Riverside and Port Clarence
The Riverside estates run heavy plant that needs access platforms, crane-rail supports and replacement structural steel. We fabricate to survey dimensions and install around live operations.
Steel Fabrication in Middlesbrough.
Middlesbrough knows fabrication better than most towns in Britain, and Teesside's process sites, riverside estates and engineering works keep a constant need for platforms, access steel and structural packages. We design in-house, fabricate at our four-bay South Yorkshire workshop to BS EN 1090 Execution Class 2 and install across the Tees with our own directly employed teams.

Accredited for design, fabrication and installation, with the paperwork to prove it.
- BS EN 1090 Execution Class 2, UKCA marked: the execution class your engineer's design legally has to be fabricated to.
- Coded welders, BS EN ISO 9606: every structural weld made by an approval-tested welder, traceable on the documentation.
- ISO 9001 quality management: a quality system audited end to end, not a badge on a footer.

- GBP 10m public and GBP 10m employers liability: published figures, because your procurement team needs them on file.
- Directly employed, CSCS-carded site teams: the people on your site are ours, not subcontracted, so one team owns the result.
