire rod for producing bolts, screws, rivets, and nuts through cold and warm forming
- Construction mesh: Feedstock for welded wire mesh, reinforcing mesh, and rebar cages used in concrete structures
- Spring manufacturing: Medium-high carbon grades for producing compression springs, tension springs, and torsion springs for automotive and industrial applications
- PC strand: High-carbon grades (0.75-0.85% C) for producing 7-wire prestressed concrete strand (ASTM A416 Grade 270)
Quality Assurance
Every shipment of carbon steel wire rod from Huaxia-Steel includes:
- Mill Test Certificate (MTC 3.1 per EN 10204) with full chemical composition, tensile strength, reduction of area, and grain size
- Dimensional inspection report for diameter, ovality, and surface quality per ASTM A510 or applicable standard
- Heat number traceability — each coil tagged with heat number matching the MTC
- Optional third-party inspection by SGS, Bureau Veritas, or TUV at mill or port before loading
- Optional additional testing: Decarburization depth, inclusion rating (ASTM E45), macro-etch, and Jominy hardenability
Packaging and Shipping
Standard export packaging for carbon steel wire rod coils:
- Each coil secured with minimum 4 steel strapping bands (circumferential and radial)
- Wrapped in VCI (Volatile Corrosion Inhibitor) paper for rust prevention during transit
- Outer polyethylene film wrapping (UV-stabilized for outdoor storage up to 3 months)
- Coils loaded on fumigated wooden pallets or directly into 20ft containers (typically 22-25 tons per container)
- Container desiccant: minimum 12 kg silica gel per 20ft container
- Leading ports of loading: Tianjin, Shanghai, Qingdao, Ningbo
