This 700 × 700 mm B125 manhole cover and frame combines robust ductile‑iron construction with a precision‑engineered, drop‑in labyrinth seal to deliver reliable performance under pedestrian and light‑vehicular loads. Designed to BS EN 124‑2:2015 Group 2 (B125) requirements, it supports a 12.5 tonne (125 kN) test load, resists water and debris ingress, and minimizes maintenance through its durable finish and ergonomic installation features.
Product Overview
-
Design
A square, drop‑in cover‑and‑frame assembly with a single, labyrinth‑style seal ensures a flush, slip‑resistant surface that virtually eliminates rattling and trip hazards. -
Material
Cast from GGG500/7‑grade ductile iron (per ISO 1083), providing an optimal strength‑to‑weight ratio and excellent impact resistance under repeated loading. -
Finish
Standard 30 µm bitumen coating offers initial corrosion protection; optional epoxy or powder‑coat finishes are available for enhanced chemical and salt‑spray resistance.

Quality & Compliance
-
Standards
Engineered and tested to BS EN 124‑2:2015 for pedestrian and light‑traffic covers (Group 2/B125). -
Certification
BSI Kitemark (or equivalent third‑party certification) ensures batch traceability, independent quality audits, and full UK/EU regulatory compliance. -
Material Conformity
ISO 1083 compliance guarantees consistent ductile‑iron properties (tensile strength, elongation, hardness).
Applications & Benefits
-
Versatile Use
Ideal for sidewalks, pedestrian plazas, residential streets, driveways, and light‑vehicular zones. -
Low Maintenance
Sealed, corrosion‑resistant design reduces cleaning cycles and extends service life, lowering total cost of ownership. -
Safety & Serviceability
Flush, slip‑resistant surface and ergonomic lift‑points enable safe, rapid access for inspection and maintenance, with minimal downtime.
