Our Products

Now WA’s Leader in Sealed Silo Grain Storage & Aeration.

Guaranteed sealed silos made stronger to last longer with a 20 year structural Warrantee.

Store your grain in top condition, cool and dry and eliminate insect infestation by using our custom built aeration system. See below what makes DE Engineers the ‘Leaders’ in Silo manufacturing.


Guaranteed longer lasting sealable silos.

Rural Silos:

Longer lasting silos
Silos from 3-86 tonne

Our 3-90 tonne Silo bases are made from longer lasting hot dipped galvanised pipe with fully welded “Zincalume” base sheets (not riveted & guaranteed not to fail), steeper top and bottom cones, and are fitted with our unique, easy to use “Snap Tight” remote opening lid system. Not only can we boast the longest lasting silos made from more corrosive resistant material but we also use the thickest and strongest wall sheeting in the industry.

Meets and exceeds Australian standard AS2628 – Sealed grain storage silos.

Built to Aust Standards
Stronger silo bodies

No ‘Pop’ rivets are used in the construction of our silos, we use ‘lock Stem’ rivets as used in the aircraft industry with a high tensile mandrel that breaks off inside the rivet for extra strength. The air riveting system we use is much faster in construction and is one way that we can keep our prices down. Our body section is stronger and is one of only a few that meets AS ‘3774-1996 Loads on bulk solids containers’. Not only do we exceed the standards by making the silo walls stiffer, we add an extra 20% to the wall thickness.

152t Spiral silos
Spiral silos from 109-152 tonne

Our 152 tonne spiral silos have revolutionised grain storage in WA by being the largest fully sealed transportable grain silos in Australia. These larger capacity silos have bases made from Zinc plated square tube and because we don’t recommend placing square tube on the ground we use 12mm thick hot dipped galvanised plates to lift the tube off the ground to reduce corrosion.

NB/- Small marks or scratches on the sides of the spiral silos can occur because they have to be lifted by crane and slewed into position. These scratches are only cosmetic and do not affect the silos strength. The same profile is used in our 260t silos.

Less handling
Sealable and aeratable larger silos

Many customers who have previously used rows of 76 tonne silos are now using larger silos, saving time and money. The biggest advantage in using the larger silos being: three 50 tonne road train loads can go in or out of the silo before the auger needs to be moved, greatly reducing handling.

Double Silo Transport
Extra long silo trailers

DE Engineers ‘extra long’ silo trailers can transport 2 x 105 cubic metre silos at a time making them the most cost effective silos for grain storage. Built ‘Extra Long’ to accomodate the taller base and roof angles used on our silos which allow better grain flow and more storage. ie: our 2530 bushel silo has more capacity than our competitors 2700 or 2800 bushel (or model) silos, so always check the cubic volume.

Splayed Silo Legs
Customise your silo

DE Engineers silos can be customised to suit farmers requirements. Silos can be built with wider openings for large auger hoppers, higher outlets and we can also raise the height of the outlet opening handle with a universal joint to stop sheep from spilling grain. Some customers have specific requirements as per the placements of ladders and openings and as these may have changed over the years please check our standard layouts (Silo Footing Specs / Parts).

Safer, more comfortable ladders
Our latest silo innovations:

Innovation is what DE Engineers is renowned for. Even our safety cages are unique, being made in one piece for extra strength to reduce flexing and can be split down the middle and laid flat for transport.

'Snap tight' remote opening lids
New lid opening system

Lid systems have evolved but we have always tried to make them easy to operate sometimes with spring closing devices. While earlier lid systems were hard to maintain gas pressure our “snap tight’ lids are easy to use with just the right geometry to make them open and lock closed with the least amount of effort. Now we can guarantee all of our silos Meet and exceed Australian standard AS2628 – Sealed grain storage silos.

Longer hoppers, less mess.
Plastic Hoppers

We now have longer silo hoppers (1200mm long) available to reduce forward spillage on larger augers. They are light, easy to use, won’t rust and strap on to your mobile auger so there is no need to climb under silos when out-loading. Please let us know which size hopper you prefer and how many you require ($25 nominal fee when purched with silos).

Designed in WA for WA farmers
Silo aeration

Aeration keep your grain cool and dry, avoids spoiling and stops weevil activity. This is why we offer you the best of both fumigation and aeration. Some of our customers have eradicated weevil infestation completely by using our custom designed GrainSafe Aeration controller.

See more information on our Aeration page.

'Hopper Mate'
New innovation in silo hoppers

Smaller, lighter silo hoppers are easier to use and have less grain left inside when the job is finished. Our latest innovation is the ‘Hopper Mate’ which straps on to the auger barrel and the silo hopper preventing grain from being pushed forward, spilling on to the ground.
Nb/- Raising the hopper as high as possible under the outlet will prevent grain spilling over the sides.

Touch button unloading
Under silo conveyors

We are currently designing silos for use with belt or drag link conveyors with rates up to 200t/hr. The drag link conveyors can have an incline to fill trucks and can be driven with an electric motor or tractor PTO.
