Roca Corporación Empresarial, S.A. began business in 1917 as Compañía Roca Radiadores S.A. This company was dedicated exclusively to the manufacture of cast-iron radiators for home heating at its factory in Gavà (Barcelona), but the rapid penetration of new products into the market and a solid determination to expand led the areas of business to be enlarged with the aim of diversifying activities. As a result, in 1925 the first cast-iron boilers were made, and in 1929 the company began to make cast-iron bathtubs. In 1936 Roca entered the sanitary tile sector and in 1954 it began to produce faucets and fittings. A second porcelain tile factory was opened in Alcalá de Henares (Madrid) in 1962.
