Grupo Riza is a company in the metallurgical sector with more than 75 years of experience in forging, heavy boilermaking and heat treatment, with facilities of more than 20,000m2 in six industrial buildings. Since its beginnings, it has been incorporating different business lines to its structure, which has allowed it to complete a multidisciplinary group looking for the best solution for the customer's needs.
Grupo Riza began its activity in 1947 as a heat treatment company in Zumarraga (Gipuzkoa), and in 1973, after more than twenty years of activity, it moved to its current location in Ezkio-Itsaso (Gipuzkoa). Over time, Grupo Riza consolidated its position in the heat treatment sector with organic growth based on the reliability and quality of its service.
In 1989, it embarked on a new stage of expansion in the forging sector with the acquisition of the company Labekoa Industrial. In 2004 it bought VTN (Vacío y Termoquímica de Navarra), and in 2005 IATT (Industria Alavesa de Tratamientos Térmicos) was formed; the latter two companies are also dedicated to heat treatment. In 2009, it continued its expansion in the forging business with the founding of Mandubia Eólicas S.L., focusing on the market for larger parts and with special emphasis on the wind power sector. Finally, in 2019, the company LFS (Lekunberri Forging and Services) was founded. This company focuses on forging, heat treatment and machining of large parts (unit weight of 20-25 tonnes). To this end, it has the novelty of having the most powerful hydraulic company in Europe, with a capacity of no less than 13,000 tonnes.
Grupo Riza stands out for its exceptional balance between experience and innovation that increases efficiency and offers high levels of reliability.
