Customers from around the globe protect their harvested crops with high quality grain covers. Australian wheat growers call these bulk covers. Farmers in the UK call them sheets. Wherever you are the need is the same. Everyone wants to protect their harvested grain crop to assure their ability to market it at the best time. Wheat, corn, barley, soybeans, rice, almond hulls, whole cotton seed, and various other commodities are regularly stored under these bulk commodity or grain pile covers.
