Zincalum steel grain storage silos serve as airtight spaces where cereals are safe to store for several decades for their controlled internal temperature. Cylindrical shaped storage silos are available in different capacity, weight and diameter based options. Spacious interior area and necessary ventilation arrangement of grain storage silos promote enough air permeability inside to prevent decay of stored grains. Cross- sectional roof structure, thermally insulated housing, seismic effect protected design, compact shape, space saving capacity and moisture free grains storage arrangement are some of the important features of these storage silos.
