- Roll-up, sectional or tip-up
Steel is the most common garage door material in Centurion for a straightforward reason: it gives the most door for the money and it takes hard use. From the older single garages through Lyttelton Manor, Valhalla and Zwartkop to the wide doubles in Amberfield, Thatchfield and Rooihuiskraal North, most of what we replace is steel and most of what we fit is steel.
Steel garage doors we supply in Centurion
- Steel sectional doors in ribbed, panelled and flush profiles.
- Insulated steel doors with a foam core for garages used as rooms or workshops.
- Steel roll-up doors for low-headroom garages and out-of-square openings.
- Timber-look coated steel where an estate wants the appearance without the maintenance.
Galvanised and coated finishes
Every steel door we supply is galvanised before it is coated. That is what keeps a scratch from becoming a rust line down the panel, and on a low-lying property where the bottom of the door sees damp it is the difference between a door that lasts and one that does not.
Matching an estate colour specification
Steel takes a powder-coated finish in effectively any colour, which is what makes it the practical answer on estates with a fixed door colour. We match to the specification and supply it in writing for the architectural committee before manufacture.
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, because the wide doubles common in the newer Centurion estates are where a thin panel shows up fastest.
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. The noise difference is the one people notice, particularly in a cluster where the garage shares a wall with a bedroom.
Steel doors on openings that have moved
Where a house has settled and the reveal is no longer square, a rigid steel sectional door will bind. We check the opening at survey and either correct it or recommend a steel roll-up curtain instead, which tracks happily in an opening a panelled door cannot cope with.
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.
What a steel garage door costs in Centurion
The most cost-effective door for most openings. Priced on width and height, panel profile, insulation, finish 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.
