Tanks and collecting devices made of plastic are especially suitable for liquids hazardous to water because they often have a more favourable corrosion behaviour than metal tanks and hence are resistant to various storage media (chemicals). In addition, they combine low material weight with high strengths.

The tanks are available in various variants, single-skin, double-skin, horizontal or vertical, with or without secondary containment, with thermoplastic lining or with chemical protection or non-woven layer.
