Shed Alliance offers an extensive range of quality steel garages to house and protect your motor vehicles, sports equipment and garden tools.

No matter what your requirements, Shed Alliance can design and manufacture the perfect garage for your unique situation and site conditions. You can choose from our standard garage designs, or we’ll work with you to customise the dimensions, style, roof pitch, and colours to enhance and add value to your property.

Whether you need a single or double garage (or perhaps even larger,) a gable or skillion roof, or additional features like awnings, an attached carport, insulation, whirlybirds, skylights, vermin proofing, internal partition walls, or a mezzanine floor, our expert team can guide you through the entire design process, ensuring you get exactly what you need at the best possible price.

And don’t worry about sizing. Shed’s Alliance supplies garages from 3m wide to 24 m wide clear spans and wall heights to 6m. Standard roof pitches include 10, 15, 20 and 25 degrees to suit all purposes.

We manufacture all our garages from tough galvanised BlueScope steel C-sections and connection plates, then pre-punch them ready for easy DIY assembly. Our heavy duty knee and apex connection plates are supplied in thick galvanised steel and bolt together with a minimum of 8 M12 bolts per plate ensuring your garage is built to last and able to withstand the harsh Australian climate.

Standard inclusions have all buildings supplied fully flashed with colour matching screws and 2700 mm wide roller-doors where possible or you can choose your own width to suit from a big list of sizes.

Our streamlined manufacturing process along with detailed instructions and specifications, allows handy homeowners to assemble a steel garage over a weekend. But if you don’t have the time, tools or skills to erect the garage yourself, we can help arrange the construction process as well.

In addition to the colours, there are various sheeting profiles and thicknesses that are available to you when designing your shed:

corrugated Corrugated

This is the famous BlueScope Lysaght corrugated profile, equally at home with traditional and contemporary design. It is long, wide, strong, lightweight and economical in profile which can be quickly and easily aligned. Add up these features and you have a steel roof or wall cladding that simply offers outstanding value.



Trimdek is a subtle square-fluted steel cladding, available in long lengths, so on most jobs you can have one sheet from ridge to gutter without end laps.




Multiclad is a low-rib wall sheet which provides a cost effective solution to covering the walls of your shed.

In addition to the normal steel and sheeting required to build a shed or carport, there are a range of additional extras available which can be

We have an extensive range of roller-doors in all sizes for both domestic and industrial purposes. All Colorbond colours are available.




Personal Access-Doors


You can add multiple PA doors to your shed. All doors are usually 2040mm x 820mm and can come with locksets if needed.






There is a range of fixed sized windows available for your shed in all Colorbond colours. If needed you can add security screens or fly screens to your windows.




Glass Sliding Doors


If your shed is also your office, you may wish to add a glass sliding door. Glass doors are available in a fixed amount of sizes in all Colorbond colours. Security screens can also be added.






There is a range of ventilation options available to add to your shed. Whether you need a way to cool the workshop in summer or you are working with chemicals, a solution is available.






If you are going to be working in your shed a lot, you may wish to insulate the roof from the heat of summer, or cold of winter.




Vermin Flashings


A vermin flashing is an excellent way to stop mice, rats or snakes getting into your shed between the edge of the slab and the wall sheets.




Roller Door Motors and Remotes


You can add a motor and remote to your roller-doors so they open and close automatically. No one wants to get out of the car to open the door in the middle of a storm.




Mezzanine Floors


A mezzanine floor can be added for additional storage room in your shed. A great place to store that tent that never gets used.




Attached Awning


You can add an awning or lean-to to the side of your shed to park the car. Awnings can also be enclosed with sheeting if needed.
