Our bolt-on tanks arrive at the job site as a complete kit including hardware, structure and accessories, so they are built in 1/3 the time of other tank designs. All bolted tanks are manufactured at the factory, eliminating the need for tanks to be coated on site and ensuring a high-quality finish to fully protect the steel from corrosion. Our bolted steel tanks have a lifespan of up to 30 years, providing lower overall life cycle costs. Our bolt pots consist of replaceable panels so maintenance, relocation, expansion and export have never been easier.
