Build-In Step Iron for Manhole Chambers

The Build-In Step Iron for Manhole Chambers is designed to be built into chamber walls during construction, creating a permanent foothold for pedestrian access into inspection chambers, drainage systems and underground utility structures.

Manufactured from galvanised ductile iron, these steps provide a strong and durable access solution with corrosion protection for long service life in below-ground environments. The treaded anti-slip step surface helps improve grip when entering or exiting chambers in damp conditions.

These chamber step irons are commonly specified for new inspection chamber builds, utility chambers, service pits and drainage access structures where safe ladder-style entry points are required. They are intended for pedestrian access use only.

Two sizes are available to suit different wall thicknesses and embedment requirements. The 115mm option is typically used where a shorter tail length is suitable, while the 230mm option allows deeper build-in fixing into thicker chamber walls or masonry construction.

Designed, manufactured and tested to EN13101:2002, these steps provide a recognised specification standard for access chamber components. Always install during chamber construction using suitable spacing, alignment and structural support. These products are not intended for retrofit bolt-on use.
