400,000 m² of livestock housing: what a project that size changes about supply.

A pig housing project at 400,000 m² is not a greenhouse. It is a steel structure programme with a repeatable unit, and the discipline it teaches is repetition.

What was supplied

Columns, truss chords and diagonals, purlins, bracing and the roof drainage line, all cut and punched to a repeating module. At this area the module is the product: one bay design repeated thousands of times, with the jig and the punch pattern fixed at the start.

What the project taught us

Repetition exposes a tolerance error faster than any inspection. A 3 mm error in one bay is invisible; in bay 400 it is a frame that will not close. That is why the first-off check and the fixed punch pattern exist as a rule on every project now, not just the big ones.

It also taught us to separate coating decisions by member. Buried or wet-interface members need hot-dip; roof purlins in a dry position were supplied pre-galvanised. One coating class for everything is a lazy specification and an expensive one.

Relevance to an export buyer

This case proves volume and repetition, not greenhouse design. If your project is a livestock shed, the same logic applies — but the code is yours.
