About this detail

Stair section at the bottom landing, anchored by a concrete slab and supported by steel channel stringers with concrete-filled treads and typical painted steel risers. A guardrail assembly is mounted along the stair, incorporating a 1-1/2" diameter painted steel handrail, 3/4" diameter painted steel rods, and a 5/8" x 2" painted steel flatbar. The handrail is positioned between 34" and 38" above the stair nosing treads, while the guardrail extends 42" to the top. Required extensions of 12" plus the tread depth are maintained at the bottom nosing.
