Thomas Dudley provides customers with the reassurance of knowing that our manhole covers and frames and drain covers comply fully with the requirements of BSEN 124:1994 and Highways Authority HA 104/09 Standard.

However, many castings actually break when subjected to loads that are way below those specified by British Standards.

In contrast, our castings are designed and engineered to deliver assured performance. They are also tested to BS standards in our testing facility located within our on-site Quality Suite.

We are so committed to quality that we’ll even test your existing manhole covers and frames and drain covers free of charge, then test ours so that you can compare the quality. Simply complete and submit the form below and we’ll contact you to arrange testing.
