Industrial Stairways


Industrial stairways contribute to your warehouse’s access network, creating safe and efficient pathways and egress routes throughout your workspace. Industrial stairs grant access to mezzanines, landings, stories, pits or wells, roofs, machinery repair, product picking, platforms, and over trenches or equipment.


Warehouse stairs come in many shapes, sizes, and styles, including fixed industrial stairs, mobile stairs, ladders, crossovers, and more. Finding the perfect stair system for your warehouse can be challenging. Stairway features and regulations like handrails, stair width, and tread can add to the stress of selecting metal warehouse stairs.

Here are some standard features and things to consider when customizing your industrial stairs:


  • Stair material – steel, aluminum, stainless steel, galvanized steel
  • Stair tread – non-slip tread, tread depth, stair tread covers, anti-slip tapes
  • Stair stringers – provide load-bearing support for the treads and risers. Framework.
  • Handrails – railing fittings, railing thickness, railing material, extended handrails
  • Posts – post material, post thickness, OSHA-compliance
  • Platforms – decking and dimensions
  • Decking – extruded, slip-resistant, grip strut, fiber grate, bar grate decking options

Industrial and Commercial Stair Code Requirements

OSHA stair regulations govern system specifics such as handrails, stair tread, vertical clearance, riser heights, and stair depth. Before installing industrial or commercial stairs in your facility, study OSHA regulations and adhere to any local codes.


IBC stair codes fall under chapter ten, “Means of Egress.” The IBC is another regulatory agency to adhere to when designing and installing your industrial or commercial stairways.

Stair Width

According to the IBC, egress stairs should not be less than 44 inches (1118 mm). According to OSHA, the required minimum width for industrial fixed stairs is 22 inches.

Stair Capacity

OSHA standard 1910.24 states that fixed industrial stairs must be able to carry at least four times their maximum intended load.


OSHA and the IBC also regulate industrial handrails for stairs. IBC Section 1012.2 states that handrail height must be no less than 34 inches (864 mm) and no more than 38 inches (965 mm). Handrail extensions must return to a wall, guard, or another handrail to provide continuous support in the transition between the railing and a level surface. 

Cost of Metal Warehouse Stairs

A typical straight-run OSHA or IBC staircase to a second-story landing, mezzanine, or floor can cost anywhere from $3,000 to $10,000 depending on the material, tread, number of stairs, handrail, etc. OSHA stairs are generally more cost-effective than IBC stairs, saving companies up to 30% because OSHA requires fewer treads, a shorter horizontal run, and less extra handrail. 


IBC stairs are typically larger and take up more space, requiring extra handrails and deeper tread. For a standard staircase, installation adds approximately $1,000.
