All the features of Chief's largest commercial bins in sizes ideal for the farm!

Chief stiffened bins from Chief Agri/Industrial have long been used as an integral component of commercial grain management systems. Now, they are available in sizes ideal for use on farms, offering all the features that have created the Chief reputation for superior strength, durability and ease of installation.

Available in diameters of 15'6" (4.7m) to 49'6" (15.1m) and overall heights of 19' 2" (5.84m) to 82'3" (25.07m), there's a Chief stiffened or unstiffened bin to fit the needs of any farm operation.

Chief Sidewall Packages are Built to Last

Corrugated Steel Sidewalls

  • Sidewalls are created from high quality 20 through 8 gauge galvanized steel with tensile strength up to 70 ksi (448 mpa).
  • 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 "W" Stiffeners Lead the Competition in Strength

Designed to provide supplemental strength to the bin walls, the exterior "W" configured stiffeners can bear almost twice the weight as the closest competing stiffeners.

A plate to plate connecting system fuses the stiffener lengths and positively transfers the weight bearing load down the stiffener column.

Anchor System Provides a Solid Base

By firmly anchoring the stiffeners and sidewalls solidly to the foundation, Chief stiffened and unstiffened farm bins provide strong resistance to lateral movement and uplift.

Standard G115 Galvanized Coating Offers Superior Corrosion Resistance

G115 (350 g/m2) galvanized coating is used on all roof panels, sidewall sheets, and stiffeners, providing over 25% more protection than the G90 (275 g/m2) industry standard.

JS 500 coating is used on all hardware, providing superior protection when compared to standard zinc coating.

Zinc coated 1/2" (1.27 cm) and 7/16" (1.11) cm) grade 8 bolts with serrated flange nuts are used to provide maximum strength.

Superior Roof Design

Chief V-Rib Roof

Chief's enhanced roof structure features one of the strongest designs in the industry. All grain bins through 37' 1" (11.30m) diameter eave incorporate a 2-1/2" (6.35cm) rib depth. Bins from 42' 0" (12.80m) diameter through 49' 6" (15.08m) diameter have a full 4" (10.16cm) rib depth.

The Chief roof system incorporates over 30% more roof ribs than leading competitors for a stronger roof.

Fill hole diameters are now wider for easier grain filling. The peak roof opening for bins up through 37' (11.27m) diameter is a generous 40" (101.6cm). The opening for bins with a 39' (11.88m) to 50' (15.24m) diameter is a whopping 5' (1.52m)!

Convenient Door Access Options

Standard Easy Access Doors

Chief bins have a two-piece portal frame door with an easy latch system to provide unobstructed entry without requiring the removal of cross ties, tie rods or tie bars.

The door frames are hot dip galvanized for superior corrosion resistance.

Optional Convenient Walk-Through Doors

The large 26" x 62" (66cm x 157cm) obstruction free opening provides easy entry into the silo without fear of catching on brackets or hooks.

Located on the inside and outside door panels, the easy latch system allows entry without the need for any tools.

A lockable outside cover secures the contents and protects against unauthorized entry.
