No-where is sole-gripping design more critical than on stairs, where feet are more prone to slip, often with severe consequences. Heavy Duty Grip-Strut® stair treads provide the sole-gripping qualities of Heavy Duty Grip-Strut® safety grating for extra safety in two ways: multi-directional scraping action of tiny-toothed surfaces keeps shoes clean; open design rids surface of debris. The open area also makes threads easy to see, and edges read well from above.
Heavy Duty Grip-Strut® stair treads are available in standard nosing style only, 10-gauge steel: one depth (2”), two widths (91/4”, 133/4”), and four standard spans (24”, 30”, 36”, 48”), with others available upon request. Ideal for new construction, or easily attached to stringers for rehabilitation of existing stairs.
