Heavy Structural Steelwork
High-tonnage, heavy-section steel for large commercial and industrial structures. We detail, fabricate and install heavy structural steelwork to BS EN 1090 Execution Class 2.
Big steel, handled as one operation.
Some structures need more than standard framing: big sections, plated members, high tonnage and the craneage to erect them. We fabricate heavy structural steelwork for large industrial and commercial projects, from heavy transfer steel and plated girders to large-section columns and long-span primary frames. It is all made in our own workshop to BS EN 1090 Execution Class 2 and installed by our own teams, with the lifting and sequencing planned so heavy steel goes up safely and on programme.
High-tonnage steel, fabricated and erected as one operation.
Heavy frames, plate girders and transfer steel, with the craneage and sequencing planned by the team that installs it.
Heavy primary frames
Large-section columns and beams for high-load and long-span structures, fabricated to your engineer's design.
Plated and built-up members
Welded plate girders and built-up sections where rolled steel will not carry the load or span.
Heavy transfer steel
The deep transfer members that carry loads across large openings and changes of grid.
Craneage and erection planning
Lift plans, sequencing and craneage worked out so heavy members are erected safely and in the right order.
Site installation
Erected and bolted up by our own directly employed teams, so the heavy steel stays with one firm on site.
Heavy steel is as much about handling as it is about fabrication.
Large sections and high tonnage need the right fabrication, the right lifting plan and the right people on site. We fabricate to BS EN 1090 Execution Class 2, plan the erection and craneage, and install with our own teams, so heavy structural steel is delivered as one controlled operation rather than handed between suppliers.

Why heavy steel needs one firm from workshop to site.
Big sections and high tonnage take the right fabrication and the right lift plan.

Our workshop fabricates large and plated members, not just light framing, so heavy steel is made in-house to one standard.
-
02
Coded welding, traceable
Heavy welds made by coded welders to BS EN ISO 9606, with procedures and records supplied.
-
03
BS EN 1090 Execution Class 2, UKCA marked
Fabricated to the execution class your engineer's design is specified against, with the declaration of performance.

04
Erection planned and delivered by our own teams
We plan the lift and the sequence and put our own people on site, so heavy steel is one controlled operation.
"I've worked with UIS for several years on some high profile and very complex projects. Their attitude and work ethic are second to none - providing high quality services and products which are delivered safely and on time every time. Overall they are a pleasure to do business with and wouldn't hesitate recommending UIS for any steelwork or metalwork packages."
Questions clients ask us.
Large sections, plated and built-up members and high tonnage: the primary steel for large industrial and commercial structures, as opposed to light or domestic framing.
Yes. We plan the lift, the sequence and the craneage as part of the package, so heavy members are erected safely and in the order the frame needs.
Yes. Where a rolled section will not do, we fabricate welded plate girders and built-up members to your engineer's design.
