Agricultural
Weather-resilient bulk storage, silos, and processing facilities engineered to protect high-value agricultural assets against extreme climate conditions.
What Agricultural Projects Demand From the Steel
The problems clients bring us most often on this kind of project, and how the steel package answers each one.
Bulk storage that must stay dry and ventilated
Clear-span frames with the roof and wall envelope quoted together, with ventilation openings and drainage located at design so stored crops and feed stay dry.
Corrosive atmospheres from feed, fertiliser and moisture
Coating systems and envelope materials are chosen for the environment of the building; fixings and flashings are specified to match.
Processing lines and cold rooms inside a steel hall
Column grids follow the process layout; insulated panels and door openings for cold rooms are detailed with the frame instead of added later.
Remote sites and seasonal deadlines
Members are match-marked for bolted erection and shipped in erection sequence, so a local crew can raise the hall between seasons.
How Your Project Is Built
Three phases from the first drawing to handover. Move over a phase to see what happens in it and what you receive at the end of it.
Engineering & Foundation
The structure is sized in a 3D BIM model before any steel is cut. While members are fabricated in the factory, earthworks and independent foundations are poured on site in parallel from the anchor bolt templates we ship first.
- 3D BIM model before any steel is cut
- Anchor bolt templates shipped first
- Foundations poured in parallel with fabrication
Fabrication & Erection
Columns, beams and trusses are CNC-cut, welded, tested and trial-assembled in the yard, then shipped in erection sequence. On site the frame is bolted from marked members with the erection drawings and our remote or on-site guidance.

- Shipped in erection sequence
- Bolted on site from marked members
Envelope & Handover
Cladding, insulation, openings and rainwater goods close the building; dimensional and coating records are handed over with the as-built drawings and the certificate package.

Recommended Product Systems
The structural systems we fabricate most often for this kind of project. Each opens the product page with sub-systems, parameters and FAQ.
Pre-engineered buildings on a steel portal frame, the rigid frame building type of every PEB catalogue: tapered H-section primary frames, cold-formed purlins, bracing and anchor bolts detailed as one system for workshops, warehouses and agricultural halls.
Solar panel racking and mounting structures for ground-mount and rooftop arrays: racking frames, brackets and mounts, mounting rails, and the agrivoltaic greenhouse frames that carry crops below and modules above.
Building envelope systems quoted with the steel frame: roof and wall cladding, insulation and waterproofing, industrial doors, windows, louvers and ventilators, gutters and downspouts.

Frequently Asked Questions
Is a steel portal frame the same as a pre-engineered building?
In our scope, yes. A pre-engineered building (PEB) is a portal frame structure whose primary frames, purlins, bracing and connections are engineered and fabricated as one kit. The Portal Frame Structure page covers the complete building; this page lists the sub-systems and components we also quote separately.
Do you quote portal frame buildings without drawings?
Yes, from the footprint, eave height, span, crane capacity and site location. Our engineers issue a preliminary BOM and tonnage; full shop drawings follow once the design basis is agreed.
Which design code do you fabricate to?
Whichever your design specifies. We work to AISC 360 or Eurocode 3 (EN 1993) for design intent, and execute to EN 1090-2 EXC2 under certificate 2787-CPR-01627. State the code in your enquiry and the quotation is issued against it.
Can you issue calculations our building authority will accept?
Yes. We provide English structural calculation reports with load combinations and 3D models. Where local regulations require a licensed local engineer to stamp the drawings, we supply the calculation package for their review.
What is a realistic lead time?
For a typical single-building scope the standard cycle is 40 to 50 days: 1–2 weeks from contract to 3D models and shop drawings for your approval, then 4–5 weeks for procurement, CNC fabrication, welding, coating and loading. Drawing approval is the part you control.
Do you supply the enclosure as well as the frame?
Yes. Roof and wall cladding, insulation, waterproofing, doors, windows, ventilation and drainage are quoted as one package — see Enclosure & Cladding Systems . Single-source supply removes the interface risk between frame and envelope.
How do we verify your certificates?
Ask us for the certificate together with its Document of validity — they are issued as an inseparable pair. We send both with the welding annex on request. Details are published on our certificates page .
