Superior Strength & Corrosion Resistance for Long-Lasting Grain Protection

Strong Sidewall body sheets for Brock's On-Farm Grain Bins

We know you want your bins to be strong. That’s why Brock’s strong sidewall body sheets are made with G-90 galvanized steel with a tensile strength of 65 ksi (448 Mpa) to protect your grain and provide maximum strength at all levels.

Brock's Grade 8 bin seal bolts

Sidewalls for all BROCK® On-Farm Grain Bins are assembled using high strength Grade 8 bin seal bolts with the JS1000™ rust-resistant coating. Brock’s optional rust-proof polypropylene-encapsulated bin assembly bolts provide enhanced corrosion resistance.

JS1000 trademark is not owned or licensed by CTB, Inc.

Capable of Sustaining Winds up to 105 MPH (169 KPH)

The bin anchor system is another reason customers trust Brock. It supplies a strong, load bearing connection to the foundation. This design, combined with the foundation sealant, helps to provide a weather-tight seal. Plus, our grain bin foundations lead the industry and are designed to secure the bins against 105 mph (169 km/h) winds.

Safe, Convenient Bin Access Features

LATCH-LOCK® Walk-Through Bin Door
Why struggle to squeeze through a small, tight opening when you could just open a door to walk into your grain bin for inspections? A standard feature on all EVEREST Bins is Brock’s LATCH-LOCK® Walk-Through Bin Door. This two-ring tall galvanized steel door makes entering even the largest grain bins easy:

The one-piece outer door opens wide to latch securely against the side of the bin. The door’s three or four inner panels open in sequence from top to bottom with a simple lift of the patented latches. No tools are required. Meets recommendations for bin entry, rescue and safety standards.

LATCH-LOCK® One-Ring Door
A one-ring (tier) LATCH-LOCK® Door is available on BROCK® flat-bottom grain bins and is standard on Brock’s EVEREST® Hopper-Bottom Holding Bins.

Large Roof Manhole
No more squeezing through tight roof manholes. Every BROCK® roof is supplied with a large manhole that has a people-friendly “obround” shape for easy entry and exit. Its cover has heavy hinges and a strong, rotating latch.

Sturdy Tubular Handrail
Standard on BROCK® bins is a sturdy tubular handrail placed next to the roof manhole to assist entry and exit through the opening.

Large Fill Hole
A giant 39-inch (991-mm) fill hole is just one of the ways Brock puts customers first. It features a rigid 24-inch (610-mm) diameter center ring large enough to accommodate most auxiliary equipment.

Other BROCK® On-Farm Grain Bin Features

Identification Codes
Every body sheet contains a stamped identification code providing manufacturing date, part number and steel gauge.

Spun Steel Lid
The spun steel lid helps keep your grain in top condition for many harvests to come. It is shaped from a single piece of galvanized steel for a tight, life-long fit. The lid opens wide for easy access to the fill hole or latches tightly to make a weather-resistant dome.

* Maximum Capacity (Peaked Storage) for a bin allows for grain to be at the normal (28-degree) angle of repose, starting one inch (25 mm) below the eave. The grain capacities listed are based on ASAE Standard: ASAE S413, with a compaction factor of 6%. Metric tons are based on ASAE Standard D241.4 of 721 kg per cubic meter for corn and 772 kg per cubic meter for wheat. Bins are designed to meet ASCE 7-10 code requirements for 105 mph (169 km/h) wind zones and UBC 97 seismic zone 1. Standard non-stiffened bin roof peak capacity for Brock’s 4-panel roof is up to 10,000 pounds (4,500 kg) depending on bin diameter. Rating is based on ground snow loads of 30 pounds per square foot (146 kg per square meter). In the pursuit of LEADERSHIP THROUGH INNOVATION®, we reserve the right to change specifications without prior notice.

Because you will customize your grain storage system to your unique needs, not all potentially dangerous or harmful situations can be identified by Brock Grain Systems at the time the bin components and accessories are manufactured. Therefore, it is essential that you think safety first and pay close attention to all possible hazards within your storage systems.
