Prefabricated Stairs | Prefab Stair Systems

Pre-Manufactured, Yet Customizable Stair Systems

All Panel Built prefabricated stair systems, handrails and components are engineered, fabricated and powder coat painted at our plant for a lasting finish and fast delivery. Panel Built prefabricated stairs can be manufactured to your specification allowing for fully-custom stair sizes, heights, layouts, widths, treads, and specialty metal handrail that meets OSHA and/or IBC codes.

Bolt-Together Components For Fast, Easy Installation

Panel Built's bolt-together stair assembly allows for fast, convenient installation on-site.  Your stair components will be fully fabricated off-site, so when your system is delivered, it is ready for immediate assembly .  Panel Built supplies our structures with all the necessary hardware and materials with your delivery.  Further, Panel Built offers full installation services for most projects.  If you need installation with your stairs, let us know, and we will include it in your quote!

Differences Between IBC and OSHA Stair Codes
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 Collapse
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. IBC landings are larger, typically 4’ square.
