Galician Consortium
of Thermal Treatments

Heat treatment of large steels
in vacuum furnace

Multi-sectoral activity

naval sector

(civilian and military)



COGALTRA is a company established in 2020, promoted by Grupo Intaf and Tumbadoiro, with the participation of Mecanizados Moan, Demaq and Ipargama. It has been financed by IGAPE in the framework of the Advanced Manufacturing Centres programme, financed with FEDER funds. It will start its heat treatment activity in 2022, applying the most innovative production technologies on the market.

The project was created to address the shortage of companies that carry out heat treatments on steels, with the dimensions, quality, price and timeframe appropriate to the needs of the promoters and those entities that have shown their interest and in general to the Galician industrial fabric that continuously demands this process.

Intaf activates in Narón its unique steel parts treatment centre in Spain

Alfonso Rueda celebrates a project that will serve “200 companies in Galicia”. The Intaf Group has already started up its centre for the treatment of large steel parts. It is a unique infrastructure in Spain. The main feature of the manufacturing centre is a system of furnaces in which an investment of more than 2.6 million euros has been made (80% financed by the Xunta de Galicia through the Igape).
