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 *9 m³ to ****6 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 **5g/m2, **0g/m2, **0g/m2 hot-dip galvanizing coating steel sheets. All our flat silos are designed, manufactured and installed in accordance with D****7 or ASTM D****9 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 purpose. The flat bottom silo is equipped with flat repairing doors, outside ladder and ladder guard rings.

Shelley Brand flat bottom silos are composed of silo roof, manhole, roof handrail, natural vent, inside and outside ladder, ladder safety guard, inside and outside stiffener, silo door, door platform, sweeper, bucket elevators, dust collectors, temperature moisture controller, storage level indicator and storage control system.  All of them are integrated into the seamless system to keep you  grain storage automatic, safe, efficiently and effectively. All parts are made with standard and high quality materials in the strict process and quality control. The following are some of them.

The top of flat bottom silo adopts umbrella frame and the frame material is made of C model straight carbon steel with zinc coating, which is equipped with natural ventilation windows, manhole, ladder and safety guards. The ceiling is made of galvanized steel tile plates. If the sealed roof diameter is less than *2m, the roof angle is  *5º. Otherwise, the sealed roof angle is  *0º .

The steel flat silo body is designed and manufactured with hot-dip structural galvanizing steel plates with high elastic tolerance and stainless coating. These plates are rolled into corrugation and made into standard connecting holes. These plates and stiffeners are connected by high-strength screw bolts to form the corrugated silo body to keep the flat silo strong and durable.

The cement cone base will be applied to automatically unload stored products when the capacity is big and silo diameter is less than *2m. The half-cone base or flat base will be constructed when the silo diameter is more than *2m. Half-cone base cant completely unload the stuff, it needs to unload stuff  with a spiral sweeper. Cement base has a mediate  price and a long construction period.

Sweeper (also called clear dragon) is designed and installed to pick up the remains of stored products and provide good flow through gravity (like wheat, maize, barley, grains and granules, etc.) in the bottom of the flat silos. It automatically starts up once the gravity flow has completely finished. It will clean up the remained material at a rotation of **0º inside the storage silo.
