Marmox Manhole Steps

Extreme Corrosion Resistance: Complete encapsulation prevents rust and failure caused by corrosive hydrogen sulfide gases and damp conditions.

Enhanced Operator Safety: Anti-slip tread and lateral containment lips protect maintenance personnel in dark and hazardous chambers.

High Load Capacity: Internal steel reinforcement supports heavy dynamic loads and equipment-laden workers.

Maintenance-Free Life: Long service life with zero requirement for anti-rust coatings or periodic structural replacements.

Flexible Installation: Suitable for pre-cast embedding into concrete walls during casting or post-installation via chemical anchors.

Municipal Sewage & Storm Water Manholes: Permanent access ladder runs inside main and secondary drainage inspection chambers.

Underground Utility Pits: Non-conductive, corrosion-resistant steps for telecom, water, and power distribution vaults.

Water Reservoirs & Treatment Plants: Internal wall steps for potable water tanks, aeration basins, and pump sumps.

Industrial Wastewater Facilities: Access ladders inside industrial effluent pits exposed to aggressive chemicals.

Pre-cast Embedding: Position step tails within the wall formwork prior to pouring concrete for maximum mechanical bond.

Post-Drill & Anchor Installation: For existing concrete walls, drill holes to specification, clean dust thoroughly, and anchor steps using high-strength epoxy resin.

Vertical Spacing Alignment: Maintain uniform vertical spacing between steps (typically 250 mm to 300 mm) in accordance with international safety codes.

Inspection: Verify anchor alignment, horizontal level, and mechanical pull-out resistance before commissioning.
