Texas Metal Tanks WT500G Rainwater Tank, 500 gal Tank, Steel, Silver

With almost 90 years of history, the galvanized steel tanks are G-90 grade 20 ga metal made in the USA. We do not import foreign steel. The top is 22 ga. After the tank is constructed, a paint/epoxy lining is applied to the interior of the tank to provide a protective barrier between the water and the metal itself. This product is FDA approved for potable (drinking) water applications and is ANSI/NSF 61 certified. Each tank is tested at the factory to ensure that it is watertight.
