Grain Sheds


Maximise your profits with a quality heavy duty sealed grain shed that provides the ultimate on-farm multipurpose storage solution!

WRL Engineering in Warren has designed, manufactured, and installed quality heavy duty sealed grain sheds on-farm for more than a decade throughout NSW and QLD. With quality and innovation at the core of every project, WRL strive to continually refine the design and installation methods to improve the sealing properties, and to reduce the time it takes to install on-site.


WRL Engineering grain sheds are superior to tarpaulins and other lower cost methods due to the solid impenetrable barrier to vermin. They are not vulnerable to rips or tears like plastic sheeting and other materials.


WRL sheds are a popular long-term solution built to last. They are an outstanding multi-functional storage solution and can be used to store machinery, various grains, fertiliser or can be used as another work area.

Australian certified innovation patent no 2022100124.

“We personally manage every job from beginning to end. We have worked over many years to create and develop a fully sealed grain shed that has now become a patent pending design. We are vertically integrated and have complete control over the manufacture of all components and assemblies for your shed. This allows us to manufacture faster, and with more quality assurance than many others.” Warren Lefebvre, WRL Engineering.

With evenly placed fill inlets along the roof of every WRL fully sealed grain shed, you can fill from the top easily with your auger of choice. Maximise storage space by filling from the top allowing your grain or legumes to fill more of the shed.

Check out this video of recently built sheds in Surat QLD, that were put straight to work, being loaded at up to 350 tonnes per hour.


All our fully sealed grain sheds have a concrete bund along the length of the shed. This makes grain handling quick and easy. It also protects the shed from damage and seals out vermin.

Move your grain quickly and easily in a fully sealed grain shed! Check out Rob moving 55 tonne of grain into a road train in 20 minutes! That's around the same time as a conventional auger!! So easy. 


We are often asked how we make sure our sheds are sealed. Every sheet within our grain sheds is sealed during construction to ensure a quality fully sealed grain shed at the end of each build.
