Offering A Variety of Sizes & Features

Brock offers a full line of Commercial Hopper Silos for temporary wet or dry grain holding, overhead unloading or long-term storage. These BROCK® Silos offer users a variety of sizes, features and capacities to meet grain holding needs. Brock's largest 11-meter (36-foot) diameter hopper silo holds over 1,900 cubic meters (58,000 bushels) of grain.

Sturdy Steel Structure

For greater strength and reliability, Brock's specially-engineered support beam encircles the silo at the top of the hopper, evenly distributing the weight of both silo and hopper to the strong leg support structure. The sturdy support structures on some models have a corrosion resistant galvanized finish while other models feature high-grade, enamel-painted steel. Both provide longevity and low maintenance.

Other Unique Brock Features:

  • More models and choices – hopper-bottom holding silos from 4.6 to 11 meters (15 to 36 feet) in diameter.
