Amstep 700 Series Renovation Stair Treads were originally developed for mass transit stairways and can withstand severe impact and extremely heavy traffic without cracking or delaminating. Their unique walking surface consists of a special non-slip resistant formulation, bonded to a heavy duty extruded aluminum base. The non-slip surface maintains its integrity for the life of the tread.
Amstep 700 Series Renovation Stair Treads will not absorb dirt, liquids, or common contaminants and can be easily cleaned with routine cleaning procedures.
Choice of colors
The abrasive material bonded to the heavy-duty aluminum base of the 700 Series is offered in your choice of eight attractive colors. These colors can blend with any decor, for improved esthetics. The color pigment is incorporated into the abrasive material itself, so the color will never fade or peel.
