​

For the foundry, which DTS Group is proud to have in its compound manufacturing metal lining, it all started in 1935 since the first order for cast iron tunnel lining rings for Moscow metro tunnels. Later, the separate iron foundry, casting conveyor, fabrication shop and specialized machining facilities were put into operation to enable a serial production of liner plates required. 

​

Since then, DTS Group completed lining projects for mine shafts, metro tunnels, ventilation shafts and civil tunnels in Ukraine, Russia, Kazakhstan, Poland, Canada and the UK. Those projects included cast iron, cast steel, fabricated rings of different geometry with diameters ranging from 4.00 to 9.00 meters. We, in DTS, are committed to developing complex design and production solutions that will take our customers forward, by paving their way to success.
