NOW OFFERING 10 YEAR WARRANTY ON FARM BINS

Sioux Steel offers the longest warranty in the industry on farm bins. Their 10 year warranty comes standard on every farm bin. You get a great quality bin with the longest warranty in the business.

Farm Bin Standard Features

Roofs
The strongest roofs available! Sioux roofs stand up to high winds and northern snow loads, while protecting grain year round keeping it fresh and in condition for years.

32-Degree Roof Slope
The 32-degree slope sheds moisture fast, both inside and outside of the panels

Compression Rings
On bins 21’ to 48’ in diameter, compression rings with locking collars crown the roof for added strength. Every Sioux bin comes with the optimum number of rings.

Roof Ribs and Roof Edge
The roof ribs are deep, double-thick, overlapping and interlocked. The roof edge is rolled 340 degrees to stiffen panel edges and stand up to hard Midwest winds and reduce vibration that may cause failure. Wide ribs allow for easy assembly. Sioux Steel has the strongest farm bin roof in the industry.

4” Corrugation
Corrugation on sheets reduce pressure on the sidewalls and allows grain to flow easily down bin wall with less resistance. Fewer sheets cover a wider area, lowering construction costs.

Fill Caps
Fill caps are designed for one-handed control of the cap. Ground control or flat top-style caps are optional for permanent installation of cross augers or spouting.

Man-Way
You won’t have to wonder if you can make it through the man-way when you’re out in the elements with lots of layers of clothing on. It’s the most user-friendly man-way!

Solid Tieless Walk-In Door
Truly a walk-in door with no cross ties. Clear span opening allows anyone to walk in and out without having to crawl or unbolt any parts.

Hooded Roof Vents
The steel or poly roof vent has a big, wide 15” x 15” inlet area for free air movement.  Lap over design on the steel roof vent prevents leakage of moisture and condensation.

Brock Grain Systems has long had a reputation for providing industry-leading features and bin accessories for farm storage bins. Below are a couple of ways BROCK Farm Bins are DIFFERENT BY DESIGN:

• Giant 40-inch (1016-mm) fill hole features a rigid 24-inch (610-mm) diameter center ring to accommodate most auxiliary equipment.
• Spun steel lid 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.
• Every 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.
• A sturdy tubular handrail placed next to the roof manhole is standard on Brock bins to assist entry and exit through the opening.
• 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. Bins are available with your choice of either narrow-corrugation (2.66-inch / 68-mm wide) or wide-corrugation (4-inch / 102-mm) models.
• Identification codes are stamped on every body sheet providing manufacturing date, part number and steel gauge.
• Sidewalls for all BROCK Farm Grain Bins are assembled using high strength Grade #8.2 bin seal bolts with the JS-500 rust-resistant coating. Brock’s optional rust-proof polypropylene-encapsulated bin assembly bolts provide enhanced corrosion resistance.
• Grain bin foundations are designed to secure the bins against 90 mph (145 kph) winds, even when empty.
• The bin anchor system supplies a strong, load bearing connection to the foundation. This design, combined with the foundation sealant, helps to provide a weather-tight seal.
• Brock's industry-leading five-year warranty program on farm grain bins. See Brock’s full written warranty for complete warranty details.
