This 600 × 600 mm drop‑in, single‑seal B125 manhole cover and frame is expertly cast from GGG500/7 ductile iron per ISO 1083 for outstanding tensile strength and impact resistance. Rated to Class B125, it reliably withstands a 125 kN (12.5 tonne) test load in pedestrian and light‑traffic environments. Fully compliant with BS EN 124‑2:2015 standards, it ensures both safety and regulatory adherence. The single‑seal labyrinth prevents water ingress and odour escape, maintaining site hygiene and minimizing upkeep. Its 600 × 600 mm clear opening provides unhindered utility access, while the drop‑in design enables rapid removal and replacement for efficient servicing. Independent BSI Kitemark certification further guarantees consistent manufacturing quality and traceability.
Product Overview
The square, drop‑in cover and frame feature precision‑machined seating for a flush, slip‑resistant surface that virtually eliminates trip hazards on walkways and light‑traffic zones. Outward frame dimensions of 705 × 705 mm with a 75 mm depth ensure stable seating within the surround and robust load transfer under traffic. Constructed from GGG500/7 ductile iron, this assembly delivers exceptional durability against mechanical stress and environmental corrosion. A standard 30 µm bitumen coating provides initial corrosion resistance, with an optional epoxy topcoat available for more aggressive or coastal installations.
