Trevira fabric silos are the most appropriate solution for the in-shed storage of powdered, granular, and pelleted products; grain and livestock feed. Two versions of fabric silos are available: the STR model, which consists of two sets of pockets, and is suitable for floury products for mainly industrial use, and the SIT model, which has only one set of pockets, for light products and agricultural/livestock use. Both are made of high tenacity, durable and self-breathing fabric. They rest on a hot-dip galvanized iron frame. Capacities range from 2 Mc. up to 30 Mc.
