A metal silo is a structure which is designed for the purpose of bulk materials storage. It may be temporary or permanent, depending on the setting. The classic image of a metal silo is the grain or silage silo used in farm to store bulk grain and silage. However, the metal silos are used in many other field to hold a wide variety of material. Silos are used all over the world for storage of bulk materials, these material as seed, animal feed, grain, flour, cement, pellet, etc.
The metal silos are cylindrical construction which is made from stainless steel sheet. The volume of the metal silo varies, depending on the diameter and the height, but the structure can usually accommodate a lot of material. Loading and unloading is done with automated systems which move goods in and out of the silo.
In all cases, silos provide a dry, controlled, secure environment for goods. They can be used to store materials until they are needed, to keep a reserve or supplies on hand, or to aggregate materials from a group for easy pickup. For example, in a farming community, multiple farmers might pool grain into a single large silo at harvest so that buyers for the grain can simply go to the silo, rather than needing to travel from farm to farm to collect the grain. Farmers are compensated at a rate determined by how much grain they loaded into the silo.
