Our bulk grain bins offer safe, dry feed storage and are available in 6′, 7′ and 9′ diameter sizes. All grain bins have 4″ wide corrugation reduces the resistance to downward flow of feed, feed hang-up and bridging. Industry test have proven that wide corrugation gives 25%more vertical strength than narrow corrugation, and almost twice the strength of bins with no corrugation. Wider corrugation results in wider bin sheets, thereby increasing capacity. The same width corrugated bin holds more bushels than a narrow corrugated bin.
