Stair Stringer (Junior Channels) Channel Basics

A36 stair stringer channels are specially designed to support steel stair stringers. They run along the sides of risers and treads to prevent the stairs from tilting or collapsing.

Steel channels, as opposed to wood or aluminum, are frequently used in commercial stairs to withstand constant and heavy traffic. A36 stair stringers are also called junior channels. They have flat and parallel flanges, whereas C channels have tapered flanges.
