More models and choices – from 15- to 54-foot (4.6- to 11-m) diameter bins with a maximum storage capacity of nearly 66,000 bushels (2,200 m³).
Strength-providing roof design that offers the highest farm bin peak load capacities available – up to 8,000 pounds (3,600 kg) with a ground snow load rating of 30 pounds per square foot (146 kg per m²).
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 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.

Brock offers a variety of stiffened flat-bottom and hopper-bottom storage bins including the company's line of EVEREST® E-Series Grain Bins and M-SERIES™ high-capacity storage bins.

Brock’s sidewall stiffeners are among the strongest and the most  efficient available to help bins manage the stress and strain of  weather, stored grain, temperature cables and roof-mounted  equipment.

Efficient vertical seam patterns provide improved strength for body sheet connections in both narrowand
wide-corrugation bin models.

Thicker body sheets (up to 5 gauge) resulting in fewer laminated sidewall panels and more efficient use of optimal sidewall thicknesses at all levels of the bin. Standardized 3/8-inch (9.525-mm) diameter bolts on narrow-corrugation sidewall connections provide more efficient connections and fewer hardware sizes in assembly.

JS-1000™ bolt coating contributes improved bolt life expectancy and corrosion protection.

Brock’s unique FULL SWEEP® Bin Anchoring System (patent pending) allows for the safe operation of single-pass sweeps in all Brock Grain Storage Bins: 

Standard feature on all bins 72 feet (22 m) in diameter and larger.
Safely handles normal bin stresses generated during single-pass sweep operation.
Saves time, reduces labor and eliminates the need for bin entry during the sweep process.
Firmly reinforces the bottom-tier sidewall body sheet to anchor the bin and to prevent moisture penetration.

The company «Brock» produces containers with conical bottoms of different sizes, packaging and containers that meet the requirements of any customer.

Brock grain storages are used worldwide thanks to application of practical innovations such as: wavy walls, easy open safe door of service, systems of wall and roof ventilation and ventilation of floor, providing a stable ventilation throughout the space storage.
