Symaga Group was founded in 1985 by Alfonso Garrido to manufacture silos and livestock material. Until 2016 Symaga was divided into several lines, one dedicated to the manufacture and design of galvanized steel metal silos for grain storage; a division for poultry, pig and sheep equipment; and a third specialized in the manufacture of metal tanks for water storage and vineyard equipment.

For livestock equipment the Growket brand was born and for the line of metal tanks and equipment for vineyard Agravid was born. Symaga Group has invested at a productive and human level to provide them with corporate and business entities.
