On-ground Silos


Cyclone Logo

Featuring advanced design including a heavier gauge steel sheets at the base, a wide corrugation profile to reduce the risk of internal obstructions, and a specific roof slope, a SilOz on-ground silo can maximise the amount of grain stored. 

Gwydir has a wide range of SilOz on-ground silos, from 24 to 48 feet in diameter. 

Standard designs are able to store between 218 and 1,743 tonnes of wheat, but what sets SilOz silos apart is their unique ability to be upgraded to increase capacity as your storage needs grow. 

SilOz on-ground silos are strong and stable. The wide corrugation profile of the galvanised steel walls reduces the risk of internal obstructions, limiting the risk of “hang-ups” which can harbour insects and fungi and lead to grain spoilage or downgrade. We can also install aeration systems for your SilOz Silo to help maintain grain quality. 


SilOZ silos have been proven to be one of the most effective sealed silos on the market in Australia.

Built to Australian Standard 2628, all SilOz silos comply to meet this definition of gas-tight, sealable silo which is suitable for fumigation after meeting a half-life pressure test. With the cost of fumigation so high, this feature provides peace of mind for growers.  

SilOz can also design customised on-ground silos to store 2,000 to 5,000 tonnes of grain upon request. The Gwydir Group team can come to your farm to help you determine the best solution for your site and ensure it complies with Australian Standards and local building regulations.

SilOz can provide model specific design review statement and certified foundation construction drawings which may be used to support any council DA requirement.
