Most often, the value of the grain (in dollars-per-tonne) is usually greater than the cost of the structure in which it is stored. Minor expenditure in improving the quality of the storage can thus be quickly recovered if commodity losses are commensurably reduced.
Bag silos are a cheap solution for grain storage but its use has some limitations and disadvantages over the storage in steel silos: Steel silos keep the grains safe longer, have greater storage capacity in a much smaller area, are recommended to store high moisture grains, avoid humidity problems and are easier to unload.
Using steel silos to store the grain instead of using warehouses provides many advantages, such as less ground space, optimum storage conditions for the grain, lower assembly costs and less expensive overall.
