We are proud to inform you that we had issued a new ducting range catalogue. We have carried out quite a few upgrades and improvements of our existing models of manhole covers and gratings, which are specially marked with »MODEL 2016«. We have also added our complementary products programme of concrete rings. Batch production of a few models of our new type is already underway, while some are still undergoing final testing. We plan to start selling all new models at the beginning of May. More at: New catalogue 2016.
