Billet

Billet is key semi-finished steel product with a small, uniform cross-section—typically square (100–200 mm side length) or round (100–200 mm diameter)—and a length of 3–12 meters. Unlike slabs (flat, for flat steel) or blooms (larger cross-sections, for structural sections), billets are specifically designed as feedstock for rolling into long steel products (e.g., bars, wire rods, seamless tubes) or for forging into precision mechanical parts. Its compact, regular cross-section enables efficient deformation into narrow, elongated finished goods critical for construction, automotive, and machinery industries.
