Fire Protection
Many County and State fire departments recommend corrugated steel tanks as economical alternatives to bolted or welded water tanks for fire protection storage.  American Tank Company can also provide all fire accessories required for your specific job.  Check with your local Fire Marshall for equipment and approvals.
Installation and Safety
When set on a contained gravel foundation ring installation is easy and affordable.  If anchoring to a concrete foundation is required or requested, American Tank Co. will provide a foundation design and submittal drawings with a California Civil Engineer`s wet stamp for building permits or customer approval.

Irrigation Water Storage                                                                                             
Vineyards, Farms and Ranches throughout the West rely on ATC Corrugated Galvanize Steel Tanks to maximize the efficiency of water well production and to control distribution and pumping cycles.

Placed on Site
A boom truck can set the tank directly on the gravel or concrete pad for easy and trouble free installation. (Some restrictions apply, ask your sales rep for details)

Warranty & Savings
Shop Built Corrugated tanks are backed by a one year manufacturer's warranty.  Tanks are engineered and  manufactured from corrugated hot dipped mill galvanized steel. These tanks are extremely cost effective when compared to bolted or welded steel tanks.

Shop Built Corrugated tanks are typically specified for storage requirements between 2,500 to 15,000 gallon capacities.

Farbertite is a Bituminous Ceramic Emulsion coating.  Applied to the interior of a tank, Farbertite bonds to the metal to form a water tight membrane to inhibit water contact with the steel.  This membrane prevents rust and insures the longest possible tank life.

Corrugated galvanized steel tanks have been manufactured in California for over 100 years.  The normal service life is 25-30 years based on historical observations.  With periodic maintenance, ATC tanks can provide 30 to 50 years of quality service.
