Stair treads and risers are made to withstand some of the most abusive traffic known to our industry. Since they are so tough, cutting stair treads is very difficult and must be handled carefully. Extra care must be taken not to allow the cutting instrument to slip and cause an injury.
Stair tread types and preparation. There are two types of stair treads: the two-piece individual tread with separate riser, and the combination tread and riser (Photo 1). The preparation of the stairs must be done with the utmost care. Since the treads are subjected to a severe amount of traffic, it is important to achieve a good bond. Note that the nose of the tread has a slight rounding to help stop severe stress to the nose of the tread (Photo 2).
