Brock grain bins have a world-wide reputation for providing reliable on-farm storage . That's because Brock bins provide dependable, secure storage season after season. Backed by years of design engineering experience and resourceful manufacturing. Brock has led the way with practical innovations such as sidewalls with 4-in wide corrugations for added strength, easy open access doors that require no tools, and 44 inch wide sidewall sheets with result in fewer seams and faster construction. We offer 2.6 inch to 4 inch sidewall bins.

No matter how sophisticated your grain system becomes in the future, the core of that system will always be in the bin. Selecting the right size bin with the capacity you need is easy with the large selection of diameters and eave heights available from Brock. With a complete line of flat-bottom storage bins as well as hopper-bottom holding bins for both farm and commercial markets, Brock now offers single bin capacities ranging from a modest 1,000 bushels to the world's largest bin with 680,000 bushels.

Whether your on-farm storage consists of a couple of bins with an auger or a whole row of bins with an integrated loading and unloading system, Brock Bins are the right choice for the job. Grain bin foundations are designed to secure the bins against 90mph winds, even when empty. Special rolled flanges on the bottom wall sheets provide maximum load bearing on the foundation. This original design also acts as a watershed, and when combined with the foundation sealant, provides a weather-tight seal. These are just a couple of ways our bins are better equipped to provide the security of long-term storage. Call Benchmark today.
