Who we are

Our experience, accumulated over the past forty years, during which we have seen the development of aluminium both in Spain and in the rest of Europe, has enabled us to create a dynamic company capable of offering outstanding solutions to customers in this sector.

Quality is our highest priority. For us, this does not only mean the quality of our products, but also the quality of the service we provide to our customers.

We are very demanding in selecting our products and suppliers, and we can confidently say that in our warehouse you will find nothing but the most sophisticated products produced by the world's leading manufacturers.

In our catalogue, you will find products which comply with the highest standards, all of which are produced by the world's leading manufacturers. We have a wide range of aluminium semi-products, as well as an impressive selection of sizes and alloys that are not usually found on the market. We also supply copper alloys.

We have modern, organised warehouses in Vitoria, Barcelona and Madrid, which boast a combined surface area of over 13,000 m2, as well as extensive stock and modern storage systems.

The dynamics of our company allows us to evolve very quickly and develop new products based on the latest technology.

Analysing your needs is our challenge, and finding a solution, our duty. This is why we are always happy to hear from you.
