Jinbolida Angle Iron Roll Forming Machine – Fast, Low-Waste Production of Equal and Unequal Angles

The Jinbolida Angle Iron Roll Forming Machine forms straight, dimensionally accurate equal-leg and unequal-leg angles directly from steel coil. Rather than rolling flat bar and then bending it, the levelled strip is formed straight into an angle in a short, efficient roll set, typically only 6–8 passes for a 90° angle, with almost no scrap. Changing a few roll sets and adjusting stand spacing switches the machine to a different leg width or thickness, and in-line punching and cutting options produce finished, ready-to-bolt components. It's a cost-effective way to make standard angles in volume for construction, racking and general fabrication.

How It Forms Angles

• Levelled strip enters the forming roll set
• The first pass uses vertical edge rolls to pre-press bend guide lines on both edges of the strip
• Following horizontal passes gradually bend both legs upward
• Central horizontal rolls support the middle of the strip to prevent wrinkling
• A 90° angle is typically formed in 6–8 passes
• For unequal angles, forming on each side is adjusted separately

Key Features

• Forms equal-leg and unequal-leg angles directly from coil
• Short, efficient roll set (typically 6–8 passes for a 90° angle)
• Near-zero scrap from forming, for excellent material utilisation
• Quick size changes by swapping a few roll sets and adjusting stand spacing
• High-speed, continuous production
• Stable machine design, with cooling to control roll temperature during continuous high-speed running

Configurable Options (to be confirmed with Jinbolida)

• In-line punching for bolt holes
• Combined cut-and-punch die that cuts to length and punches end holes in one action
• Flying saw or die cutting for square end faces
• End-of-line straightener for angles with strict straightness requirements

Applications

• Construction and structural steel angles
• Shelving, storage racks and racking systems
• Solar mounting bracing and end-clamp angles
• Support brackets and frames
• General metal fabrication

Frequently Asked Questions

• Can it make unequal angles? Yes. Forming on each side is adjusted to produce unequal-leg angles.
• How are sizes changed? Change a few sets of forming rolls and adjust the stand spacing.
• How much scrap does it produce? Very little. Forming angles directly from strip gives near-complete material utilisation.
• Can angles be punched and cut on the line? In-line punching and cutting units can be integrated. Ask Jinbolida about the options.
• What should I send for a quotation? Angle sizes (leg widths and thickness), equal or unequal legs, material grade, required lengths, hole patterns, output, and your local voltage and frequency.
