Non-conductive
FRP Cage Ladders
Fixed vertical access ladders pultruded from glass-reinforced profiles — electrically non-conductive and non-magnetic, which is exactly why substation, switchroom and electrolysis plant operators specify them over steel. Cages, rest platforms and walkway tie-ins come from the same system.
- Stringers 80 × 25 mm pultruded C-profile; 40 mm round rungs
- Safety cage from 2.2 m above grade, per EN ISO 14122 or OSHA 1910.28 geometry
- Rest platforms every 6 m or 9 m per standard
- Wall-mounted, side-mounted or free-standing with support frame
- Ladder-to-walkway safety gates matched to the handrail system
