These extra stiff brown poly bristles work well for moving large debris such as rocks and litter. This corn broom is great for agricultural, municipal, railroad, warehouse, and outdoor use. The wood handle is connected to a metal cap, which the bristles are riveted to after being heat sealed. Heat sealing keeps them breaking, fraying, or shedding. A steel band is then added to help the corn broom retain its shape. Please take a look at our complete line of brooms & dust pans for other corn brooms and some dust pans that way work well with different style brooms.
