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 Colorsteel 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.
