We design and manufacture all our products

At our production centre in Padrón, with over 50,000 m2, we design and manufacture all our products, including:


Hardware and accessories.

Polyamide and PVC insulating profiles.

EPDM sealing gaskets and all types of thermoplastics.

We lacquer all our products.


We have an in-house die-sinking and machinery department.


How we became a global supplier for systems companies

In 2002 we began to design and manufacture hardware for aluminium systems and, later, for PVC systems. At present, we have over 15,000 items in stock.


But we didn’t stop there, in 2007 we opened our polyamide insulating profiles manufacturing plant, adding PVC in 2011.

We are one of the very few ATG-certified manufacturers offering tubular profiles with calibrated interior cavities.

By bringing together these three product lines, we became the first company able to offer services as a comprehensive supplier for any systems company.


Finally, in 2013 we launched our die-sinking and machinery line, enabling us to design and manufacture our own products and offer shorter delivery times.

7. Alualpha


Founded in 1985, Alualpha was born as part of a pioneer company in the manufacture of aluminum windows founded in the 1960s. Due to its dynamism and knowledge of the sector, it quickly became a national leader in this area.


In order to be able to respond to the emerging needs in the specific hardware sector for aluminum frames, the company started manufacturing these hardware as a complement to aluminum frames.


However, in order to be able to respond effectively to market needs, investments were made, both in equipment and in new facilities at Terrugem.


Due to its technical knowledge, determination, creativity and innovation, Alualpha has autonomized itself from this activity.


In 2011 Alualpha renewed its corporate and visual image, creating a new logo, in order to position itself as a global company with its customers and stakeholders.
