Compressor Station Frames

Steel buildings that house compressors: portal frames with crane runway girders, purlins, girts, bracing and cladding, from the same PEB lines that build our industrial sheds.

Portal frames

Built-up columns and tapered rafters: plates matched on the beam line and welded by our Cloos robot, which takes the weld lines straight from the 3D model.

How is it possible at Allmarc?

Used here for: Portal frames

  • Plates matched and tack-welded
  • Automatic feed and stitch welding
  • H and I sections built from plate
All our machinery

Used here for: Portal frames

Tapered rafters and other non-uniform built-up sections, welded faster and with deeper penetration.

  • 40 m, state of the art
  • No programming: weld lines taken from the 3D model
  • Tandem torch: two wires at once
All our machinery

Crane runway

Runway girders and rails on column brackets, straightened and checked to crane tolerances.

Purlins and girts

Cold-formed sections roll-formed and punched in house.

05 / 08

Bracing

Rod and angle bracing in the end bays.

06 / 08

Cladding

Roof and wall sheeting; shown on one side so the frame stays visible.

07 / 08

Around your machine

The crane and the compressor are supplied by others. The building is sized round them.

A kit of parts

Frames, girders, purlins, bracing and cladding: every member numbered, match-marked and packed in erection sequence.

Why Allmarc

Experience you can trust.

We fabricate to your drawings and prove the fit in our own bay before anything ships. Open any line for the detail.
