A steel tube stair stringer lands on a supporting steel beam with a coped end at the bearing location. A one-quarter-inch-thick steel closure plate caps the end of the stringer, joined with typical complete joint penetration and fillet welds. The concrete slab and metal deck feature a blockout at the stringer bearing location to accommodate stair tread installation.
