Not sure what type of garage door you're after?

There are 3 types of garage doors: Roller Doors, Sectional Doors and Tilt Doors. Unfortunately we do not supply or install Tilt (one piece) doors.


Roller Doors - "Roll up into one big roll" Garage Doors.

These kind of doors are very common. The most non-technical way to describe a Roller Door is, "it rolls up into one big roll when it opens". A Roller Door

generally has a standard pattern and you can choose from a range of Colorbond Colours.


Roller Doors are best suited for garages that have plenty of "headroom" and enough height to spare. Roller Doors are also better for Carports as they have less structural requirements. In terms of prices, Roller Doors are slightly more affordable than Sectional Doors. However, if your garage door's width reaches 5 metres or more we would recommend Sectional Doors..


Sectional Doors - "Panel by Panel" Garage Doors

These are sometimes called the "Panel" doors. Sectional or Panel doors "open up section by section". They are the more popular type of garage doors. Sectional doors come with optional features such as glass windows and various patterns to choose from. Sectional doors typically come in 4 or 5 panels, "joined" together internally. The panel doors are dearer than Roller doors but you can choose from a few different patterns: squares, rectangles or just straight lines. You can also choose from a range from colorbond colours to suite your house existing colour scheme.


We would especially recommend Sectional doors for large garages. Roller Doors work best for carports or open, back lane entrance.
