A Market Leader in Diameter, Roof Strength and Storage Capacity

Brock’s M-Series™ Commercial Grain Storage Bins feature single bin capacities of over a million bushels and are available in two diameters.

  • 156-foot (47.5-m) diameter M-Series™ Bin models have a storage range from 995,000 to 1.34 million bushels (25,278 to 34,000 metric tons).
  • 132-foot (40.2-m) diameter bin models offer single bin capacities ranging from 688,000 to 1.18 million bushels (17,476 to 29,966 metric tons).

Unique Bin Features Include:

Free-Span Roof Structure
  • Roof peak loads up to 50,000 lbs. (22,700-kg) and 50 lbs. per square foot (244 kilograms per square meter) ground snow loads without center support towers.
  • Temperature cable hangers (shown at right) are built into the rafter system.
  • Special rafter and purlin connections unite the roof structure to more fully develop roof strength to resist bending and to more efficiently handle unbalanced snow loads.

 

SMOOTHCORR® Sidewall System (patent pending)

  • Brock's unique combination of corrugated and smooth sidewall panels offers excellent wind resistance.
  • The inner sidewall features Brock's exclusive smooth-wall surface that allows grain to more easily flow down and out of the bin, reducing load stresses on the bin’s sidewall, stiffeners and footer.
  • Air trapped in the corrugations between the two body sheets contributes insulation value to the sidewall which helps preserve grain quality.


Single-Pass Sweep Operation

  • Brock’s FULL-SWEEP® Bin Anchor System is a standard feature to provide the firm footing required for single-pass sweep operation.
  • Brock MODEL ABC™ Bin Sweep offers both wheel and crawler track drive options.
  • Sweep capacities of up to 18,000 bushels (460 metric tons) per hour.

 

Auxiliary Systems

  • Complete temperature cable packages.
  • Aeration systems up to 1/7 cfm per bushel air flow.
