Clear-span steel portal frame interior of a completed warehouse building
Steel Structures

Steel Warehouse and Workshop

Clear spans to 36 m with no internal columns — so racking aisles, crane runs and turning circles are decided by your operation rather than by the structure.

Product overview

What It Is and What It Does

A pre-engineered steel building is designed, cut and drilled at the factory so that site work is bolting rather than fabricating. For a warehouse or workshop that matters twice: the frame goes up quickly, and the geometry is right because it was machined, not measured on site.

Clear spans reach 36 m without internal columns. That is the number that decides what the building can do for the next thirty years — racking layout, overhead crane runs, vehicle turning circles and future reconfiguration all depend on an uninterrupted floor.

Frames are supplied hot-dip galvanised or shop primed, complete with purlins, bracing and bolts, with insulated roof and wall cladding options for climate-controlled operations.

Key benefits

What You Get From It

An uninterrupted floor

Clear spans to 36 m mean the racking and the traffic plan are not designed around columns.

Bolt-up erection

Members are cut and drilled at the factory, so no site welding is needed to make the frame.

One complete package

Purlins, bracing and bolts are supplied with the frame rather than sourced separately.

Corrosion protection specified

Hot-dip galvanised or shop primed to suit the exposure at your site.

Problems it solves

The Situations This Product Answers

Columns in the wrong place

A column that blocks a racking aisle or a crane run costs capacity every day the building operates.

Site welding on a schedule

Welding a frame on site is slow, weather dependent and hard to inspect. Bolting is none of those.

Parts sourced from three suppliers

Frame from one, purlins from another, bolts from a third is how a building ends up incomplete on erection day.

Corrosion in coastal or industrial air

Specifying galvanising up front is far cheaper than repainting a frame in service.

Getting It Right on Site

Start from the operation, not the building

Racking layout, crane runs and turning circles set the span and eaves height.

Send dimensions or a sketch

Building dimensions are enough to get drawings, a spec sheet and a fixed price back.

Specify corrosion exposure honestly

Coastal and industrial atmospheres justify galvanising; inland dry sites often do not.

Check the foundation interface early

Holding-down bolt layouts must be cast correctly before the steel arrives.

Buyer questions

Steel Warehouse and Workshop FAQ

What buyers ask before placing an order for this product.

What is the maximum clear span?

Clear spans reach 36 m without internal columns. Longer spans are engineered on request against your loading.

Is site welding required?

No. Members are cut and drilled at the factory for fast bolt-up on site.

What is supplied with the frame?

The building comes complete with purlins, bracing and bolts, plus erection drawings and a bolt schedule.

Can the building be insulated?

Yes. Insulated roof and wall cladding options are available for climate-controlled operations.

How do you handle snow and wind loading?

Frames are engineered to AS/NZS, EN (CE) and the wind, snow and seismic loads you specify for the site, with load-test reports supplied per order.
