Do You Need IBC or OSHA Metal Stairs?
Horizontal Run
IBC Stairs have a horizontal run that is approximately 1.5 times the deck height, not including landings or handrail extenders, so a 10’ high mezzanine deck would have an approximate 15’long stairwell.
Risers & Tread
IBC Stairs typically have a 7” closed riser and an 11” tread.
Stair Width 
IBC Stairs are minimum 36” wide in most cases.
Railings and Guardrail
IBC Stairs require rails of 42” high and handrails of 34” high on both sides of the stairwell.
IBC also requires an intermediate landing on stairwells for stairwells over 12’ high, as well as handrail extensions at the bottom landing.
Horizontal Run
With OSHA Stairs the horizontal run and the length of the stairwell, is approximately equal to the height of the deck. For instance if the mezzanine deck height is 10’, the stairwell is 10’ long.
Risers & Tread
OSHA Stairs typically have an 8” closed riser and an 9” tread.
Stair Width
OSHA Stairs are minimum 22”wide.
Railings and Guardrail
OSHA requires railings on open sides of stairwells and a handrail on at least on side, preferably the right side descending at 34” high.
Both OSHA and IBC require landings at the top and bottom of the stairs, although IBC landings are larger, typically 4’ square.

Interior & Exterior Stair Options 

Our standard stair systems are built to withstand harsh industrial environments with our powder coated paint. However, if your stair system is for an exterior application, Panel Built can take care of those too! Our exterior metal stairs utilize an exterior rated powder-coated paint to withstand the rigors of outdoor weather and abuse. Additionally, the Panel Built stairs can be entirely hot-dipped galvanized to give it a weatherproof, zinc coating, allowing for long life outdoors.

Designs For Practically Any Environment

While Panel Built frequently building in harsh manufacturing and military environments, our stair systems can be designed to seamlessly blend into office buildings, convention centers, motels, and more!  In addition to being long, lasting and durable, our systems can be given custom railings, treads, and more to give the design a sleeker, more modern look .  Our custom stair railings not only provide a great aesthetic, but also creates an overall safer stair system (using pickets, additional railing, expanded metal, or plexiglass to create a barrier).
