Our history


Bigas Alsina was born in Girona, in a small boilermaking workshop located in Carrer Figuerola, in 1949. Francisco Bigas and Lluís Alsina joined forces to create a business dedicated to the manufacture of boilers and pressure vessels. They began by assembling iron heaters with a coal boiler, but little by little the company specialised, moving into the industrial and meat sectors.


The business grew, especially with the meat sector companies in the surrounding area. This meant developing all kinds of machinery adapted to the processing systems of each producer and learning to respond quickly to the changes that this industry often has to face. From then on, Bigas Alsina has distinguished itself by manufacturing machinery according to the specific needs of each customer.

The evolution of the company

With the sons of the founders, Francesc and Frederic Bigas and Josep Alsina, became a part of the business, the company experienced a strong impulse and moved to the current facilities located in the northern part of the city. With the opening of the new factory in 1969, Bigas Alsina became a brand. The new production area, consisting of an iron boiler workshop and a machining centre, enabled the first batch-cookers to be manufactured and the production of vertical biomass steam boilers to be increased, which became a great success in the wake of the oil crisis of the 1970s.


The incorporation of the third generation of the family into the business, with Enric and Frederic Bigas as operational managers and Josep Alsina as workshop manager, meant that in the 1980s the rendering division, dedicated to the design and manufacture of by-product processing plants, was consolidated and began to be installed all over the world. At that time, the company already had a building dedicated to electrical work.


The growth of the company led to the expansion of the industrial maintenance service, boiler maintenance and maintenance of fluid installations throughout the Girona area, which allowed us to significantly expand our client portfolio by entering new sectors such as hotels, health, education and other sectors related to public buildings.


In 1992 Bigas Alsina took another step forward in its growth by incorporating its own stainless steel workshop and a machining workshop into the company’s structure. In 2019, the new technical offices were created, reflecting the company’s avant-garde vision and its innovative spirit open to broadening new horizons.
