What are BUTTERFLY RIBS^TM

The unique Butterfly Ribs^TM are unparalleled in ability to resist vertical and horizontal ground pressure. The series of short, flat, triangular surfaces keep the direction of forces in line with each rib, thus substantially increasing stiffness compared with curved rib tanks. In curved rib tanks, approximately 50% of the curved wall surface area is capable of resisting vertical loads, whereas 100% of the wall surface area of Butterfly Ribs^TM contributes to the load bearing capacity of the tank.
