A stair tread is a horizontal covering for a set of stairs in order to improve traction. These could be made from a variety of materials, such as wood, carpeting, or rubber. Colonial Mills braided stair treads are constructed with the same quality and process that you would find with any of our other products using high-quality polypropylene, wool and chenille yarns. Along with providing safety and traction, they also add texture and style to the stairs. A stair tread installation kit is available for purchase to easily install braided stair treads to the steps.
