Plant & Equipment Support Steelwork
Support frames, plant decks, plinths and gantries for the equipment that runs your site. We detail, fabricate and install plant support steelwork to BS EN 1090 Execution Class 2.

















Built around the equipment that runs your site.
Industrial sites are full of equipment that has to be held up, walked around and maintained: tanks, machinery, HVAC plant, pipework and process kit. We fabricate and install the support steel that carries it, from plant decks and access platforms to machine bases, plinths, support frames and pipe gantries. Everything is made in our own workshop to BS EN 1090 Execution Class 2 and installed by our own teams, so the steelwork that keeps your plant running is detailed, fabricated and fitted by one firm.
The steel that carries and surrounds your plant.
Plant decks, machine bases, support frames and gantries, fabricated to fit your site and installed by our own teams.
Plant decks and platforms
Raised steel decks and platforms that carry plant and give safe access around it.
Machine bases and plinths
Steel bases, frames and plinths that mount and support machinery and process equipment.
Support frames
Bespoke support frames for tanks, vessels, ductwork and services.
Pipe and services gantries
Gantries and support steel that carry pipework and services across a site at height.
Access and edge protection
Stairs, handrails and edge protection fabricated with the support steel, so the platform is safe to use.
The steel that holds your plant up and lets your team work around it.
Plant support steel has to carry the load, meet access and safety needs, and fit around equipment that is often already there. We survey, detail, fabricate to BS EN 1090 Execution Class 2 and install with our own teams, so support frames, decks and gantries go in accurately and safely around live plant.

Why plant steel is a survey-first job.
It has to fit around equipment that is often already there, so we measure before we make.
