Model # 60S

This is a code compliant, 60" diameter stair that is three stories high. The handrail is # 200 - 1 ½" round 16 gauge tubing. The main and center balusters, spaced less than 4" apart to be code compliant, are # 302 – 1" square 16 gauge tubing. The treads are a # 133 – radial grate with a 30 degree run at the widest point. The treads are made out of a 3/16" A-36 grade steel material. The center column is made from a 3 ½" I.D. schedule 40 round pipe. The stair has a factory finish of hot dip galvanize. The stair was built three sections for easy shipping and then was bolted back together at the job site.
