History/About Us

History of the company

We are a leading company in the sector, specialising in the transformation and marketing of metal products.

The origins of the company date back to 1941, when, under the name Serrería Navarra S.L., in Olite (Navarra), we began to offer our services to the construction sector. In 1951, our facilities were moved to Tudela, where our headquarters are currently located, and where we have three work centres covering a surface area of more than 25,000 m2. In these centres, constant investment, both in infrastructures and in production means, has enabled us to respond more efficiently and competitively to our customers, extending and expanding our scope of action inside and outside the peninsula, with a global presence in more than 12 countries.

Nowadays, we meet the demand of practically all industrial sectors, thanks to new activities that have been incorporated over time, such as the Iron Warehouse or the Iron and steel workshopWe have also set up newly created divisions, both in the field of business development and in the field of marketing, which have been key aspects in the evolution of the company to the present day. We have also set up newly created divisions, both of Hardware and Industrial Supplies as Upmoviomdivision, a division specialising in Storage SystemsWe adapt to the evolution and needs demanded by our clients.
