Straw Building Construction 101

摘要

Straw is the annually renewable agricultural by-product of cereal grain, which is often burned as waste. The grains include rice, wheat, oats, and barley. Most of the available straw in the western United States is from wheat, where a great deal of wheat is grown along the Colorado River. Baling machines, or balers, are used to convert the loose straw into bales. The bales generally are of two sizes. Two-string bales are approximately 14 inches high, 18 inches wide, and 36 inches long. They weigh 40 to 50 pounds and are found mainly in the northern and eastern states. Three-string bales are approximately 16 inches high, 24 inches wide, and 48 inches long. They weigh 70 to 80 pounds and are found predominantly in the southern and western states.
