Abstract

A storage bin may include a corrugated outer sidewall, a generally flat inner sidewall, and a first fastener. The corrugated outer sidewall may support a hoop tension provided by a material within the storage bin and may include a series of horizontally extending corrugations forming alternating grooved portions defining alternating circumferentially extending radially inner and outer ridges vertically spaced from one another along a vertical extent of the outer sidewall. The corrugated outer sidewall may define a first aperture. The generally flat inner sidewall may support the hoop tension, abut the radially inner ridges, and define a second aperture. The first fastener may extend through the first and second apertures and may couple the inner and outer sidewalls to one another.
