Industrial stairways provide safe and secure access to upper-level areas and mezzanine floors. They are considered a safer alternative than vertical ladders. Industrial stairways are a fixed option and are suitable to use in a range of environments. All industrial stairways we supply at Shelving + Rack Systems are compliant with Occupational Safety and Health Association (OSHA) and American National Standards Institute (ANSI) requirements.
The main designs of industrial stairways are straight – no top landing, top tanding- right angle, L-shaped, U-Shaped 180° turn, and spiral stairways
Straight – no top landing stairways provide direct access without any turns or changes in direction to the top platform. As they are straight, visibility is unobstructed from the bottom to the top landing plate.
Top landing-right angle landings are used to have the stairway parallel to the mezzanine or area they are accessing. They do not protrude out into the floor area.
L-shaped stairways provide a landing at the turn in the stairway. They provide a resting platform while climbing, and usually fewer steps to climb on each incline. L-shaped stairways are well suited to corners. They can also offer a degree of visual privacy between floors.
A 180° turn U-shaped stairway provides a larger landing at the turning point between two runs of stairs. Like the L-shaped stairway, U-shaped stairs provide a midway resting point. They use less linear space.
Spiral stairways are also an option for permanent access to upper levels and are good space savers. Revolving around a center pole, they can provide compact access to mezzanines and loft spaces.
Exit options from landings include side exits, rear exits, and all directional exits.
Overall heights of industrial stairways range up to whatever the application requires. Heights 144” and above require a mid-landing.
Typical uses for industrial stairways provide safe access from one floor to another, up to mezzanine levels, to areas such as the back of trucks, docks, tanks, platforms, high-tier shelving in warehouses or storerooms, or large machinery and equipment.
Gradients of industrial stairways are 38 degrees; others are available.
Most stairways are 36” w. Options for step widths of 24”, and 30”, 42” and 48” are also available. When choosing a width, allow for fitting and installing parameters appropriate to your environments and space available.
Other Safety Features
Step depth and riser height must comply with OSHA requirements for foot placement, and the end user of the stairway. There are variations in requirements for industrial stairways versus those which are accessed by the general public.
Any stairway with more than four steps must have handrails. Handrails on industrial stairways provide users a rail to hold onto for balance and support when ascending or descending to reduce the risks of falling.
Slip-resistant treads help protect from accidental slips and falls. Types of slip-resistant treads include embossed galvanized treads, serrated grating, bar grating, perforated steps, and grip strut.
