- 0.5mm to 0.8mm galvanised sheet
- Chromadek or powder-coated to any RAL
- Roll-up, sectional or tip-up
Steel is the most common garage door material in Benoni for a straightforward reason: it gives the most door for the money and it takes hard use. From the older single garages through Northmead and Westdene to the wide doubles in Rynfield, Crystal Park and Brentwood 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 a town this humid that is not a nicety: bare steel under a scratch will start to go within a season, and mist off the water keeps the bottom of a panel damp long after sunrise. Galvanising underneath means a scratch stays a scratch rather than becoming a rust line down the door.
Coating specification near the water
On the lakeside and low-lying streets we 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 most common reason we see steel doors in Benoni failing earlier than they should.
Gauge, span and hail resistance
A wide double in a light gauge flexes, tracks badly and wears its rollers, and a thin face is also the one that dents in a hailstorm. We specify the gauge and the reinforcing for the span and the exposure 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 or a room. In a damp town it also cuts the condensation that forms on the inside of a cold single skin, which is what rusts tools and ruins anything stored against the door.
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 Benoni street, steel with a good coating is the better buy. On a lakeside stand, aluminium frequently works out cheaper over ten years. We give you both prices and the reasoning.
What a steel garage door costs in Benoni
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.
