Product Name: Steel Bar (Round, Square, Flat & Rebar)
Introduction
Steel Bars are fundamental metal products supplied in various cross-sections - round, square, flat, and deformed (rebar) - serving as raw material for machining, forging, fabrication and construction. Available in mild/carbon, alloy and stainless grades, steel bars offer predictable mechanical properties, wide availability, and versatile finishing options to meet structural, mechanical and industrial needs.
Typical Types & Applications
Round Bars: Shafts, pins, axles, turnings and fastener blanks.
Square Bars: Keys, bearing blocks, machine parts and architectural elements.
Flat Bars: Brackets, flanges, gussets, tool blanks and fabrication stock.
Deformed Bars (Rebar): Reinforcement for concrete structures (building, bridges, civil works).
