Wire rod is a long steel semi-finished product manufactured by hot rolling billets on continuous rolling mills. It has a round cross-section and is wound up in coils.
Unlike other steel products, wire rod exhibits a significant commodity range variety; based on its chemical composition the following families of products and their differing corresponding uses can be identified:
- mild steel rod, used to manufacture welded mesh and drawn rods (black, annealed and coated)
- wire rod with medium or high carbon content
- welding rod
- special steel rods used in hot and cold die-pressing, drawing and extrusion.
