Applicable Building Codes

  • IBC/International Building Code
  • ADA/American Disabilities Act

Guardrails and handrails are designed within the parameters of the building codes and field conditions of each project. They can be used separately or together. Models 03 and 04 comply with IBC Industrial code, which requires an inside handrail in addition to a guardrail.

  • Default is guardrails on both sides.
  • Guardrail may be eliminated for stairs against a wall. Stairs without guardrails have a narrower stringer.
  • Guardrails extend 42" above nosing of tread and end at the top/bottom of the stair.

FULL BALUSTER GUARDRAIL

  • Commercial stairs have balusters spaced so that a 4'' sphere cannot pass between.
  • IBC industrial stairs have balusters spaced so that a 21'' sphere cannot pass between.
  • Balusters attach to stringers with provided bolts and spacers

FILLER PANEL GUARDRAIL

  • Optional filler panels replace full balusters.
  • Filler panels can be the same color as the stair or a complementary color.

Tread options are:

Diamond plate tread provides a solid tread surface with raised diamonds for a non-skid effect.

Concrete pan tread has a wrap-around front diamond tread plate nosing and arrives ready for site-poured concrete. Available in depths of 9¾'', 1015/16'' and 12⅛''.

Smooth tread has a solid surface designed for the installation of carpeting, non-slip flooring, or other flooring material directly to the stair and should not be used alone.

  • Iron gray powder coat
  • Gray primer powder coat
