Crossover Stair Features
Because our metal crossover stairs are modular, they can be reused or reconfigured as your needs change. Our professional team of engineers will design a stair configuration layout that’s just for you. Our crossover stairs and the entire line of APEX products will not warp, rot, or rust, meaning that they are low maintenance and will last much longer than wood or steel.
Easy Installation
Our crossover stairs are modular and bolt together.
Code Compliant
Our crossover stairs comply with the Americans with Disabilities Act (ADA) and International Building Code (IBC) and can meet local building codes.
Reconfigurable
Because the system is modular, ramps, stairs and railings can be reused or reconfigured as your needs change.
Modular Design
Modular crossover stairs, platform landings, legs, and handrails bolt together without any on-site welding.
Custom Layouts
Our team of engineers will design a stair configuration layout just for you, and professional engineer stamps are available.
Leveling Legs
Platform legs have 8” of adjustability for uneven ground or ongoing adjustments.
HPD/LEED/ESG
Prefabricated systems are typically made with 6061 and 6063 aluminum alloys containing ≥99% and ≥50% recycled content. Some prefabricated systems can help contribute to several LEED v4.1 credits and other green building rating systems.
100% Aluminum – Long Lasting
The entire line of APEX products will never rust, warp, or rot. All components are low maintenance and will last much longer than wood or steel.
Slip-Resistant Decking
APEX stairs are standard with an aggressive, heavy-duty 3” channel grip strut grating that provides maximum, multi-directional slip resistance. Other decking options are also available.
