Model # 60S

This stair is one of our most popular line rail stairs we manufacture. This spiral stair is 60" in diameter and is code compliant. The line rail system has 9 lines with less than 4" spacing between the rails. The top rail is a # 200 - 1 ½" round, 16 gauge tubing; the intermediates rails are a ¾" round steel solid bar. The line posts are ½" x 2" flat bar at every quarter turn of the stair. The stair treads are made out of 3/16" thick checker plate steel. This stair was manufactured with optional closed risers. The center column is made from a 3 ½" schedule 40 I.D. pipe. The landing (not shown) is made out of the same material as the stair treads. The balcony rail is built to match the line rails used in the stair. The stair was shipped with a red oxide primer finish and was painted on the job site by others.
