SilOz formally known as Cyclone Silos Australian made since the 1970’s, exciting new phase of the Australian made silos.

Specialising in on farm flat bottom silos ranging from 400 up to 4750 tonnes in a corrugated galvanised finish. With specialised designs in sealing, Australian standard access systems, including spiral staircases, leading mechanical equipment.
SilOz silos are gas tight sealed to the Australian standards of AS2628 if installed to the manufacturer’s guidelines of installation.

The SilOz silo is designed and engineered to meet the Australian 1-in-200 year wind events.
Made in Jindera NSW & designed for the harsh Australian conditions to meet Australian grain industry needs.

SilOz grain silos are designed for the safe storage of cereal grains including wheat, oats, barley, canola, chick peas, beans and many other grain types.

Optimum Silos Pty Ltd is an Australian family-owned business, bringing you the premium SilOz brand which was officially launched in July 2023.
SilOz will continue to be committed to providing a trusted product to deliver sealed silos to the Australian grain industry.

SilOz silos are manufactured from galvanised high strength sheet steel and hot dipped galvanised accessories, making them strong and durable. With the increase in extreme weather conditions, Siloz offer 1 in 200 year event certification as standard.
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.

With the removal of the single desk and grain deregulation, farmers are building more silos to provide increased options for the marketing/selling of their grain. SilOz engage a group of experienced grain storage advisors (AgriDealers) who offer advice on the best solution to suit your specific requirements, as well as organise the complete erection and installation of your silo grain storage system.
The advanced design and heavier gauge steel sheets at the base mean that Siloz sealed on-ground silos are strong and stable. This, combined with a specific roof slope, maximises the amount of poured grain that can be stored, making SilOz the obvious choice for your on-ground grain storage needs.
