Round Corner Square (RCS) bars are solid metal bars with a square cross-section and rounded edges, combining the strength of square bars with improved handling and processing characteristics. These bars are produced through precise rolling processes, ensuring uniform dimensions and high-quality surface finishes.
- Rolled Bars Size: (Round mm) — 24mm to 150mm
- Round Corner Square (RCS) (mm) — 45,50,52,54,55,63,70,75,85,90,100
RCS bars are widely used across forging, machining, and structural applications. The rounded corners reduce stress concentrations and improve flow during forging, making them suitable for producing high-integrity components in automotive, engineering, and heavy machinery sectors.
Manufactured from various grades of steel and alloy materials, Round Corner Square bars offer excellent mechanical strength, dimensional accuracy, and workability. Their robust construction and reliable performance make them ideal for parts requiring both formability and load-bearing capacity.
Whether used as raw material for closed-die forgings, in construction frameworks, or for manufacturing critical machine components, RCS bars provide a versatile solution that meets demanding industry standards.
