Silo Tube


Silo Tube from Austube Mills is a four-sided tubular section without any equal length sides.

Silo Tube was designed for silo ring beams – the transition between the silo wall and discharge hopper. When used for this critical structural element, the inclined surface of Silo Tube follows the hopper angle whereas the other three surfaces remain horizontal or vertical. This allows for easy joining of the silo wall to the hopper plate via the Silo Tube section.

Apart from being used as a ring beam, Silo Tube can also be used as an economical alternative for silo support legs. Though designed for silos and bins, Silo Tube can also be used in various other applications which can exploit its different cross-section.
