Features and Advantages Flat bottom silo can support more capacity, which up to 10000tons, and cheaper than hopper bottom silo. And it need a sweep auger to run the grain out.   1. Lower basic cost with lightweight, low request for foundation, low consumption of steel. 2. We can produce the standard components which can be installed on-the-spot. 3. Simple, easy and efficient to install within a short amount of time due to superior component design which are connected by standard bolts. 4. Easy to remove or repair with standard bolts. 5. Low cost and long tenure of use. The cost of bolted silo is just 35%-50% of the cement silo with the same specification; and its life span can reach 30 years.   Silo structure 1. The Silo Body   Include the wall plate, column, manhole, roof ladders and so on. (1) The wall plate  Our steel is hot galvanized, which makes it durable and weather resistant. Our advanced bolts with spherical washer and the resisting-worn rubber are used to ensure the tightness and using period.   (2) Column   The column, made by the Z-bar, is used to reinforce the silo body. It is connected by junction panels.  (3) Manhole and Roof Ladders  There are inspection door and ladders inside and outside the silo body. It is convenient and accessible for any maintenance work.   2. Roof   Roof is made up of radiated beam, roof cover board, tension ring, ventilator scoop, roof cap, etc.   The space age construction technology, which is adopted in the design of the silo framework, can ensure the stability of silo under the large span. There is a guardrail around the silo eaves and there is also a manhole on top of the roof.
