JANSA METAL, S.A., was founded in 1982 by Don Josep Juanola Malirach, offering its services of manufacturing beams, customized girders, with special shapes and steel works intended for buildings that need high quality materials as well as metal frames for use in construction, structures with special needs in terms of high strength; buildings with large spaces of light, high altitudes, without columns (sports halls, warehouses, logistics ...) and steel works for public works, shelters for large surface parking, among many other applications.

During its early years, JANSA METAL, S.A., was in Cabrera de Mar, however, the need for better communication and modernization of facilities, and the need for space, motivated, in times of successor of Don Josep Juanola Malirach, and current chief Mr. Joan Josep Juanola Oller , a change of facilities. This lead the company to its present location, having an area of ​​12,000 m² in the Polygon Can Massagué of La Roca del Valles, with sufficient space for maintaining the current level of expansion, without worrying about space for a few years yet.
