Steel is the most common garage door material in Alberton for a straightforward reason: it gives the most door for the money and it takes hard use. From the older single garages through Alberton North, Florentia and Raceview to the wide doubles in Brackendowns, Meyersdal and Mayberry Park, most of what we replace is steel and most of what we fit is steel.

Galvanised and coated finishes
Every steel door we supply is galvanised before it is coated. In Alberton that matters more than average: on properties closer to the industrial belt, bare steel under a scratch will start to go within a season. Galvanising underneath means a scratch stays a scratch rather than becoming a rust line down the panel.
Coating specification near the industrial belt
Where a house sits close to Alrode, we will recommend a heavier coating than the standard finish and explain why. It is a modest cost difference at purchase and a large one over the life of the door, and it is the single most common reason we see steel doors here failing earlier than they should.
Gauge, span and stiffness
A wide double in a light gauge flexes, tracks badly and wears its rollers. We specify the gauge and the reinforcing for the span rather than defaulting to the same panel for every opening.
Insulated steel garage doors
An insulated steel door is stiffer, quieter and far better where the garage is a workshop, a gym, an office or a flatlet. On west-facing garages through Brackenhurst and Meyersdal the temperature difference is easy to feel, and the extra stiffness helps on a wide opening.
Security on a steel garage door
Panel strength is only part of it. The locking, the track fixings and, on a motorised door, a drive that holds the door down are what stop a door being lifted. We fit anti-lift arrangements as standard on automated doors.
Steel or aluminium
Steel is stronger and cheaper; aluminium is lighter and does not corrode. On an ordinary Alberton street, steel with a good coating is the better buy. Nearer the industrial belt, or on an exposed ridge position, aluminium often earns its extra cost. We give you both prices and the reasoning.
What a steel garage door costs in Alberton
The most cost-effective door for most openings. Priced on width and height, panel profile, insulation, coating and automation, after an on-site measure.
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.
