Discover more about us
Our Name
Our full legal name is Triangle Engineering Services Limited. Most clients, contractors and partners know us as TriangleUK, which is the name we use on our website at triangleuk.com and in day-to-day communication. Both names refer to the same company.
What We Do
TriangleUK fabricates and installs structural steelwork across a wide range of environments — house extensions and domestic work, commercial refurbishments, industrial sites, utilities infrastructure and high-security installations.
Our services cover:
● Steel fabrication, custom-designed and built to specification
● Steel erection, with full method statements and risk assessments for every project
● Staircases and platforms, designed, fabricated and installed to legal requirements
● Gates and railings, with a full design service and powder-coated finishes in any RAL colour
● Beams and lintels, cut to size, marked and certificated, galvanised or zinc-primed
● Reactive repairs and welding, with a mobile workshop for plant, farm and industrial machinery
● Cable support steelwork and utilities infrastructure, including substations, shafts and tunnelling
● Security palisade fencing, SR1 A1 rated, supplied and installed from certified manufacturers
● Design and drawings using Tekla 3D modelling software
Our Standards
TriangleUK is certified to BS EN 1090-3. Every project we complete comes with a conformity notice, which clients need for building control and insurance purposes.
We carry full commercial insurance. Our team holds confined space A, B and C certification (UKPN), harness and working-at-height training, plasma cutting, manual handling, pendant-controlled overhead crane operation, and material lift certification. We do not subcontract training — we maintain it ourselves on an ongoing basis.
Project values have run from £1,000 to £300,000. We complete contracts on time and within budget.

We are based at Yew Tree House, Bromley Green Road, Ashford, Kent, TN26 2EG.
