  3. The Company
We have positioned ourselves as one of the most dynamic and innovative companies in the construction of public and private buildings.

Metalúrgicas Jansa was founded in 1982, establishing itself as Jansa Metal S.A. in 1987, a company founded by Josep Juanola Malirach thanks to a strong commitment to the foreign sector, it now represents more than 90% of our turnover. Through constant work, and by studying new solutions and processes that regularly allow the incorporation of technical and organisational innovations, we have managed to reduce the manufacturing and assembly processes, providing greater flexibility at all levels.

All this progress entails an improvement in product quality and customer service, with construction supplies that guarantee satisfaction and perfect fulfilment of their purpose. We stand out for our ability to tackle new innovative projects, highlighting the precision of all our products and our capacity and versatility of custom solutions.


We are highly qualified professionally, in order to achieve the common objective of offering the most suitable solutions for each type of construction, certified in accordance with the EN1090 standard in Execution Class 3 (CE marking).

We also have the ISO 9001 quality certification, offering a particularly necessary guarantee in metal construction for public use, both buildings and infrastructure of all types in Spain, France and countries in the north of South America. We implement all the building work in these countries, or very often the supply of "ready to build" customized metal beams and structures for workshops and construction companies, as well as for engineering companies, architectural studios and even private customers.


With a good approach to work, the know-how and high level of organisation that characterises us allows us to analyse the different economic proposals and possible structural solutions, in order to adjust the resources to customer needs and possibilities.

We guarantee the most appropriate costs for the size and possibilities of each project and we reduce construction time by a third.


To complement our products, our own engineering department allows us to offer a comprehensive service.

This comprehensive service can range from a technical and economic analysis in the preliminary project phase to the full completion of the project with turnkey delivery, including calculations, manufacturing design, quality control systems, safety, assembly, coordination and maintenance.

Always providing every facility for the customer, and ensuring the highest levels of efficiency.
