Generator Stair Features
Our APEX Generator Access Stairs meet OSHA standards and we also offer an IBC-compliant option. Apex’s modular design combined with our experienced engineers allows us to offer you any configuration that you need. Made from 100% industrial-grade aluminum, our generator access stairs will not rust, warp, or rot.

Easy Installation
Our generator access stairs are modular and bolt together seamlessly.


Code Compliant
Our generator access stairs are prefabricated and comply with OSHA regulations.

Non-Conductive Decking
Our fiber grate decking option is non-conductive, non-sparking, and non-magnetic.

Reconfigurable
Since the system is modular, ramps, stairs, and railings can be reused or reconfigured as your needs change.

Modular Design
Modular generator access 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.

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.

HPD/LEED/ESG
Because our products are modular, repurposable, and contain 32.5% to 75% recycled content, including 50% to 65% pre-consumer and up to 20% post-consumer recycled scrap, they can help contribute to several LEED v4.1 credits and other green building rating systems.

Slip-Resistant Decking
APEX stairs come standard with an aggressive, heavy-duty 3” channel grip strut grating that provides maximum, multi-directional slip resistance. Other decking options are also available.
