Wide clear bay

Up to 7 m per side with a deep rafter and curved column.

Curved tapered column

Welded from plate, galvanised as one piece, no sharp knuckle.

Continuous rows

Repeating frames with expansion joints where the row requires them.

Service-friendly

Gutter, downpipes and cable routes integrated into the frame line.

Overview

The long-span carport uses a curved tapered column and a deep rafter to clear bays up to about seven metres. The curve carries the load into the column without a sharp knuckle, and leaves a clean silhouette along the row.

Frames repeat along the row at the module spacing, with purlins at 1,134 mm in the standard layout. The column is welded from plate to the tapered section shown on the drawing, then hot-dip galvanised as one piece.

It suits front-of-building parking, retail and transport sites, and rows where the client wants fewer columns and a wider, more open canopy.

Workshop & site

A row that reads as one line

The tapered column is the visual signature of the row, so the frames are jig-welded to keep the curve consistent. On site the columns are set and plumbed first, the deep rafters are bolted, then purlins and rails run the full length of the row.

Options

What can be tailored

The frame, finish and electrical interface are set before fabrication — not adjusted on site.

Span

5.8 m to 7.0 m per side, confirmed against wind and snow load.

Column finish

Hot-dip galvanised as standard; powder coat in a RAL colour on request.

Bay width

2.5 m to 2.8 m; wider accessible bays on request.

Drainage

Gutter along the row, downpipes at agreed frames, leaf guards optional.

EV readiness

Charger brackets and cable tray integrated into the frame line.

Fascia

Aluminium or steel fascia for branding and lighting.

Questions

Common questions

What is the maximum span?

The standard drawings cover 5,900 mm per side with a 3,180 mm ridge; the range is 5,800–7,000 mm. Final sections are engineered to the local wind and snow load.

Why a curved column?

The curve transfers the rafter load into the column without a sharp welded knuckle and gives the row a cleaner profile. The column is welded from plate and galvanised as one piece.

Can rows run the full length of a car park?

Yes. Frames repeat along the row and the run is split into transportable frames, with expansion joints where the design requires them.

How is it shipped?

Knocked down: columns, rafters, purlins, rails and fixings are bundled and loaded into containers, with each bundle marked to the erection drawing.
