This piece holds the treads and risers in place. The zig-zag support that goes up each side of the stairs is called the stringer. For open riser stairs, the gap where the riser would go cannot be more than 4 inches. Cut stringers can be spaced no more than 18 inches on center, so a 3-foot-wide staircase needs three stringers, and a set of slightly wider stairs (say 3 feet 6 inches) needs four stringers. Residential codes usually require that risers be no more than 7 inches high and no less than 4 inches. Handrails are not required on walking surfaces with running slope less than 1:20. In commercial applications, handrail is required on both sides of stairs and ramps. It is required on stairs with two or more risers and ADA ramps with a rise of 6'. The number of stringers you need is a function of the width of the staircase and the tread material. The purpose of a handrail is to provide guidance.
