Grain Bin Sidewall Roll Formers

Sidewall Lines have been recognized for their robust design, 1mm-5mm thickness capability, a variety of pre- or post-punch / cut options, mechanical or hydraulic press system designs. They are reliable and accurate. Available destacking, stacking, and curving also make them extremely flexible.

Grain Bin Floor Roll Forming Lines

Grain bin floor manufacturing systems are the industry standard. Compact and flexible, they allow inline lancing and corrugating, or corrugating only of pre-perforated steel. Expert tool and fixture design offers maximum control of profile, crowning and twist. The flying, hydraulic, post-cut shear design increases throughput while minimizing scrap. Versatile and reliable Beck Automation controls enable operators to schedule floors in virtually any configuration.

Stiffener Roll Forming Lines

Grain bin manufacturers know that punch accuracy and minimal flare are critical in stiffeners, and so do we. That's why offers a variety of robust, accurate stiffener line solutions to handle product ranging from 1mm to 4mm. Mechanical and hydraulic pre- and post-punch / cut designs mean we can provide a solution to nearly every stiffener manufacturing . 

Grain Bin Roofing Roll Formers

Demand for grain storage space is increasing, and with it the demand for larger grain bins. Grain bin roof lines that produce tapered grain bin roof panels are designed to keep pace with this growing demand. We offer hands free systems capable of producing finished bin sections, including flange bending and vent / access punching, from coil to finished product. Small diameter bins to large, multi-tier bins are well within our system capabilities. Partial systems are available as well, designed modularly to be added onto as capacity demands require.

Ladder Rail and Rung Roll Forming Lines

Designs a full range of grain bin related manufacturing systems, including rafted ladder rung and rail lines for grain bins. These rafted systems allow for production of both ladder rails and rungs in one compact machine footprint. Specialized designed and manufactured tooling produces notched, dimpled, and rolled round-rung profiles, while another set of tools forms the CEE sections for ladder rails. Time- and space-saving rafted roll formers like these are another example of the innovative and flexible solutions we offer for manufacturing grain bin components and accessories.
