Types of Steel
When selecting a storage tank to fill the needs of a city or industry, a comprehensive evaluation should be made of all designs available. Members of the Steel Tank Institute/Steel Plate Fabricators Association (STI/SPFA) give important factors, such as potential service and economic considerations, the careful attention they deserve.
Flared Steel Column (Golf Ball and Tee)
The flared steel column design is common and recognizable. One of the most common and most recognizable designs, these tanks can hold approximately 2 million gallons of water. Many such tanks are designed with elaborate exterior colors and graphics representative of the facilities and communities the tanks serve. As the photos here demonstrate, the shapes of the tanks can be just as varied as their surface appearance.
Fluted Steel Column (Hydropillar)
This tank is elevated by a series of steel columns around its perimeter.The multi-column design was common in the past, but has been replaced in recent years with less expensive designs. STI/SPFA’s Century Club honors water tanks that have been in continuous service for 100 years or more. The multi-column, leg type elevated tank design is common among Century Club members, as is the standpipe design.
