Round Silos

PETKUS Round Silos are practical for all types of grain, oilseeds, feed and industrial pellets. They consist of corrugated galvanized sheet steel which undergoes the Sendzimir process Z600 to provide high corrosion protection. The modular design of the round silos allows heights from 1 to 25 m and diameters from 3 to 32 m. The specifications of PETKUS steel round silos are calculated according to the product loads of ANSI/ASAE or EURO CODE. The construction is carried out in accordance to EUROCODE construction standards.

The roof of the silo is a self-supporting structure made of trapezoidal segments and equipped with ladders, filler caps and skylight observation. Round silos are equipped with inspection doors and wind rings and can also be equipped with roof and floor ventilation systems, a thermostat and a fill level sensor, resting platforms, railings and walkways.

PETKUS round silos are offered as flat bottom, hopper and loading silos. Flat bottom silos are used for long term storage, and are emptied with the help of a sweep auger according to the "first in, first out" principle. Hopper silos are emptied at a hopper inclination of 45° or 60°, depending on the properties of the product. Loading for trucks or railcars can with accomplished with a drive under loading cell.
