Steel is the default garage door across most of Pretoria and it deserves to be. It is strong, holds a finish, takes knocks better than aluminium of the same thickness, and costs less than any premium alternative. Most of what we fit on the Pretoria housing stock is steel, and for the majority of properties it is the correct answer rather than a compromise.
Why steel garage doors suit most Pretoria properties
- Strength for the money. Nothing else gives the same resistance at the price.
- Dents less readily than aluminium, which matters on a family driveway.
- Wide finish range, including profiles that read as timber from the street.
- Manageable weight, so operator and spring sizing is straightforward.
Corrosion protection on steel garage doors
Steel rusts if the coating fails, and it fails at edges, fixings and the bottom rail where water sits. On a Pretoria door the bottom section takes storm splash and driveway run-off, which is exactly where we see doors fail. Galvanised substrate with a proper powder coat, and correct fixings that do not react against the coating, is the difference between eight years and eighteen.
Insulated or single skin steel garage doors
Single skin is fine for a detached or unheated garage. If the garage is integral to the house, doubles as a room, or sits under a bedroom, an insulated double-skinned door is quieter and more comfortable and usually worth the difference. Insulated doors are heavier, so the operator is sized accordingly.
Steel garage door repairs and panel replacement
Sectional steel doors have individually replaceable panels, so vehicle damage is a repair. Rust confined to the bottom section on an otherwise sound door can often be dealt with rather than replaced. We price the repair alongside the replacement and tell you which we would do.
Steel garage door finish options
Dark colours run hot on a west-facing Pretoria elevation and show marks more. We tell you where a lighter or textured finish will age better, and bring samples to the survey.

Common questions
About steel garage doors
Between 0.5mm and 0.8mm galvanised sheet. The gauge is the specification that matters most — thin sheet dents when something falls against it. We quote the gauge on every proposal so you can compare offers on the same basis.
Chromadek is a factory-applied coil coating: tough, consistent and hard to beat for durability. Powder coating lets us match any RAL colour to the trim on your house. Both go over galvanising, never over bare steel.
Only if the coating is breached and left. It starts at the bottom rail, where the door stands in driveway water, and around fixings. We use galvanised bottom rails, seal cut edges and fit a proper bottom seal. Inland a maintained steel door runs well over a decade.
We do not work that way. Older South African garages are rarely square, and forcing a stock-size door into an out-of-square opening is what leaves the daylight gap down one side. Every door is built to the measured opening.
