Steel Portal Frame Buildings
Building Your Vision
with Expertise, Innovation, and Trust
We deliver complete value engineered steel portal frame packages, acting as Principal Contractor and working alongside a network of trusted, specialist partners to ensure every project is designed, fabricated and installed to the highest standard.

New Build Steel Portal Frames
Steel portal frame buildings are one of the most cost-effective construction solutions for commercial offices, industrial, defence, storage and agricultural buildings.
We take full responsibility for the management, coordination and safe delivery of your project – from initial concept and structural design through to on-site installation.
Our scope of single and multi-storey buildings extends to the full external cladding envelope, ensuring the building is delivered as a complete, weathertight structure – ready for us to take straight into fit-out without interruption to the programme or the need for additional contractors.
Portal frame buildings offer clear span internal spaces, significant flexibility of use, and the structural strength to support a wide range of applications, from warehousing, engineering and manufacturing facilities to agricultural buildings, bespoke commercial facilities and defence installations.
Where required, we can incorporate mezzanine floors, overhead gantry cranes and crane rails into the structure, maximising the operational potential of the building from day one.
We have considerable experience delivering within the defence sector, where the demands of security-sensitive, regulated environments require an additional level of rigour, reliability and discretion.
Steel Portal Frame Refurbisment
Refurbishing an existing steel portal frame building is often a cost-effective and sustainable alternative to a complete rebuild. Whether you’re extending the lifespan of an ageing industrial unit, upgrading its performance or adapting it to meet new operational requirements, a well-planned refurbishment can transform your facility while minimising disruption to your business.
Our steel portal frame refurbishment services include:
- Removal and replacement of roof and cladding
- Safe asbestos removal
- Roof refurbishment and repair
- Installation of roller shutter doors
- New doors and windows
- Structural steel repairs and strengthening
- Replacement of external building envelopes
- Internal fit-out and reconfiguration
- Mechanical and electrical upgrades
