Colorbond is a colour range, not a door type
Colorbond is BlueScope's range of coated steel in set colours, and B&D, Steel-Line and Gliderol all build doors from it. A Colorbond garage door can be a roller door, a sectional door or a Flex-A-Door: the name tells you the steel and its colour, not how the door opens.
Steel-Line names BlueScope Colorbond and Zincalume steel for its roller doors, with BlueScope its preferred supplier. B&D makes its Panelift sectional doors and its Flex-A-Door from Colorbond steel, and Gliderol says its roller doors come in a wide range of Colorbond steel colours.
Garage door colours and finishes by maker

White, black and everything in between
Whether you want a white garage door, a black one or a soft grey, the real question is which range carries that shade on the door type you want. If an exact paint match matters, Steel-Line offers more than 70 Dulux colours, though on its sectional doors only.
Windows narrow the choice. Steel-Line fits them only to its Ranch and Heritage profiles, and only in standard Colorbond colours, so a window door in a custom shade is a question to raise early.
Colour, coatings and the coast
If you live near the sea, read the warranty before you choose. Steel-Line's excludes installs within 800 metres of the sea, and Gliderol's 7 year corrosion cover on its roller curtains does not apply within 800 metres of a high salt concentration.
Steel-Line's coastal care article adds that homes many kilometres inland can still see faster corrosion, so the washing below is worth doing wherever you are.
Keeping a Colorbond garage door looking right
- Hose down the parts rain never reaches, such as the top of the door, at least every six months. BlueScope asks for it more often where there is salt spray.
- Use clean water and a cloth, keep sunscreen off the coating, and never wash the opener, Steel-Line says.
- Near the coast, Steel-Line suggests lubricating the door at least twice a year, or every three months for the longest life.
- Clean off dirt promptly: Steel-Line's warranty excludes damage from grime, chemicals and pollutants that were not removed.
What we would do
If the door has to match a Colorbond roof, fence or gutters, give the door specialist the colour name rather than a photo, because phone screens shift colours. If nobody knows the name, ask for samples to hold against the roof or fence in daylight.
