Span and columns
Every metre of clear span you ask for is bought with steel. So is every column you remove. There is a point where the honest answer is “keep a column”, and it is often earlier than expected.
I write about the decisions that decide cost and trouble on a steel warehouse, workshop or cold store — span, column spacing, eave height, crane duty, corrosion. The decisions you make before anything is drawn.
Most steel building projects do not fail in fabrication. They fail in the first three decisions.

A crane, a mezzanine, a silo, a suspended conveyor. Each one changes the frame before the frame exists. Adding them later is not a detail change, it is a new building.
Coastal air, wet processing floors, fertiliser dust, abrasive aggregate. The same shed lasts fifteen years in one place and five in another. This is decided at specification, not at maintenance.
The problems are specific to what you make, not to steel. Read the industry notes →
Crushing halls, conveyor galleries, maintenance bays, stockpiles under cover.
Wet floors, washdown, drains, and what that does to a steel frame over time.
Panels, vapour, floor insulation, and the joints nobody wants to detail.
Docks, ramps, truck turning, door counts — the traffic decides the building.
Pipe yards, racks, fire separation, and lifting clearances that cannot be faked.
Assembly, appliance, machining — the same shed, different service loads.
Written for owners and project managers, not for engineers.
Send me the span, length, eave height and what the building has to carry. I will tell you what I would change before you ask anyone to quote. No charge for the first look.
