If you need extra support to a step iron, the integrated ladder is for you. We’ve reinforced these polypropylene encapsulated rung with high tensile steel. An additional polypropylene side rail provides extra support. The system is designed to be factory installed into precast concrete chambers by the concrete manufacturer. Once on site, the vertical stringer, supplied in coils, is fed through eyelets on the rungs to form handrails on each side. This can be extended beyond the rungs to just below surface level using optionally available stainless steel brackets for support.
