Mental or circular stairs. Be between 900mm and 1100mm above the floor or the nosing of a stair tread. Most of our industrial stairways have a tread depth that is between 10 and 14 inches with risers between 6 and 75 inches in height to comply with OSHA standards. In addition all of our stairs are generally wider than 22 inches and come with handrails if appropriate. The depth from front to back of a tread less any overlap with the next tread above see paragraphs 11 and 12.
The top edge of the top guardrail must be 42 inches plus or minus 3 inches above. For the measurement of the going on tapered treads see. The Australian standards for stairs and landings state that you can use a maximum of 18 stairs risers in a single flight. Flights can be connected using landings.
