Steel Stairs Fit into A Variety of Environments!

Panel Built's prefabricated steel stair systems can be found everywhere from hospitals to warehouses to military bases.  That is because each of our stair systems is uniquely designed to meet the customer's requirements as far as layout and aesthetic.   

When installed into manufacturing facilities, our steel stairs can be economically designed to meet your company's budget (while fitting into your facility's codes and compliances). At the same time, we often fabricate stair systems that aim for a sleeker, more contemporary look, used in an office or even retail locations.

Exterior Steel Stair Designs Also Available!

With Panel Built's stair assemblies utilizing steel construction, our systems are able to withstand the toughest environments and meet the most strict standards.  Our stair systems can be used for both interior and exterior applications.  For our exterior steel stairs (like access stair systems), Panel Built uses either galvanized dipped steel or exterior rated powder coat to protect the stair systems. 

Steel Stairs Meet OSHA and/or IBC Codes

With our steel stair systems being installed into so many different environments, Panel Built has designed them to meet and/or exceed a number of stair regulations.  However, if you have even more strict stair codes, we can customize the system's slope, risers, and railing to satisfy those standards. 

Differences Between IBC and OSHA stair codes


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.


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.
