Corrugated Steel Sidewalls

• Sidewalls are created from high-quality 20 through 8-gauge galvanized steel with tensile strength up to 70 ksi (483 MPa) for increased load capacities.
• 4.714" (11.97 cm) peak-to-peak corrugation of sidewalls is 3/4" (1.905 cm) wider than those of the closest competition, reducing the chance for material to collect on the inner walls.
• Chief's 42.5" (107.7 cm) sidewalls increase load capacities and require less hardware than the 32" (81.28 cm) sidewall sections of competing bins. 
• The sidewall steel has a G115 (350g/m2) galvanized coating that provides over 28% more corrosion resistance than the G90 (275g/m2) industry standard.
• Experience enhanced strength and durability with our exclusive corrugation design and innovative bolting system. Our hill-and-valley bolting system utilizes large grade-8 bolts, along with conical sealing washers and serrated flange nuts, providing superior reinforcement for our bins. This unique construction empowers our bins to withstand larger vertical load capacities, and taller sidewall heights, and accommodate more down augers compared to most competing bins. Trust our bins to deliver exceptional performance and reliability in handling your grain storage needs.
  

Anchor System Provides a Sturdy Foundation

Robustly securing the stiffeners and sidewalls to the base, Chief's stiffened and unstiffened farm bins offer formidable protection against sideways forces and uplift. Chief presents two variations of the anchor system, tailored to the bin's size.

Stiffened Farm Bins Provide Better Strength

Chief's Stiffened bins showcase distinctive exterior "W" stiffeners, specifically engineered to withstand nearly twice the weight of alternative stiffener designs. These "W" stiffeners are designed to handle vertical loads, granting added durability that permits sidewall heights surpassing 100 feet (30.48 m). Moreover, they enable our bins to effortlessly accommodate overhead catwalks and conveyors.

Plate-to-plate connections ensure effective load transfer along the stiffener column, eliminating the need for intricate shear-loading splicing. The exceptional "W" stiffeners on the bin's exterior also serve to prevent grain accumulation on the interior walls.

High-Quality Roof Systems

Grain bins from Chief Agri have roofs designed to provide additional storage capacity, maximum protection from the elements, and easier loading.

Chief V-Rib Roof

Chief's V-Rib roof design surpasses leading competitors by incorporating over 30% more roof ribs. This results in an exceptionally strong cover for smaller bins that lack a structured roof. The V-Rib roofs for grain bins up to 27'10" (8.5 m) in diameter have a depth of 2.5" (6.35 cm), while bins ranging from 30'11" (9.4 m) to 49'6" (15.1 m) in diameter feature a rib depth of 4" (10.16 cm). These V-Rib roofs are constructed from the same G140 high-quality galvanized steel as our commercial roof.

Roof Fans and Vents

Chief provides a comprehensive range of exhaust products that are among the most extensive in the industry. Each vent is designed for effortless installation and incorporates features to reduce the accumulation of ice and foreign objects. Additionally, the pre-punched roof panels facilitate quick and convenient installation.

Secure Door Access Options

Chief presents a selection of door options including one-ring double-portal frame doors and two-ring walk-thru doors. These door frames are coated with a galvanized finish to ensure exceptional protection against corrosion.

One-Ring Doors

A one-ring frame door measures 26" (0.66m) wide by 38" (0.96m) high. Bins that are stiffened to meet the standard.

Two-Ring Doors

The large "easy walk" door measures 26" (0.66m) wide by 62" (1.57m). A person can move through the door without fear of catching obstructions because there are no brackets or hooks attached to the frame.

Convenient Latch System

The easy latch system on the inside and outside panels allows entry without the use of tools. A lockable outside cover secures the contents and prevents unauthorized access.

Roof Stairs

With Chief bins, access to the bin's middle and peak is safer and more convenient with handrails.

Accessories

We can source and supply a wide range of products to complete your project through our strategic partnerships and vendor relationships.

Grain Unload Systems

You can choose from a full line of Sudenga products for your system. You can choose from Sweep and Unload Augers, Portable Augers, and a variety of other grain-handling accessories.

Commercial Bins

Offering a peak load capacity of 50,000 pounds (22,680 kg) on Chief’s Larger Bins. Chief provides a wide range of standard and optional roofs to meet your specific peak load capacity requirements and handle snow loads in your region. A 50K roof is optional for CB30 and CB34 bins, which can increase peak load capacity to 50,000 pounds (22,680 kilograms).

Peak Loads May Not Need Additional Support

A 50k roof may not require an additional support tower or catwalk if peak loads are low. Most conveyors with a capacity of 60,000 BPH (1,524 MTH) can be supported by 50K roofs with a 6' (1.82m) or 12' (3.65m) peak ring. As a result, there is no need to span a catwalk/truss across the bin roof and install an additional support tower and catwalk.

Promote Faster Fill Times With 50K Roofs

Using a 50K roof with a 12' (3.65m) peak ring will allow you to fill containers faster with larger capacity conveyors.

Grain Entrapment Prevention

There are anchorage points at the bin peak and manhole on all Chief bins, so anyone entering the bin can tie off.

Strong and Long-Lasting

Chief manufactures premium corrugated steel sidewalls with a formidable tensile strength of 70 ksi (483 MPa). These sidewalls are equipped with 5/16- and 7/16-inch grade 8 bolts, accompanied by conical sealing washers and serrated flange nuts.

To ensure long-lasting durability, Chief incorporates specific coating and adheres to stringent standards when designing their bins.

• Roof sheets with a G140 (425 g/m2) galvanized coating. (56% thicker coating compared to G90)
• Sidewall sheets and stiffeners with a G115 (350 g/m2) galvanized coating. (28% thicker coating compared to G90 (275 g/m2)
• Bolts and serrated nuts with a 1000-hour salt spray test coating.

Less Assembly Time

In comparison to competing bins with 32" (81.28 cm) sidewall sections, Chief's 42.4" (107.7 cm) section requires fewer rings, seams, and stiffeners. With our exclusive "W" stiffener, Chief bins offer unsurpassed strength with minimal assembly time.

Offering Wind and Seismic Upgrades

Every bin produced by Chief is meticulously designed according to the specifications outlined in ASCE 7-16. Additionally, these bins can be customized and reinforced to effectively withstand the unique environmental loads characteristic of your particular region, should the need arise.

Get Easy Access to Doors

Chief provides convenient access doors that come in two options: one-ring double-portal frame doors or two-ring walk-thru doors. Both types are equipped with an effortless latch system, allowing for unimpeded entry without the need to remove cross ties, tie rods, or tie bars.

The dimensions of the one-ring door are 26" (0.66 cm) in width and 26" (0.66 cm) in height, while the walk-thru doors measure 26" (0.66 cm) wide and 50" (1.27 m) tall. To ensure exceptional resistance against corrosion, the door frames are subjected to a hot dip galvanization process.

Bobcat Door With Drive-in Option

The door, which offers great convenience, has dimensions of 7'1" (2.164m) in width and 8'8" (2.68m) in height. To ensure exceptional resistance against corrosion, the door undergoes a hot dip galvanization process.

Vents and Roof Exhausters

Chief provides the most comprehensive exhaust line in the industry. Each vent is designed for easy installation and is specifically engineered to minimize the accumulation of ice and foreign materials.

Side Draw Design Boosts Strength and Unload Speeds

Chief offers an innovative side draw system that enables the establishment of efficient load-out stations for various purposes, including truck, rail, or any other specific load-out requirements. These stations can handle capacities of up to 40,000 bushels per hour (1020 MT/H).

The newly introduced side draw system by Chief enhances the structural integrity of the bin wall while effectively channeling the grain from the ceiling to the side draw discharge opening. The inclusion of intake openings also aids in redistributing the grain, discouraging bridging issues.

To cater to different needs, Chief provides three different sizes of the side draw system. The bushel per hour capacity mentioned is based on test results conducted using runs of #2-grade corn.

• 14" Spout - 10,000 BPH (255 MT/H)
• 18" Spout - 20,000 BPH (510 MT/H)
• 24" Spout - 40,000 BPH (1020 MT/H)

Roof Inspection Door Accessible From Eave Platform
