Stair units are available in perforated, serrated, and textured surfaces to help improve your footing and provide easier access to work platforms, scaffolding, moving steps, and portable stairs. They’re constructed in a variety of materials, load capacities, step widths, and climbing angles to meet most applications. Grainger has a selection of stair unit handrails to help provide stability and support when ascending or descending stairs. They can be installed to help provide continuous hand railing on straight flights or geometric staircases. Additional stair accessories provide added flexibility to help you customize your stairway, portable steps, and moving stairs.
