What aluminium buys over steel
Aluminium does not rust, ever, and it comes powder-coated in a factory finish that holds its colour under Highveld UV without repainting. It is lighter than steel, so the posts and beams look slimmer for the same span. On the East Rand that matters most in the humid industrial belt, where a low-maintenance frame avoids the rust upkeep a painted structure needs near heavy industry — and at Bedfordview and Edenvale homes where the carport is on show. The trade-off is price, and on a value or plot market steel usually still wins.
| Aluminium | Steel | |
|---|---|---|
| Rust | Never | Galvanise/coat to prevent |
| Finish | Factory powder-coat | Chromadek / powder-coat |
| Look | Slim, modern | Sturdy, traditional |
| Single price | R12,000 – R22,000 | R6,500 – R14,000 |
Aluminium and hail
An aluminium carport still needs the right roof to stop hail — the frame is rust-proof, but a shade net or thin polycarbonate roof on an aluminium frame will not protect a car from an open-veld storm. Pair the aluminium structure with IBR-profile aluminium or impact-rated polycarbonate; the hail reasoning is the same as for steel carports, where the gauge-and-pitch detail is set out.
Where aluminium makes sense on the East Rand
Aluminium earns its premium at Edenvale and Bedfordview — the region's upmarket pocket — and on airport guesthouse frontages that must stay maintenance-free. On a plot or a value stand across the rest of the metro, a galvanised steel carport gives the same protection for less. Compare both on the carport prices in Ekurhuleni page.
Common questions
How much is an aluminium carport in Ekurhuleni?
An aluminium carport in Ekurhuleni 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 aluminium worth it over steel on the East Rand?
Aluminium never rusts and needs no upkeep, which suits Edenvale and Bedfordview homes and the humid industrial belt where a painted frame would corrode. On a value or plot stand, galvanised steel gives the same protection for less, so most East Rand jobs stay steel.
Does aluminium stop hail?
The aluminium frame is durable, but hail protection comes from the roof. An aluminium carport must be fitted with impact-rated IBR-profile aluminium or polycarbonate sheeting to stop open-veld hail — a shade net roof only shades.
