What we make

Portal frame steel structures

A portal frame is a rigid steel frame — column and rafter joined into one continuous member — that gives you a clear-span building with nothing standing in the floor. It is the most economical way to roof a large area in South Africa, and it is all we have made since 1999.

By use

Four things we build most often.

Warehouses & storage
Clear-span portal frames for storage, distribution and industrial floors — racking-ready, forklift-ready, extendable along the ridge.
View warehouses & storage →
Farm sheds
Implement sheds, packing sheds and grain storage — clear span for machinery, doors sized to your largest implement.

Aircraft hangars
Clear-span frames for private and light-commercial aircraft — the span, the eaves and the door opening are what set the design.

Carports & shade structures
Free-standing or lean-to covered parking and shade — for homes, fleet yards, lodges and schools.

Everything else

And a great deal besides.

Since we started operations in May 1999 our customers have used our steel fabrications for all of this — and for a mine monorail, a set of football stands, a skylight for a house in the DRC and a Corten-clad office cantilevering out of a spec house.

If you arrive with an engineer's or architect's drawing, we will quote to it.

Standard specification

What every structure includes.

Roof sheeting: Galvanised IBR profile sheeting as standard, on a 10° roof pitch.
Fasteners: All fasteners included, down to the foundation bolts — nothing to source separately.
Design: Every structure is designed by a civil engineer. An engineer's drawing and certificate is supplied on request.
Fabrication: Manufactured in our own Spartan factory in Kempton Park, not subcontracted out.
Delivery & erection: We deliver and erect throughout South Africa using our in-house erection team, or supply delivery-only for export and owner-erected jobs.
Custom sizes: The nine sizes below are the sizes we hold designs for. We custom-manufacture any size to suit the site.

Options

Specified at quoting stage, because several of them change the frame design rather than just what gets bolted to it.

Chromadek sheeting: Colour-coated roof and side cladding where appearance matters or a spec calls for it.
Bullnoses: Curved bullnose eaves detailing, common on retail and residential structures.
Translucent polycarbonate sheeting: Roof-light panels that cut daytime lighting load in warehouses and workshops.
Ventilators: Static or turbine ventilators to move heat out of workshops and packing sheds.
Roller shutter doors: Sized to your vehicle or plant access, fitted during erection.
Bubble foil roofing insulation: Reduces radiant heat gain and condensation under the sheeting.

Standard sizes

Nine sizes, or anything else.

These are the sizes we already hold designs for, which makes them quicker and cheaper than a one-off. Anything outside the list is custom-manufactured.
