1220x675x100 mm Highways D400 Loading Ductile Iron Cover & Frame Double Triangle
Our manhole covers (document number 1) are tested and kitemarked in compliance with BS plate number 1, and are also fully compliant with plate numbers 2, 3/09, and 4. In addition to these standards, we conduct additional tests, such as randomly placed load tests, which are not outlined in any standard but are more aligned with real-life scenarios.
