Sizes & prices
Steel structures for sale: sizes and quotes
Compare nine standard sizes, then request a quote for the one that fits. Prices depend on the span, height, cladding and site requirements, so we cost each structure for its project.
Standard sizes
Nine sizes, already engineered.
Width is the clear span between columns. Height is measured to the eaves, not to the ridge. Every one of these is designed, drawn and ready to quote — which is why a standard size costs less and arrives sooner than a one-off.

Included as standard
Everything you get as standard.
- 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 on top
Priced per job. Several of these change the frame design rather than just being bolted on afterwards, so they belong in the enquiry rather than in a change order.
- 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.
Pricing
Every structure is quoted individually.
We don't publish a price list. Steel is a traded commodity, so the raw material moves week to week — and two buildings with the same floor area can differ enormously depending on span, eaves height, cladding, doors and site conditions.
Talk to us and we'll quote for exactly what you need. Send the span, length and eaves height if you know them, or just describe what has to fit inside and we'll work the rest out with you.

Questions
Cost & lead time.
Plans, foundations and specification questions are answered in the full FAQ.
What does a steel structure cost per square metre in South Africa?
We quote every structure individually, and the quote is free. Steel is a traded commodity, so the raw material price moves constantly, and the cost per square metre depends heavily on span, eaves height and how much cladding you specify — two buildings of identical floor area can differ enormously. Send us the size and the intended use and we will cost your building properly.
What makes one structure cost more than another the same size?
Span and height first — both add steel to every frame. Then cladding: an open structure is far cheaper than a fully clad and doored one. Then site conditions, since coastal and high-lying sites attract higher design wind loads. Then options — doors, insulation, ventilators, Chromadek. And finally whether we erect it or supply it delivery-only.
Is it cheaper to build in steel than in brick?
For large clear-span buildings, usually yes, and it is faster. A portal frame reaches a weatherproof shell in a fraction of the time masonry takes, needs no wet trades for the structure, and puts no loadbearing walls inside the floor area. For small buildings the gap narrows, and for anything where thermal mass matters the comparison is not really like for like.
How long will it take?
You get a programme for your job with the quote. Fabrication is rarely what sets the pace — plan approval and foundations usually are, so start those early.
