UIG is the top supplier of welded steel tanks of all capacities, from small applications of a few hundred gallons to the largest industrial tanks measured in millions of barrels.

We offer individual tanks as well as complete packages that include all appropriate peripheral equipment and systems.

Naturally, the metallurgy of your tank and its peripheral equipment will be properly selected for its expected contents.

There are two types of welded steel tanks - shop fabricated and field installed (or "shop-welded" and "field-welded").

Shop fabricated steel tanks are limited to a size of about 16 feet (~5 meters) in diameter. The tanks are constructed and completed in the fabrication shop for later shipment to the job site.

The other type - field installed welded steel tanks - are typically larger than can be shipped to the site in one piece, thus requiring field welding to complete the tank installation. These larger tanks are constructed in sections at the shop. The sections are then shipped to the site and prepared there. The field installation process involves welding the sections together, as well as the addition of all connections and peripherals, plus final painting.

UIG will manage the various environmental concerns and regulations associated with these operations. Our experienced crews will complete the tank and system installation and thoroughly test them before being handed over to your staff.
