Double carport materials and specs compared
| Material | Strengths | Watch out for |
|---|---|---|
| Steel lip channel frame, 2 mm | Standard frame for double carports | Rusts at scratches unless coated |
| 76 × 76 mm square tube posts | Concreted into the ground | Footing depth decides stability |
| IBR sheet, 0.47 or 0.5 mm | Common roof; galvanised or Chromadek | Chromadek adds about R3 500 on a double |
| Aluminium frame | Does not rust; quoted 25–35 years | Roughly 15–25% dearer than steel |
| HDPE shade net | Cheapest cover; lets air through | Replace every 3–5 years |
Span and posts
- A standard double is 6 m wide by 6 m long.
- Posts beside the bays can clip doors, so check where they sit.
- Residential cantilever overhangs typically run from 3 to 8 m.
- Extra width of 6.5 to 7 m suits wide vehicles or side storage.
Footings and ground
- Posts are concreted in, so footing depth decides how stable it stays.
- Cantilever footings are often 1.2 to 1.5 m deep.
- Slabs suit heavy roofs and cantilevers; pavers may still need concrete footings.
- On existing paving, ask for a check of pipes and cables below.
Roof and drainage
- Flat roofs cost less but need a proper fall to drain.
- Pitched roofs shed water better and cost about a third more in steel.
- IBR sheet thickness runs from 0.3 to 0.8 mm, so ask which.
- Gutter and downpipe add roughly R850 to one supplier's steel double.
Approval for double carports
- A standard 6 × 6 m double covers 36 m², under the 40 m² minor work cut-off.
- Minor work skips plans, yet the building control officer must still authorise it before you start.
- Doubles over 40 m², triples and enclosed sides usually need full plans.

Frequently asked questions
How much does a double carport cost in 2026?
Expect from R10 450 for shade net up to about R37 400 for steel, mostly excluding VAT. Cantilever and pitched designs sit higher.
Is a double carport cheaper than two singles?
Yes. Unlike two single covers, the bays share one row of posts, so you pay for less steel and labour.
Do I need council permission for a 6 × 6 m double carport?
Yes. An open double of 36 m² is minor work, but permission comes before building. Above 40 m² expect full plans.
Should I choose a cantilever or a four-post double?
A cantilever gives open entry but costs roughly 25–40% more. Four-post is cheaper and simpler to build.
How long does a steel double carport last?
Well-built galvanised steel lasts about 15 to 25 years with upkeep. Shade net needs replacing sooner, around every 3 to 5 years.
