Commercial Bin Specifications Continued >>

NOTE:

Cubic Meters based on 28 degree angle of repose.
Specifications and design are subject to change without notice.
All commercial bins are designed for the storage of grain and other free-flowing materials weighing up to 52 lbs. per cubic foot.
Maximum bushel capacity based on 6% compaction.
Maximum storage capacities reflect grain peaked on center, using an angle of repose of 28 degrees.
Other ring heights for 30 degree slope roofs.
Peak heights shown for 30 degree slope roofs.

Typical Grain Densities:
Wheat approximately 800 kg/m^3 (50 lb/ft^3);
Corn approximately 721 kg/m^3 (45 lb/ft^3);
Rice approximately 640 kg/m^3 (40 lb/ft^3);
