Warehouse & Distribution Centre Steelwork
The portal-frame steel behind warehouses and distribution centres. We design, fabricate and install clear-span steel frames, mezzanines and support steel to BS EN 1090 Execution Class 2.

















The steel that opens up the floor.
Warehouses and distribution centres live or die on clear, usable space and a fast programme. The steel frame delivers both: wide clear spans with no internal columns to work around, and a structure that goes up quickly and predictably. We design, fabricate and install the portal frames, eaves and edge steel, bracing and mezzanine floors that make up a warehouse structure, all to BS EN 1090 Execution Class 2 and erected by our own teams, so the steelwork stays on programme from the first column to the last purlin cleat.
Everything in a warehouse frame.
Portal frames, mezzanines, secondary steel and loading structures, fabricated and erected by our own teams.
Portal frames
Clear-span portal frames that open up the floor for racking, machinery and forklift routes without internal columns.
Mezzanine floors
Steel mezzanines for offices, pick towers and extra storage inside the building envelope.
Secondary steel
Purlins, side rails, eaves beams and bracing that carry the cladding and keep the frame stable.
Loading and canopy steel
Steel for loading bays, canopies and dock structures at the building perimeter.
Craneage and erection
Lift planning, sequencing and erection by our own teams, so the frame goes up safely and on programme.
Clear spans, fast erection, one accountable team.
A distribution shed is a race against the programme, so the steel has to arrive right and go up fast. We fabricate the portal frames and secondary steel to BS EN 1090 Execution Class 2, plan the erection sequence and craneage, and install with our own teams, coordinating with the cladding and groundworks trades so the frame is signed off on schedule.

Why warehouse steel is about the programme.
A distribution shed is a race against the schedule, so the steel has to arrive right and go up fast.

Questions clients ask us.
We design, fabricate and install the structural steel frame, secondary steel and any mezzanines. We coordinate with the cladding, roofing and groundworks trades on the programme, so the steel is right and on time for them to follow.
Yes. Clear-span portal frames are exactly what we fabricate for warehouses and distribution centres, so the floor stays open for racking, machinery and vehicle routes.
Yes. We fabricate and install steel mezzanine floors for offices, pick towers and extra storage within the warehouse envelope.
