Services
Delivered and installed by the people who made it
Every product is tested and trial-erected in-house before it leaves us. Our own team then delivers and installs it on site, anywhere in the UK.

What’s included
What we make
A starting point rather than a limit — most of what we build is one-off, so if it is not listed it is still worth asking.
Why it works
Three things that keep a job on track
Drawn before it is cut
2D or 3D AutoCAD drawings produced in-house and agreed with you, so the design is settled before any steel is bought.
Trial-erected before it ships
Assemblies are tested and trial-erected at our own works, so site time is fitting rather than fixing.
Installed by our own team
The people who deliver and install it work for us, and hold CSCS accreditation for site work.

How we work
From idea to finished install, all in-house
Design & CAD
25+ years using in-house CAD — 2D or 3D drawings produced electronically in AutoCAD and refined with you as the design develops.
Fabrication
Built in-house by our dedicated team, to your specification and in accordance with the latest regulations and British Standards.
Testing
All products are tested and trial-erected in-house as required, before they’re ever installed on site.
Delivery & Install
Our own team delivers and installs the finished steelwork, anywhere in the UK.
UK coverage
Delivery & Install, delivered the length of the country
A lot of what goes wrong on a steel install comes from a handover: one firm fabricates, another fits, and the gap between them becomes the client's problem. We do not have that gap.
Everything is drawn, cut, welded and trial-erected at one works, then delivered and installed by our own team. A job four hours away gets the same fabricator and the same fitters as one four miles away — the distance changes the planning, not the standard.
Accredited
Checked, carded and marked
The paperwork a main contractor asks for before anyone sets foot on site.
CE and UKCA marking, CHAS accreditation and CSCS cards for every employee and sub-contractor on site.

Yes. All products are tested and trial-erected in-house as required, before they are ever installed on site.
Can you deliver without installing?
Yes, if that suits the job. Call Craig on 01782 561526 to talk through what you need.

Send us the drawing, or just the problem
If you have a drawing we will price from it. If you have a space, a load and a deadline, we will work the design up with you from there.
