About DTS

DTS Equipment Ltd. is a UK-based engineering and project company operating through a network of specialised casting and machining facilities in South Korea. We provide design, production, and supply chain solutions for large-scale industrial projects in sectors such as mining, tunnelling, power generation, oil and gas, marine, and heavy equipment.

​

​Originally founded with manufacturing roots in Ukraine, DTS successfully relocated its production base to South Korea following the outbreak of war in 2022. This strategic move ensured full continuity of service for global clients — while expanding our technical capabilities and output capacity.

​

We are best known for our world-class cast iron lining rings (SGI tubbing) for mine shafts and tunnels — delivering watertight, high-precision linings across Europe, Asia, and North America. In addition, we support demanding casting projects for the wind power, metallurgy, and infrastructure industries, offering large one-piece castings up to 80 tons.
