The first step in building a GE silo is making the cone.
We start by welding together flat sheets of 1.6mm Zincalume. The combined sheet is then formed into a cone shape ready to be fixed into a steel frame.
Every cone is built by hand, meaning we can build almost any cone configuration, such as any cone pitch or an offset cone (where the outlet is off-centre).
At the same time we are building the frame.
While the cone is being shaped, we start building the frame of the silo. Most frames include one or two rolled steel rings connected by a specified number of RHS legs depending on the size of the silo.
Our frames are one of the most oft-customised parts of the silo; with many customers asking for outlet height and frame feature changes.
Next we connect the cone to the frame.
The cone is now attached to the frame, forming the base of the silo. Then the manhole, outlet, and bag chute are attached, along with any other attachments for the base.
We have a range of standard chutes and outlets, but more often than not we are building the silo with a unique set of attachments chosen by the customer.
We're already constructing the roof!
While you've been watching us put the base together, we've already started on the roof. Galvanised sheets are cut into cake-slice-shaped sections, shaped with valleys and ridges for water runoff, painted and assembled.
By carefully managing the flow of silos in the workshop, we've increased output from 3 to 8 silos per week over the last decade.
Now the silo takes shape as we add the wall sheets.
Onece the roof is assembled, we start attaching wall sheets. Starting from the top – attached to silo the roof – we make our way to the bottom, with a jig supporting the weight of the silo as we work.
We use a specialised machine to roll out wall sheets in the exact circumference needed for this silo.
Almost done: now we attach the upper silo to the base and finish it off.
The suspended walls and roof are now drilled and riveted to the base and final attachments added. It is at this stage that we add sight glasses, blower pipes, ladders, and any other attachments.
Our build process has been refined over 44 years with the hard-won knowledge passing down from mum and dad to the next generation.
The day has arrived! We're delivering your silo today!
The silo now receives a final quality check and is loaded onto a tipper trailer for delivery. We do all our own deliveries, and install your silo on site so that it is ready to go from day one!
