Pipe Racks & Access Platforms

The steel that carries every process line across a plant: multi-tier pipe racks, their bracing and the walkways that go with them, all fabricated, trial-assembled and shipped as bolt-up frames.

A pipe rack, as we build it

Bays, tiers and heights follow your plot plan; this model is one example. What we show is how the frames are cut, drilled, welded and match-marked for bolt-up.

02 / 07

Portal frames

H-section columns and tier beams, drilled and match-marked so each frame bolts up on site as a unit.

03 / 07

Tied together, braced once

Struts tie the frames along the run; one braced bay per line of columns takes the longitudinal load from thermal growth, surge and wind.

04 / 07

What it carries

Shoes under every line at every frame, so pipes slide on the steel instead of wearing through it.

05 / 07

Access built in

A grated walkway on cantilever brackets, a two-rail handrail and toe board, and a caged ladder, all fitted in the works.

06 / 07

Base plates

Base plates and anchor bolts at every column.

07 / 07

A kit of frames

Frames, struts, bracing, shoes and access, every piece numbered for the erection sequence.
