Housed in a steel cap and secured with a wire band, the bristles on these brooms resist pulling out during aggressive sweeping of heavy debris. Stiff bristles push heavy, wet, and hard-to-move material on asphalt and rough concrete such as street pavement. Bristles resist most acids, oil, and chemicals, making these brooms suitable for industrial and municipal maintenance. A protective sleeve at the base of the handle guards against wear from rough surfaces.
