About this detail

A typical stair guardrail and handrail assembly is supported by a stair stringer and hollow structural section framing. Concrete-filled steel pan treads with steel plate risers form the stair carriage, incorporating stair nosings with luminous egress markings. The guardrail stands at a minimum of forty-two inches above the finished floor, constructed with one-and-a-half by one-and-a-half-inch hollow structural sections and one-and-a-quarter-inch diameter pipe rails. A continuous handrail is positioned at thirty-six inches above the finished floor, featuring required extensions at the top and bottom of the stair run. A minimum head-height clearance of six feet eight inches is maintained along the diagonal walk line.
