Introducing Putai New Perforated Corner Bead Wall L Angle Roll Forming Machine

This corner bead machine is engineered to produce the essential metal angles used to reinforce and finish the corners of drywall partitions and suspended ceilings, with the added value of pre-punched holes or slots. The perforations serve key functions: they allow for better mechanical keying of joint compound or plaster, provide channels for ventilation or wiring in certain applications, and can reduce material weight. The integrated design performs roll forming and perforation in a synchronized sequence, eliminating the need for secondary processing and ensuring perfect alignment of holes along the profile's leg.

The operation begins with a metal coil being fed into the machine. The material first passes through a precision punching unit, where a hydraulic or mechanical press creates the desired hole pattern. It then immediately enters the multi-stage roll forming section, where a series of contoured rollers gradually bend the pre-punched strip into a precise 90-degree angle profile. Finally, a flying cutoff system cuts the continuous profile to the required length.

• Drywall/Plasterboard Systems:​ For reinforcing internal and external corners where perforations enhance plaster adhesion.
• Suspended Ceiling Grids:​ As perimeter trim or supporting angles, where holes may facilitate airflow or mounting.
• Ventilated Wall or Soffit Systems:​ Where the perforated angle acts as a structural support within a rainscreen or cladding assembly.
