The main types of garage doors

Garage doors are sorted by how they open, and that one detail decides how much room each needs. A roller door is a steel curtain that rolls into a drum above the opening. B&D says it made the first one, the Roll-A-Door, in 1956.

A sectional door, which plenty of people know as a panel lift, is a run of panels that travels up on tracks and then back along the ceiling. A tilt door is one piece that swings out and up. Side-sliding, side-hinged and bifold doors open sideways instead of up.

Steel garage doors and the other materials

The big makers start with coated steel. Steel-Line names BlueScope Colorbond and Zincalume steel as its preferred roller door steel, B&D makes its Panelift sectional doors from Colorbond steel, and Gliderol says its doors are predominantly Australian BlueScope steel.

Garage door design sits on top of that: the panel profile, the colour and the finish. Steel-Line sells its sectional doors in Flatline, Slimline, Glacier, Ranch and Heritage profiles. Past plain steel there are timber-look finishes and real cedar, and aluminium, acrylic, polycarbonate and doors with windows.

Picking a type for your garage

Start with the space and work back to the look. Check the headroom above the opening, the wall either side and the depth inside, then compare them with the sizes and room each door needs. If the garage is a room you use, read about insulated garage doors before choosing a finish, since insulation is listed for sectional doors by both B&D and Steel-Line.

Questions people ask

What is the difference between a roller door and a sectional door?

Where the door ends up. A roller door rolls into a drum above the opening and leaves the ceiling clear. A sectional door slides back along the ceiling on tracks, so it needs ceiling space but less room above the opening.

Are all garage doors made of steel?

No, though steel is the usual starting point. Steel-Line sells Western Red Cedar doors, and both B&D and Steel-Line make doors in aluminium composite and acrylic.
