Aluminium substation steel

Aluminium substation support structures, lightweight and corrosion-resistant.

Our aluminium substation support structures provide a lightweight, corrosion-resistant solution for modern electrical infrastructure projects — ideal for demanding substation environments where weight and maintenance are critical.

Capability

What we
deliver.

From lightweight aluminium frame design and BS EN 1090-3 EXC 3 fabrication through coded aluminium welding and bimetallic detailing — every aluminium support structure is engineered for marine, coastal and weight-critical substation environments.

  • Lightweight performance

    Phase 01

    Lightweight performance

    Significantly lighter than galvanised steel — reducing crane, foundation and installation loadings, and accelerating site handling on remote substation sites.

    • Reduced crane loads
    • Lower foundation requirements
    • Faster handling
    • Easier installation
  • Naturally corrosion-resistant

    Phase 02

    Naturally corrosion-resistant

    Aluminium needs no protective coating system — ideal for coastal, marine and chemically exposed environments where coating maintenance becomes a recurring cost.

    • No coating required
    • Coastal / marine ready
    • Chemical resistance
    • Long maintenance-free service
  • BS EN 1090-3 EXC 3

    Phase 03

    BS EN 1090-3 EXC 3

    Fabricated under BS EN 1090-3 Execution Class 3 for aluminium structures, with coded aluminium welders and full mill traceability per profile.

    • BS EN 1090-3 EXC 3
    • Coded aluminium welders
    • Mill traceability
    • CE / UKCA marked
  • Mixed-material packages

    Phase 04

    Mixed-material packages

    Aluminium supports are delivered alongside galvanised steel frames under one workflow — bimetallic connections, electrical fixings and earthing all engineered in.

    • Bimetallic connections
    • Earthing engineered in
    • Single project manager
    • Co-ordinated delivery
  • ISOQAR ISO 9001 certified
  • Auva ISO accredited
  • UKCA marking
  • Constructionline Silver member
  • Betterweld accredited
  • SAP Ariba supplier

Aluminium substation steel

Aluminium substation support structures

Lightweight aluminium structural steel support structures for the UK power sector — fabricated to BS EN 1090-3 EXC 3 with coded aluminium welders, ideal for coastal, marine and weight-critical substation environments.

Bimetallic connections, equipment fixings and earthing arrangements are engineered into the design so the structure integrates with the wider galvanised steel compound.

Where aluminium wins

Reduced weight, no protective coating and exceptional corrosion resistance — engineered by our in-house team for sites where galvanised steel would carry a maintenance penalty.

One workflow, mixed materials

Aluminium and galvanised steel supports are delivered under one project workflow, one project manager and one delivery sequence.

FAQs

Aluminium substation
support structures.

Lightweight aluminium substation support structures fabricated for utilities, contractors and energy providers across the UK.

  • Aluminium is significantly lighter, naturally corrosion-resistant and requires no protective coating — ideal where weight, marine exposure or coastal environments would otherwise drive higher maintenance costs.
