Product Details
INNOVATIVE ROOF SYSTEMDEEP RAFTERS PROVIDE A STRONG BACKBONE
Corrugated 3½' high ribs with four stair steps on both sides provide outstanding strength. Panels are roll formed for a precision fit. This process assures the adjacent roof ribs match perfectly for ultimate strength.
RIGIDIZED ROOF PANELS
Roof panels attach to the roof structure with special brackets to connect to the top of the roof rib minimizing penetrations through the valley and creating a more weather-tight roof.
The nearly 11' diameter roof deck provides ample space for mounting overhead equipement. Behlen engineers will work with customers to provide custom built supports to fit nearly any requirement.
Wall System
UNIQUELY DESIGNED WALL SYSTEMS
The Behlen flat-sided (trapezoidal) corrugation uses a flat surface for bolt-to-wall panel connection. This flat-sided configuration provides for maximum strength while giving a superior weather seal where the bolt, washer, and wall sheet connect. The Grade 8.2 bolts are formed with a pocket in the head which helps to hold the washer in place and channel moisture away, providing another level of protection for the grain inside. Behlen bin bolts are coated with JS1000™ extreme life plating, providing superior corrosion protection. The distinctive Behlen “built-in” wind bands, offered as a standard design feature with inside stiffened bins only, provide greater strength and rigidity to resist the forces exerted by side draw and wind loads. These precision, roll-formed 1” ribs at each horizontal seam eliminate the need for exterior wind pipes, reducing construction time and cost.
SUPERIOR PANEL STRENGTH
The vertical seam lines have an extensive overlap with up to seven rows of bolts. The precision manufactured panels speed assembly resulting in lower erection cost.
EAVE TENSION RING
A full circle ring at the eave stabilizes the roof and walls under all loading conditions. The heavy rings are fabricated with welded end plates to provide unmatched strength at the eave. This design supports the nonuniform loads created by snowdrifts, side draw systems, high winds, and earthquake forces. The ring is double braced between rafters to provide superior strength in both tension and compression. The eave ring and rafters attach directly to the stiffeners for a solid connection.
The Behlen hat-shaped stiffeners provide superior resistance to grain loads. Each stiffener is formed from a single piece of steel up to 5/16” thick. This use of thick, solid steel eliminates the need to laminate stiffener material. Each of the stiffeners supports the next with a load bearing plate to ensure positive load transfer into the concrete foundation. The use of three heavy duty stiffeners per wall sheet gives Behlen bins the ability to be cleaned with a single pass sweeping operation.
