This section of the blog records our family's sightings of manhole covers and similar items cast by PAM, a major ironworks in France.  The main ironworks is at Pont-à-Mousson that we visited when cruising through the town in 2022.

As well as manhole covers we are collecting other street items manufactured by PAM such as gully grids, utility access covers and tree protectors.  Castings made by PAM are recognisible by having one or more of the following imprinted on them:

  • The words, 'PONT-A-MOUSSON'
  • The company name, 'PAM'
  • The company logo which is a bridge

Most of the contemporary PAM castings are marketed under a specific range and the range name, e.g. 'REXEL' is also stamped on the piece whereas older castings do not have a range name shown.  Castings conform to standards depending upon the usage and the standard can also be found stamped on the article.  The standards, the maximum weight carried and their uses are as follows:

A15 1,500 kg Pedestrians only, e.g. parks and gardens.
B125 12.5 tons Traffic-free pavements
C250 25 tons Car parks, gullies, roadsides, pavements that may be driven or parked on
D400 40 tons Roads
E600 60 tons Major roads including motorways
F900 90 tons Heavy traffic, e.g. airport runways
