Carbon Steel Wire Rod — Factory Direct Supplier | Huaxia-Steel
Huaxia-Steel supplies carbon steel wire rod in grades SAE1006, SAE1008, SAE1010, SAE1015, SAE1018, SAE1022, and SWRM series for wire drawing, fastener manufacturing, welding electrode cores, and construction binding wire applications. Our wire rod is produced by continuous casting and hot rolling at ISO-certified partner mills, with strict control over chemical segregation, surface quality, and coil uniformity.
Product Overview
Carbon steel wire rod is the primary semi-finished product for drawn wire, nails, screws, mesh, and reinforcing applications. Diameter typically ranges from 5.5mm to 16mm, supplied in coiled form (1,500 – 2,200kg per coil). Hot-rolled wire rod requires subsequent processing (pickling, coating, drawing) before final use, making surface cleanliness and internal soundness critical quality factors.
