Choice of narrow-corrugation

Choice of narrow-corrugation (2.66-inch / 68-mm wide) or wide-corrugation (4-inch / 102-mm) sidewalls providing a greater variety of bin size and height options.

Practical Innovations

Practical innovations such as easy-open access doors that require no tools, unique roof ventilation systems for more total ventilation and no roof cuts and high-strength aeration floors with ample air distribution and easy clean-out.

Tri-Corr bin floor & Parthenon Supports

Brock’s Tri-Corr bin floor and Parthenon Supports offer superior load bearing capacity and provide ample, even aeration throughout the bin.


Brock’s Harvest-Time unloading systems are a “two in one” system – which means you get under-floor tube and flight conveyor combined with a floor sweep – all driven by a single electric motor. The Harvest-Time unloader and power sweep combination can be operated from outside the bin, or the unloader can be used with a center pivot to connect to an existing portable sweep!
