OUR AREAS OF EXPERTISE

SPECIAL MACHINES

We design, calculate, build, assemble, test and install on site all types of special machines, adapted to the needs and expectations of our clients. CSTI's goal has always been to create compact, robust and easy-to-use designs, guaranteed to be highly durable and sturdy.

SHEET METALWORK

Design, calculation, production, assembly and on-site and in-factory testing: our know-how in the field of stainless-steel sheet metalwork covers all types of productions, from small or medium-sized tooling, to substantial installations such as armoured doors, glove boxes, tanks, heat exchangers or assembly and maintenance equipment.

PIPING

We have developed real know-how in the design, production and installation of piping systems and skids – in steel, stainless-steel and aluminium, and for pressure/nuclear pressure equipment – in order to guarantee facilities for the transfer of fluids (water, sodium, radioactive waste, etc.).

TEST LOOP

Our technical expertise also allows us to offer very high-pressure and high-temperature test loops, specially designed for R&D and guaranteeing reliable and secure testing, measurement and experimentation for the most demanding industrial sectors.
