Heavy Duty Covers and Frames

Our range of heavy duty manhole covers and frames are typically suitable for applications up to load class D400 and used in situations where regular or heavy vehicular traffic occurs.

Heavy duty inspection chamber covers and frames are available in a variety of styles and loads and are typically manufactured from ductile iron. Cast iron and ductile iron covers and frames load ratings include B125, C250, D400, F900.

Due to the vast array of heavy duty covers and frames available, we don't stock them all, however these are all typically available on a 5-day delivery service. 

If you cannot find the size or style of cover that you need, please call our Sales Team on 0800 999 7576.
