About this detail

An HSS 14x4x1/4 tube steel stringer is painted black and receives a 1 1/2" by 3/8" shaped steel plate welded and centered on the vertical face, ground smooth, and painted black. A 2" concrete infill fills the typical steel pan and riser stair system, welded at seams and to angle clips at each stringer, with exposed bottoms painted. An L2"x2" steel angle is painted where exposed and supports the assembly. A 3/4" Ipe wood tread with a satin finish and 1/2" prefinished round nosing profile sits atop the infill.
