Fertiliser silos

Polem’s fertiliser silos are manufactured from fibre-glass reinforced plastic and were specially developed for the storage of fertilisers in the arable farming sector. The specific spray-wrap process results in a smooth and seamless interior wall that guarantees excellent outflow properties.

Added to that, the Polem chemical fertiliser silos are renowned for their long life span and excellent quality.
