Superior - Model 15' To 27' -Unstiffened Hopper Bins

UNSTRUCTURED ROOF

Roof Load: Superior’s roofs can withstand ground snow loads of 40 pounds per square foot and winds up to 90 mph. Unstiffened hopper bins come standard with an 8,000lb peak roof load.

Roof Ribs: 3-1/2-inch-deep rigidized roof ribs are locked to the roof wind ring, so the roof acts as a single, dynamic unit.

Corrugation: The flat portion of the roof panel is corrugated for additional strength and finished with a formed drip edge.

Roof Vents: Pre-punched 20-by-20-inch roof vents are made from a high-molecular-weight polyethylene that is injected with a U.V. inhibitor prior to fabrication. A 1-inch tall ridge surrounding the vent hole prevents moisture from entering the bin.

Continuous Eave Angle: The continuous eave angle spreads the roof load evenly onto the sidewall sheets.

Bird Clips: Push-up bird clips on eave angles minimize parts and labor.

Wind Rings: Individual pipe sections are clamped and fastened to the roof with a locking bracket at every rib. This adds security and durability by eliminating twisting and displacement.

Formed Peak Ring: Superior’s formed peak ring has three breaks instead of one to resist deformation. The roof panel rests on the peak ring and is pressed into a foam closure to seal it against wind-driven snow or rain.

EXTERIOR ACCESS

Roof Ladder Package: A roof ladder is standard on all Superior bins. For additional safety, add an optional roof ladder handrail package.

Remote Opener: (Standard) A ground control remote opener is standard on all hopper bins.

Exterior Ladder: (Optional) An exterior ladder is optional on all hopper bins.

STRENGTH

Stiffeners: Superior stiffeners are roll formed for a consistently perfect fit. Splice connections on three planes provide critical load bearing transfer between stiffener sections.

Grade 50 Steel: Superior bins use Grade 50 steel that has a tensile strength up to 65,000 psi.

G-90 Bright Galvanization: A G-90 bright galvanized steel coating provides enduring protection against the elements.

JS500 Grade 8.2 Bolts: All bins come standard with JS500 grade 8.2 bolts, which are seven times more resistant for exceptional protection compared to standard galvanized bolts.

3/8-inch Bolts: Superior uses 3/8-inch bolts on all hopper bin sidewall sheets, making the bin easier to erect and stronger than the competition.
