Agricultural & Farm Steel Buildings
Portal-frame steel for farm buildings, grain stores and livestock sheds. We design, fabricate and install agricultural steel structures to BS EN 1090 Execution Class 2.

















Frames that earn their keep on the farm.
Farm buildings ask a lot of a steel frame: wide clear spans for machinery and livestock, durability against a harsh rural environment, and a structure that goes up on a working farm with minimal fuss. We design, fabricate and install the portal frames and secondary steel for agricultural buildings, from general-purpose sheds and grain stores to livestock and equestrian buildings, all to BS EN 1090 Execution Class 2 and erected by our own teams. The steel is fabricated to your engineer's design and built to stand up to farm use.
Steel for buildings that work the land.
General-purpose, grain-store, livestock and equestrian frames, installed by our own teams.
General-purpose farm buildings
Clear-span portal frames for machinery stores, workshops and multi-use farm buildings.
Grain and crop stores
Steel frames for grain stores and crop storage, with the spans and heights the store needs.
Livestock and equestrian buildings
Frames for cattle, sheep and equestrian buildings, with clear interior spans for stock and handling.
Secondary steel
Purlins, rails and bracing that carry the cladding and keep the frame stable in exposed conditions.
Erection on the farm
Installed by our own teams, planned around the working life and access of a live farm.
Steel frames built for the farm and the weather.
Agricultural steel earns its keep for decades in a hard environment, so the frame and its protection have to be right. We fabricate the portal frames and secondary steel to BS EN 1090 Execution Class 2, finished to suit the rural setting, and install with our own teams around the working life of the farm.

Why farm steel has to last.
Agricultural frames work for decades in a hard environment, so the steel and its finish have to be right.

Questions clients ask us.
General-purpose and machinery sheds, grain and crop stores, and livestock and equestrian buildings, all as clear-span steel portal frames to your engineer's design.
Yes. Clear-span portal frames are what we fabricate for agricultural buildings, so the interior stays open for machinery, stock and handling.
Yes. Agricultural steel is fabricated and finished for durability in an exposed rural setting, coordinated with the corrosion specification for the building.
