steel fuel tanks

Cistas industrial, manufactures fuel storage tanks to be installed aboveground and underground to storage from 2.000 to 100.000 litres. The outer liner type will depend on the location of the tank, being the manufacturing process the same for both versions. In Cistas industrial our tanks may be manufactured with one or more compartments, and may be equipped with access ladder to the manhole and bar grating. A remarkable feature of our manufacturing process is that all our tanks are welded with a submerged arc.

Our commitment to provide the necessary resources to ensure the compliance with the quality standards in our services and products, has allowed us to obtain in the year 2007 the Quality Certificate ISO 9000, awarded by the Spanish Association for Standardization and Certification (AENOR).

All the fuel tanks are manufactured by Cistas Industrial upon request, which allows us to adapt the production to our customer needs.
