About this detail

Galvanized steel stair treads attach to a C12x20.7 galvanized steel stair stringer with three-eighth inch diameter zinc-plated bolts, two washers, and a nylock nut. Each three-foot-long stair tread consists of welded bar grating with a checker plate nosing per specification. The assembly provides a ten-inch tread depth, a nine-inch riser height, and a fifteen-sixteenths-inch nosing projection.
