Our covers are compatible with EN124:2015, ASTM and AS standards.
EN 124:2015 is the European standard for gully tops and manhole tops for vehicular and pedestrian areas. It defines load classes by the minimum test force the complete unit (cover + frame) must withstand.
| Class | Test force (kN) | Typical location (per EN 124:2015) |
|---|---|---|
| A 15 | 15 | Footways, pedestrian areas, car parks |
| B 125 | 125 | Kerbside channels of roads, parking areas for all vehicle types |
| C 250 | 250 | Gully tops in road channels, up to 250 mm from kerb |
| D 400 | 400 | Carriageways of roads, hard shoulders, parking areas for heavy vehicles |
| E 600 | 600 | Docks, aircraft pavements |
| F 900 | 900 | Areas imposing particularly high wheel loads (e.g. aircraft pavements) |
Class letters above follow EN 124:2015. In the NEXUS catalogue the load class column uses the short form A / B / C / D - i.e. classes A 15 to D 400. Our moulded range currently covers classes A to D; E 600 / F 900 units are typically ductile iron territory.
Footway, kerbside, carriageway or industrial hardstanding - the location, not the cover size, decides the class.
Covers closer to the traffic lane sit in a higher class. A cover 250 mm from the kerb and one in the wheel path are different jobs.
Send us the chamber schedule - we flag every position where a composite cover fits and return a loading proposal within 24 hours.
