Mainline Sheds is a family owned and operated company that manufactures and distributes Mainline Sheds AUSTRALIA WIDE. There are a number of distribution locations throughout Australia, allowing Mainline to bring the best sheds to our clients nationally.



Mainline Garaports combine the security of a garage with the versatility of a carport – all under the same roof.

Commercial & Industrial Sheds

Commercial & Industrial

Mainline Commercial and Industrial Buildings are built strong. We custom design and build large, high quality industrial and commercial sheds for every purpose.



Create space and add value with a Mainline Garage. A Mainline Garage is the ideal place for the home handyman, storage or somewhere to park your pride and joy.



Barns are a fantastic storage solution for machinery, vehicles and equipment. They can also be a secure housing solution for livestock and farm animals. Ask us about our Mezzanine floor options for even more room.



Mainline’s extensive range of carports will give you the perfect addition to your property. They come in all shapes and sizes to suit both home and commercial environments.

Rural & Farming Sheds

Rural & Farming

Mainline Sheds can custom build a large new shed or steel structure to suit your purpose and location. Built tough, our Australian made rural sheds withstand the demands of farm life and the harsh Australian climate.
