a solid reason

The „Solid Reason“ initiative was launched by the members of the European Association for Ductile Iron Pipe Systems (EADIPS)/Fachgemeinschaft Guss-Rohrsysteme (FGR) e. V. All members are committed to the use of robust, recyclable and mainly regionally produced ductile iron pipe systems in Europe. These systems consist of pipes, fittings and valves and are the basis for a solid reason on which we can all build.
