Prefabricated, Yet Custom Designed Metal Stairs

All Panel Built metal stairs, railing, and components are engineered, fabricated and powder coated at our plant for a lasting finish and fast delivery. But, that does not mean you will be receiving a cookie-cutter steel stair system. Each metal stair project is still custom-designed to fit your specific space needs.  That means if you need a specific stair layout with multiple landings, U-turn stairs, or a special Rise/Run, we can accommodate these custom designs. 
And Panel Built's metal, steel stair features do not stop there! Panel Built offers a variety of handrail options to increase the safety of your new metal stair system. Handrail pickets, intermediate horizontal railing, mesh siding, and glass siding are just some of the different options we can accommodate. In addition, stair treads come in diamond plate, bar grating, or even cement-filled pans. And both open and closed risers are available. 

Bolt Together Design = Quick & Easy Metal Stair Installation

With all of the stair fabrication done in our facility, once your new metal stair system is delivered to the project site, all that is left is the assembly. Our systems use the same bolt-together Steel Stairs design that is used in Panel Built's mezzanine systems. This design helps to ensure that your stair is assembled as quickly and easily as possible.  

Both Interior & Exterior Steel Stairs Available

Our standard metal stairs are built to withstand even the harshest industrial environments. However, if your stair system is for an exterior application (like an Access Stair System), 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 steel stairs can be entirely hot-dipped galvanized to give it a weatherproof, zinc coating, allowing for long life outdoors.

Do You Need IBC or OSHA Metal Stairs?
Horizontal Run
Collapse 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
Collapse IBC Stairs typically have a 7” closed riser and an 11” tread.
Stair Width 
Collapse IBC Stairs are minimum 36” wide in most cases.
Railings and Guardrail
Collapse IBC Stairs require rails of 42” high and handrails of 34” high on both sides of the stairwell.
Collapse IBC also requires an intermediate landing on stairwells for stairwells over 12’ high, as well as handrail extensions at the bottom landing.

Collapse 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
Collapse OSHA Stairs typically have an 8” closed riser and an 9” tread.
Stair Width
Collapse 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, although IBC landings are larger, typically 4’ square.
