Why use prefabricated metal stairs in place of a cage ladder?

Modern industrial stairs—like the APEX and ErectaStep aluminum designs—offer a safer, more ergonomic, and code-compliant alternative to outdated cage ladders. These modular aluminum systems provide stable, hands-free access while meeting current OSHA and IBC safety standards, helping facilities reduce liability and improve worker confidence. Top safety advantages include:

  1. OSHA 1910.28 Compliance: Cages no longer qualify as fall protection on new fixed ladders over 24 ft. Ladders installed after Nov. 19, 2018 require a fall arrest or safety system, and all existing caged ladders must be upgraded by 2036.
  2. Prefabricated metal stair systems meet these OSHA rules—no harness or lifeline needed.
  3. Full-Body Protection: Eliminates the entrapment and fall-through hazards common with cage ladders while providing continuous guardrail protection.
  4. Stable, Ergonomic Climbing: Workers ascend in the direction of travel with secure footing—no vertical climbing strain or restrictive harness gear.
  5. Built-In Rest Landings: Reduce fatigue and allow safe pause points for carrying tools or materials.
  6. Faster Emergency Response: Open, unobstructed design enables quick rescue access in the event of a fall or medical emergency.
