Perforated Angle Bead Roll Forming Machine | PUTAI, Tianjin, China

PUTAI Perforated Angle Bead Roll Forming Machine – Corner Bead Production Line for Drywall and Plaster

The PUTAI perforated angle bead roll forming machine is an automatic production line for manufacturing metal corner beads that protect and reinforce the external corners of drywall, plaster and masonry walls. It forms 0.3–0.5 mm galvanized or pre-painted steel through 15 stations into straight, rigid L-shaped or bullnose corner profiles, then cuts each bead to length on the move with a servo tracking cutter. Running at up to 30 m/min, it gives building material manufacturers a steady supply of consistent, high-quality corner beads.

What Is a Perforated Angle Bead?

• A metal corner profile fixed to external wall corners before plastering or drywall finishing
• Perforations along the wings let plaster or joint compound bond through for a strong, secure fix
• Protects corners from knocks and damage over the life of the building
• Creates a straight, sharp or rounded corner line for a professional finish
• Available as a square L profile or a rounded bullnose profile
