This stairway provides access to a football practice facility observation tower. It is a 60" diameter stair and is approximately 40’ tall.
The stair was fabricated in one section and then spliced into three sections for shipment for reassembly at the job site. The treads are constructed out of 12 gauge checker plate steel. There are four 1" square balusters per tread for a minimum of 4" spacing per UBC code.
The handrail is a 1 1/2" round tubing. The center column is a 3 1/2" ID schedule 40 round pipe with lateral braces at the mid point. The stair was shipped with a red oxide primer with a coat of semi gloss black paint applied by the owner at location.
