Capability
What we
deliver.
From equipment-led design and Eurocode connection sizing through hot-dip galvanising and CE / UKCA marking — every galvanised substation support structure is engineered around installed HV equipment, fabricated under BS EN 1090 EXC 3 and shipped erection-ready.
Phase 01
Equipment-led design
Steelwork engineered around the specified switchgear, isolators, CTs, VTs and busbars — co-ordinated with civils and earthing layouts before fabrication commences.
- Switchgear-co-ordinated
- Isolator & CT/VT supports
- Earthing-aligned
- Pre-fabrication checked
Phase 02
Hot-dip galvanised
Every support structure is hot-dip galvanised to BS EN ISO 1461 — decades of low-maintenance service life in exposed compound conditions.
- BS EN ISO 1461
- Vent & drain holes detailed
- Touch-up kits supplied
- Decades of service life
Phase 03
DNO and ICP aligned
Delivered to the technical specifications of UK DNOs and Independent Connection Providers — drawings, certification and ITPs structured around adoption requirements.
- UK DNO specifications
- ICP-ready
- Adoption-aligned drawings
- ITPs structured for handover
Phase 04
CE / UKCA marked
Fabricated under BS EN 1090 EXC 3 with full CE / UKCA marking, Factory Production Control and welder coding to BS EN ISO 9606-1.
- BS EN 1090 EXC 3
- Factory Production Control
- Welder coding 9606-1
- UKCA assured
