Alfonso Garrido, basing the business in the manufacturing and marketing of farm silos and livestock equipment, founded Symaga in 1985. Symaga divided its portfolio into several business lines: Symaga Silos specialized in designing, manufacturing and marketing galvanized steel silos for storage; Growket, one line focused on livestock, poultry, pig and bovine equipment; and a third one specialized in manufacturing agricultural equipment such as water tanks and vineyard equipment named Agravid. Symaga Group invested huge productive and human resources in order to entitle these divisions as corporative unit.
