Whats the difference between a riveted corrugated steel tank and a bolted flat steel tank?
A. Aside from inherent structural and aesthetic differences, the functional differences are primarily in capacity. Riveted corrugated steel tanks are available in sizes up to 144,000 gallon capacity. Bolted steel tank sizes range up to 2,000,000 gallons in capacity. Generally, corrugated tanks are more economical and have a “hand-crafted” aesthetic appeal. Bolted tanks have the benefit of National Standard recognition, including AWWA and Factory Mutual Insurance approval for fire protection systems. They have an “industrial” look but are more “quaint” in aesthetic comparison to welded steel reservoirs.
