We are one of the largest manufacturers of underground fiberglass storage tanks in the world.
Now owned by Shawcor Ltd., Xerxes is a leading innovator in composite tank engineering, with more than 40 years of direct industry experience. When ZCL Composites Inc. acquired Xerxes Corporation in 2007, it brought together North America’s two leading fiberglass tank brands: ZCL (founded in 1987) and Xerxes (founded in 1979).
Our track record of 200,000+ installations stands as proof of the reliability and excellence of our products. Xerxes tanks are structurally strong and made of 100% premium resin and glass (no fillers), making them corrosion-resistant, both inside and out. These are just a few of the reasons engineers and project specifiers select our tanks as the ideal storage solution for their Fuel and Water applications.
We offer both underground and aboveground fiberglass tank options – plus a full complement of accessories. Our six UL-listed or ULC-listed manufacturing facilities across North America ensure that no matter where an installation is, we are able to provide the right tank in a timely manner. Our dedication to delivering peace of mind to our customers through corrosion-resistant solutions that preserve and protect the environment means that our tanks are also the right environmental choice.
