Manhole covers for heavy volume traffic - Class D400
Heavy or intense traffic is defined as a high number of vehicles, authorised speeds on major urban roads and consistently heavy vehicular traffic at a given time. The manhole covers designed by Saint-Gobain PAM for this type of traffic are strong, durable and resistant thanks to the excellent mechanical properties of ductile cast iron.
