Abstract

A high strength industrial storage tank is provided. The tank includes a pair of opposed sidewalls, a pair of opposed end walls, each end wall interconnecting the sidewalls, and a floor connected to the sidewalls and the end walls. Each of the sidewalls and end walls includes a series of alternating vertically extending outer members and vertically extending grooves. Each groove extends toward the interior of the tank and includes a bottom and two sides. Each groove further includes an inner arcuate portion that is arched toward the interior of the tank and has a substantially constant radius of from about 3.0 to about 4.5 inches. The structure of the sidewalls makes it relatively easy to clean the tank and apply and maintain paint and other protective coatings on the surfaces of the tank. The tank can optionally include structure that makes it suitable for storing liquids and other fluids and/or structure that makes it compatible with roll-off transport trucks.
