Aluminium Garage Doors

• Extruded aluminium, stainless fixings
• Powder-coated, anodised or woodgrain
• Sectional, tip-up or roll-up slat

Aluminium is the answer to two problems steel cannot solve: salt air and weight. It does not rust, it comes in around a third lighter than an equivalent steel door, and it takes a powder coat that holds its colour for years. On the coast it is not a premium option — it is the sensible one.

Where aluminium earns its price

• Coastal properties. Anywhere within a few kilometres of the sea, a galvanised steel door will show rust bleed at the fixings long before its time. Aluminium does not have that failure mode. This is why most of what we fit in the Cape Town and George areas is aluminium.
• Wide double openings. Less mass means a smaller motor, gentler wear on the springs and gear, and a door that does not sag in the middle over time.
• Full-view and glazed doors. An aluminium frame is what makes a glazed garage door possible. Anodised or powder-coated stiles with toughened or frosted glass infill panels — the look most often specified for a converted garage, a showroom or a modern home.
• Homes where the door is a design element. Aluminium takes horizontal slat, flush-panel and woodgrain-effect finishes cleanly, so the door can be matched to window frames or cladding.

How we build them

Extruded aluminium sections are cut and assembled to the measured opening. Frames are mechanically fixed and corner-braced rather than relying on adhesive, and every fastener is stainless steel — a plated steel screw in an aluminium frame at the coast will fail first and take the surrounding metal with it.

Finishes are powder coating to any RAL colour, anodising in natural or bronze, or a woodgrain sublimation finish for the look of timber with none of the recoating. Coastal installations get a marine-grade coating specification as standard.

Mechanisms

Aluminium doors are built as sectional doors, tip-up doors or roll-up slatted curtains. Sectional is the most common: hinged horizontal panels stacking under the ceiling, with full perimeter seals. Where headroom is tight we build the same door as a roll-up aluminium slat curtain instead. Tell us your headroom measurement and we will tell you which will fit.

Insulation and noise

Bare aluminium conducts heat, so a single-skin aluminium door in full sun 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 brings the door close to an insulated steel sectional on both heat and sound.

Motorisation

All our aluminium doors take standard sectional or roll-up operators, with soft start and stop, obstruction detection and battery backup for load-shedding. Because the door is lighter, the motor works less and the whole assembly lasts longer than the same setup on a heavy steel door.

Maintenance

Wash the face with clean water and mild detergent two to four times a year, more often at the coast, and rinse the tracks and bottom seal out at the same time. That is the entire maintenance schedule. There is no repainting, no rust treatment, and no annual reseal.

Repairs

We repair aluminium garage doors on any make: bent or dented sections, worn rollers and hinges, failed seals, seized motors and damaged bottom rails. Individual sections can usually be replaced rather than the whole door, and we can match most common finishes.

Send us the opening width and height, your headroom above the lintel, and how far you are from the sea. A consultant will come back with a costed option and an honest view of whether aluminium is worth it on your property or whether coated steel will do the job for less.
