Steel Bars Rolling Mill | High-Precision Bar Production Line

Advanced Steel Bars Rolling Solutions

KWM Machinery’s Steel Bars Rolling Mill delivers ±0.2mm diameter tolerance for Φ10mm-Φ150mm round bars, square bars, and hex bars, achieving 200-800 TPH output compliant with ASTM A36, EN 10025, and JIS G3101 standards. Our systems integrate thermo-mechanical rolling (TMR) technology, reducing energy consumption by 25% while enhancing tensile strength by 15% compared to conventional mills.

Key Features
