Applications

Where It Works

  • Bending pipe, tube, and structural sections for architectural metalwork, handrails, frames, and industrial fabrication
  • Rolling IPE, HEA, HEB, and UPN profiles into curved structural members for construction and heavy fabrication
  • Custom profile bending where standard tooling is insufficient and job-specific dies are required

Features

Built In

  • Heavily dimensioned frame built from certified quality steel plate handles the high bending forces required for structural sections and thick-wall pipe without deflection
  • Hydraulic drive with custom tooling options handles a wide range of pipe, tube, flat bar, angle, and structural profile in one machine
  • Every PBH can be custom-configured with tooling for specific profile requirements, from standard rolls to bespoke solutions available through Carlson
