Clear parking side

No column at the parking edge — easier access and less damage risk.

Single foundation line

One row of pads or ground screws keeps civils work small.

Falling canopy

Rear height above the eave sheds water to the gutter on the low side.

Row flexibility

2–12 bays per row; rows can step with the kerb line.

Overview

The single-side cantilever carries one row of bays from a single column line. The parking side stays open, which makes reversing, door opening and cleaning easier than a portal frame with columns at both edges.

The rafter is a tapered or straight H-beam welded to the column, with the rear height above the eave so the canopy falls away from the parking bay. Purlins run across the rafter at the module spacing and the gutter sits on the low side.

It is the usual choice for boundary parking, narrow service yards and staff bays along a fence, where a double-sided frame would not fit.

Workshop & site

Built around the parking bay

The column line is set first, then the rafter is lifted and bolted to the column head. Purlins and rails follow, and the gutter is aligned to the downpipe positions. Because there is only one foundation line, the civils and erection sequence stay short.

Options

What can be tailored

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

Parking direction

Nose-in or reverse-in; the canopy can overhang the bay by an agreed amount.

Bay width

2.4 m, 2.5 m or 2.7 m; accessible bays on request.

Finish

Hot-dip galvanised, primer, or powder coat in a RAL colour.

Drainage

Gutter and downpipe on the low side, connected to the site drainage plan.

EV readiness

Charger post or bracket at the column, with cable tray under the purlins.

Protection

Wheel stops, bollards and column guards for high-traffic bays.

Questions

Common questions

Why choose a cantilever?

It keeps the parking side free of columns, so drivers reverse into an open bay and doors open against nothing. It also needs only one foundation line.

How long can one row be?

Typically 2–12 bays per row. Row length is usually limited by transport and site layout rather than the structure; longer runs are split into frames.

Where does the water go?

The canopy falls to a gutter on the low side, with downpipes at agreed column positions and a connection to the site drainage plan.

Can it be installed on an existing car park?

Yes, provided the base plates and foundations can be built without disturbing the parking layout. A phased installation can keep part of the car park open.
