- Extruded aluminium, stainless fixings
- Powder-coated, anodised or woodgrain
- Sectional, tip-up or roll-up slat
An aluminium garage door is light, does not rust, and takes a finish well. Cape Town is the market where that second point stops being a talking point and becomes the reason to buy one, because on a coastal property aluminium removes the failure mode that ends most steel doors.
Aluminium garage doors we supply in Cape Town
- Aluminium sectional doors in flush, ribbed and slatted profiles.
- Glazed aluminium doors with full or partial glazing panels.
- Aluminium roll-up doors for low-headroom garages.
- Anodised and marine-grade powder-coated finishes in a wide colour range.
Why aluminium wins near the sea
Within a few hundred metres of surf, a coated steel door is in a race against its coating and the coating eventually loses. Aluminium does not corrode in the same way, and with anodising or a marine-grade powder coat it holds its appearance for years with nothing more than washing. On the Atlantic seaboard, Blouberg, Hout Bay and the False Bay coast it is frequently the cheapest door over ten years despite costing more on day one.
Hardware still has to be right
An aluminium panel on ordinary steel tracks, hinges and fixings is a door that will still fail, just in a different place. Stainless or heavily coated running gear is part of the specification, not an extra, and it is the detail that separates a proper marine installation from a repainted one.
Weight and what it saves
A lighter door loads its balance components and its operator less, which means smaller motors, longer hardware life and quieter operation. On a wide double that difference adds up over years of daily cycles.
Glazing and daylight
Aluminium sections carry glazing well, and a glazed upper row turns a dark garage into a usable space. On a property with a view, a glazed aluminium door can keep some of it.
Stiffness on wide, wind-exposed openings
Aluminium is lighter than steel and needs more section to reach the same stiffness. On a wide door facing the south easter it will flex and drum if the profile is chosen on price, so we specify a heavier profile or a reinforced section on exposed elevations.
Insulation, and the honest limitation
Bare aluminium conducts heat readily, so a single-skin aluminium door is not an insulated door. Where the garage is used as a room we fit an insulated core with an aluminium face and quote it as what it is.
What an aluminium garage door costs in Cape Town
More than steel and less than timber at purchase, and frequently the lowest cost over the life of the door on a coastal opening. Priced on opening size, profile, glazing, finish, hardware grade and automation.
Common questions
About aluminium garage doors
On the coast, yes — it removes rust as a failure mode entirely. Inland it comes down to weight and looks: lighter doors are easier on the motor and springs, and aluminium is what makes a full-view glazed door possible. Inland, on a budget, coated steel is honest value.
A single-skin one does, and it will radiate into the garage. Where the garage is attached to living space or has been converted, we specify foam-filled aluminium sections with a thermal break, which performs close to an insulated steel sectional.
Wash the face with clean water and mild detergent two to four times a year, more often at the coast, and rinse out the tracks and bottom seal while you are there. No repainting, no rust treatment, no annual reseal.
Yes. A woodgrain sublimation finish gives a convincing timber appearance with none of the recoating. It is what we usually recommend for rental properties and for doors in full sun where nobody will maintain real timber.
