Corner Bead Punching and Roll Forming Machine | PUTAI, Tianjin, China

PUTAI Perforated Corner Bead Roll Forming Machine – Punching and Forming in a Single Pass

The PUTAI perforated corner bead roll forming machine punches and forms metal corner beads in one continuous pass. Synchronised hole punching is built into the line, so uniformly spaced perforations are created as the strip is formed, with no separate punching step. The machine forms 0.5 mm galvanized steel through 10 stations, controlled by a PLC, and cuts each bead to length with a servo tracking cutter. Beyond corner beads, the same line can produce perforated wall angles for ceiling perimeters, giving manufacturers two products from one compact machine.

Why Single-Pass Punching Matters

• No separate punching machine or extra handling between steps
• Holes stay perfectly aligned with the formed profile along the full length
• Uniform perforation spacing for consistent plaster grip
• Faster production and lower labour cost per metre

What the Machine Produces

• Perforated corner beads: Reinforce and protect drywall and plaster corners, with holes that let plaster or joint compound lock the bead in place
• Perforated wall angles: Used as perimeter trim and support angles in suspended ceiling grids

Key Features

• Integrated, synchronised hole punching and roll forming
• 10 forming stations with Cr12 rollers for accurate, straight profiles
• PLC control for simple setting of length and quantity
• Servo tracking cutting system with position feedback for precise lengths and minimal waste
• Straightening unit applies gradual, even force to keep beads true without cracking
• Energy-efficient 5.5 kW main motor with gear drive
• Fully automatic operation

How the Production Line Works

• Feeding: Galvanized strip is fed from the coil into the line
• Punching: Perforations are punched in sync with the line speed
• Roll forming: 10 stations shape the strip into the corner bead or angle profile
• Straightening: The profile is straightened with gentle, even pressure
• Servo cutting: Each piece is measured and cut to the programmed length

Applications

• External and internal corners on drywall and plasterboard
• Plastered walls in residential and commercial buildings
• Perimeter trim for suspended ceiling grids
• Renovation and fit-out projects

Frequently Asked Questions

• Where is this machine made? At PUTAI's factory in Bazhou, Hebei, China. The company office is in Tianjin, and machines are exported worldwide.
• Does the machine punch the holes itself? Yes. Punching is built into the line and synchronised with forming, so beads are perforated and formed in one pass.
• Can it make wall angles as well as corner beads? Yes. It can produce perforated wall angles for ceiling perimeters as well as corner beads.
• What thickness does it form? 0.5 mm galvanized steel.
• How is the machine controlled? Through a PLC, where operators set length and quantity.
• How long is delivery? Around 80 days.
• What should I send for a quotation? Your profile drawing or sample, hole size and spacing, thickness, target output, and local voltage and frequency.
