Core Equipment

Processing equipment built for repeatable accuracy.

Equipment information should be reviewed periodically so capacities and current machine configurations remain accurate.

Voortman V808 robotic cutting machine

Voortman V808

Eight-axis robotic thermal cutting for complex profiles, copes, connections, and four-side marking.

Steel fabrication equipment

Voortman V630

Three independent drilling heads for simultaneous flange and web processing, tapping, countersinking, and layout marking.

Plate processing operations

GPF 1024 Plate Processor

10-foot by 24-foot table with oxy-fuel, plasma cutting, and multi-station drilling capability.

Steel cambering and fabrication

Cambco 825

412-ton cambering machine capable of processing wide-flange material for project-specific camber requirements.

Steel saw processing

Marvel 8 Mark II

Vertical-tilt framing saw with miter-cutting capability for structural members and complex angles.

Steel finishing operations

Angle Processing & Deburring

Dedicated angle and flat-bar processing plus automated edge deburring for cleaner downstream fabrication.

Production Approach

Automation where it matters. Experience everywhere else.

Automated processing improves repeatability, while experienced fitters, welders, inspectors, and project teams manage the conditions that require judgment.

  • Material identification and traceability
  • Controlled fit-up and welding procedures
  • In-process and final inspection
  • Sequenced shipping and documentation
