FRP Crossover Stairs Are Built To Last

While steel stair systems rust and weaken, FRP stairs and platforms stand up to the harshest environments. Corrosion-resistant and chemical-resistant FRP crossover stairs won’t rust or rot. The surfaces of FRP grating stairs provide superior slip resistance even in oily or wet conditions, helping to reduce the risk of worker slips and falls. All pre-engineered FRP crossover stairs from OSCO meet OSHA and IBC requirements, including OSHA Crossover Stair Riser Height regulations.

Easy To Install

FRP stairs are lightweight, so they’re easy to move around the installation site without the need for special lifting equipment. You can build crossover stair platforms, permanent roof crossover stairs, FRP stairs, walkways and more without the need to hire welders or rent specialized tools — FRP crossover stairs install easily with everyday tools.


Because pre-engineered industrial stairs are available in a range of heights to meet most standard clearances, you don’t need to pay extra or wait longer for a custom solution. We can help you get the fiberglass stairs you need for safe access over retaining walls, pipes, tanks, conveyors and nearly any obstruction.  

OSCO offers a complete selection of safety solutions, so you can get everything you need for any crossover stair configuration from a single source. Add industrial handrails for stairs, fiberglass stair treads, roof crossover stairs, industrial stairs and platforms — the list goes on and on. When it comes to FRP crossover stairs for any project, OSCO Safety has you covered.
