Mild Steel Vertical Storage Tanks

Vertical storage tanks are fabricated of A36 low carbon mild steel. We always use this grade of steel while some competitors use cheaper grades. Tanks are available in either conical-bottom (CB) or flat-bottom (FB) and are welded internally and externally for maximum resistance to corrosion and weather.

Precision Tank can arrange delivery of your vertical storage tanks upon request. Precision Tank’s unique delivery trailer is capable of erecting the tanks on-location at your job site.
