This 75 Ft tripple silo is an example of many to be found all around Australia. We used 70mm pvc storm water pipe as the silos. They are easily cut with a drop or compound saw. You can go to your local hardware store and purchase them. Easier than me supplying and you paying extra. If your really disperate than we’ll supply the tubing for an extra $30.00. Simple to construct, just watch the gluie fingure markes as i did. Model foot print is 232 mm x 80 mm and stands 310 mm high. It will dominate the area as silo’s do.
