As an alternative to large, open-pile storage, Geometrica, Inc., Houston, Texas, U.S., specializes in the design, manufacture and installation of large-span enclosures. Because most grain storage piles are naturally conical in shape, a circular dome is a perfect match for permanent, large-capacity storage, the company said. Material does not come in contact with the structure, so no damage is done to the grain or the enclosure. With enclosures from 150 to 1,000 feet in diameter, nearly any capacity can be met. The use of stacking or reclaiming machinery is easily accommodated, as well as front-end loaders or other material handling equipment.
