Overview

A premium take on Structural Steel Fabrication

Structural steel is where fit-up discipline shows. G&A Precision Systems fabricates equipment frames, pipe supports, access platforms, stair stringers, plate assemblies, and custom weldments from your structural drawings or 3D models. We work in wide-flange, tube, channel, angle, and heavy plate, and we hold the tolerances the erection crew needs so bolts go through the holes on site. When the job calls for it, we bring the same crew to the field for structural welding and repairs.

This service is built for industrial teams that need fabrication to match the drawings, material specifications, and project schedule. We manage joint preparation, fit-up, welding, traceability, and final inspection so the work arrives ready for installation.

What's Included

  • Pipe racks, supports, and hangers
  • Platforms, stairs, ladders, and handrail
