About CertainTeed and the PAM Product Line
CertainTeed PAM is the premier provider of technically advanced municipal castings — primarily manhole covers and gratings — operating in the United States today.

Though relatively new to the North American market, the PAM product line is well-established as the European leader in the design and sale of manhole covers and gratings, with over 6 million units in the ground. Our products are sold around the world — and now North American municipalities and utility companies can enjoy the ergonomic and functional benefits of PAM manhole covers and gratings.

PAM manhole covers and gratings are designed with a total focus on the needs of the end-user. The foundation of our innovation is ductile iron, an engineered material that offers significant performance advantages over traditional cast, or grey, iron, including:

  • Greater strength-to-weight ratio
  • Excellent impact resistance and durability
  • Enhanced design ability

CertainTeed's aim is to be the technical leader in municipal castings in North America. And with innovative products like our PAMREX manhole cover, which has already been selected as the sole specification in a number of large metropolitan areas, we're well on the way to achieving that goal.

CertainTeed Corporation is a subsidiary of Saint-Gobain, one of the top 100 industrial companies in the world and a major force in building materials, flat glass, glass containers, insulation, reinforcements, abrasives, ceramics and plastics, and pipes and accessories -- including municipal castings.
