Flat bottom silos are commonly selected steel silos to storage bulk grains and other materials. Large volume storage is its typical feature, the storage volume of this type grain storage silo ranges from 39 m³ to 29726 m³. They are erected on flat or conical concrete foundations for long-term storage of large quantities of grain, seeds, pellets and granular products, etc. The flat bottom grain silos are made of high quality 275g/m2, 300g/m2, 350g/m2 hot-dip galvanizing coating steel sheets. All our flat silos are designed, manufactured and installed in accordance with D-4097 or ASTM D-3299 standards.
The Shelley Brand well assembled steel flat silos are made with high quality hot-dip galvanizing steel plates which are rolled into corrugation and made into standard connecting holes. These plates and stiffeners are connected by high-strength screw bolts to keep the flat silo strong and durable. The thickness distribution of the steel flat silo plates is distributed according to equal strength theory which makes the silo plates bear average stress. The vertical friction is support by the steel silo stiffeners. These stiffeners are evenly vertically distributes in the silos. The connecting screw bolts are served with round galvanized steel washers, the connecting holes are served with age-resistant and water-proof daub belts that are for aviation special purpo
