Furthermore, we employ lean manufacturing and Six Sigma methodologies to help ensure that our internal manhole covers, sealed manhole covers and gratings and frames are manufactured to the highest possible standards.

In addition, our manhole covers and frames and grating and frames are continuously tested to ensure that they 100% comply with British Standards and successfully pass the required load tests. A certificate of conformance also reassuringly accompanies each consignment that leaves our foundries.
