Portal Frame Steel Buildings - Design, Fabrication & Installation


MTST Structures Ltd designs, fabricates, and installs bespoke portal frame steel buildings across Southampton, Hampshire, and throughout the UK. Whether you need an industrial warehouse, agricultural building, or commercial unit, we deliver complete solutions tailored to your exact specifications.

Custom Portal Frame Buildings Built to Your Requirements:

Every building we supply includes full 3D modelling and GA drawings, with structural calculations specific to your postcode for national average wind and snow loadings. We provide foundation calculations and can arrange groundworks services to give you a complete turnkey solution.

Hot-Rolled Portal Frame Buildings:

Our hot-rolled portal frame structures are engineered for strength and durability in industrial, commercial, and agricultural applications. The clear-span design creates wide, unobstructed interior space - perfect for storage, machinery, production areas, or vehicle workshops. Built to withstand heavy loads and harsh weather conditions, these steel buildings deliver reliable long-term performance.

Available with a choice of cladding materials and colours to suit your site requirements.

Cold-Rolled Portal Frame Buildings - Kit Form Option:

Looking for a cost-effective solution? We supply cold-rolled portal frame buildings in complete kit form with detailed installation manuals. These lightweight, galvanised steel structures are ideal for workshops, storage buildings, and agricultural sheds. The reduced weight means lower foundation costs, making them a practical choice for smaller-scale projects.

Supply Options:
  • Complete kit for self-installation (full instructions provided)
  • Supply and installation service
  • Groundworks and base preparation available
