Brock Bins


We have been selling Brock grain bins since Butler Manufacturing became a member of the CTB, Inc family in 1997. Even before that, our crew of bin builders accumulated years of experience on Butler bins, so as Brock merged features from Butler, we were well equipped to seamlessly transition to the Brock line. Butler, a pioneer of the grain bin business and started in 1907, was well known for their steadfast dedication to both product improvement and innovation while using the highest quality of materials to construct their grain storage bins. Brock, founded in 1957, incorporated these aspects and more into their existing line and continue to innovate to this day by pushing the boundaries on storage limits and engineering well-built, cost-effective corn and soybean storage solutions.

Harms Grain Equipment is proud to have had Brock play such an integral role in our many years of success.  The Brock bin line offers everything from farm bins to 100+ foot diameter bins that offer the most roof loading in the industry with the new Everest E-series line. These grain bins also have improved stiffener design to create one of the strongest, efficient bin sidewall that helps them become a centerpiece of the farm or grain elevator system. Since Harms Grain Equipment was founded, we have been building bins and have the skills and expertise to deliver profession service for your grain bin erection project. We offer time tested solutions and can provide powerful custom CAD drawings and layouts of your grain system and how it can all fit together.
