Shawcor extends its composite technologies offering with the acquisition of ZCL I Xerxes.

In April 2019, Shawcor completed the acquisition of ZCL Composites Inc., now known as Xerxes by Shawcor. Xerxes by Shawcor is North America’s largest manufacturer of environmentally friendly fiberglass underground storage tanks for the fuel, water and wastewater and oil and gas markets. ZCL is an innovator in composite tank engineering, with nearly 40 years of direct industry experience.

When ZCL 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). Xerxes by Shawcor's product offering includes underground composite tanks and a full complement of accessories. There are six UL-listed or ULC-listed manufacturing facilities across North America ensure that it is able to supply its tanks throughout North America in a timely manner. Our tanks are made of 100% premium resin and glass (no fillers), making them corrosion-resistant, both inside and out. To date, we have installed more than 200,000 composite tanks.
