What aluminium buys over steel
Aluminium does not rust, ever, and it comes powder-coated in a factory finish that holds its colour under Pretoria's high-UV sun without fading or repainting. It is lighter than steel, so the posts and beams look slimmer for the same span, which is why architects and estate design panels in Silver Lakes, Waterkloof and Menlyn Maine specify it. The trade-off is price and, on very wide spans, a slightly heavier section to match steel's stiffness.
| Aluminium | Steel | |
|---|---|---|
| Rust | Never | Galvanise/coat to prevent |
| UV colour-hold | Factory powder-coat, no fade | Chromadek / powder-coat |
| Look | Slim, modern | Sturdy, traditional |
| Single price | R12,000 – R22,000 | R6,500 – R14,000 |
Aluminium, sun and hail
An aluminium carport still needs the right roof to shade and to stop hail — the frame is rust-proof and UV-stable, but a shade net or thin polycarbonate roof on an aluminium frame will neither cool a car properly nor protect it from hail. Pair the aluminium structure with IBR-profile aluminium or impact-rated polycarbonate; the shade-and-hail reasoning is the same as for steel carports and is set out in the sun, heat and UV guide.
Where aluminium makes sense
Aluminium earns its premium in Pretoria East — estates with strict design codes, the embassy homes of Waterkloof, and modern glass-fronted builds where the carport is on show from the street. On a plot or a value Moot stand, a galvanised steel carport gives the same protection for less. Compare both on the carport prices in Pretoria page.
Common questions
How much is an aluminium carport in Pretoria?
An aluminium carport in Pretoria costs from R12,000 for a single and R22,000–R40,000 for a double, supplied and installed — about one and a half times an equivalent steel carport.
Is an aluminium carport better than steel?
Aluminium never rusts and holds a factory powder-coat finish through Pretoria's UV, which suits estates and homes where looks matter. Steel is stronger for the price and, when galvanised, lasts for decades. Both need a solid, impact-rated roof to shade and protect a vehicle.
Does aluminium fade or rust in the Pretoria sun?
An aluminium carport does not rust, and its factory powder-coat finish holds colour under Pretoria's high UV far better than a painted steel frame. The frame is durable; hail and heat protection still come from the roof sheeting fitted to it.
