Farm BinsChief bins from Chief Agri have long been used as an integral component of commercial grain management systems. Now, they are available in sizes ideal for use on a small farm, utilizing all the features that have created Chief's reputation for superior strength, durability and ease of installation.

Available in diameters of 15'6" (4.72m) to 49'6" (15.09m) 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.  Your local Chief Agri dealer will help you determine what bins will best meet your requirements and make sure they are expertly constructed and ready when you need them.  

Optimum Grain Protection Begins With Chief's Steel Sidewall System

Corrugated SteelCorrugated Steel Sidewalls

  • Our corrugated steel sidewalls are of 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" (1.91cm) wider than those of the closest competition, reducing the chance for material to collect on the inner wall of the farm silo.

Chief "W" Stiffeners Lead the Competition in Strength

W Stiffeners

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

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

Anchor System Provides a Solid Base

Farm Anchor System

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

Farm Galvanized CoatingStandard G115 Galvanized Coating Offers Superior Corrosion Resistance.


Chief expects your bin to be around a long time. To that end, Chief provides bins with the following coatings as standard:

  • Roofs sheets with a G140 (425 g/m2) galvanized coating. (56% thicker coating compared to G90)
  • Sidewall Sheets & 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. 


Superior Roof Design

V-Rib RoofChief 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. Grain bins from 42'-0" (12.80m) diameter through 49'-6" (15.09m) diameter have a full 4" (10.16cm) rib depth.

Chief farm bins utilize a roof system that incorporates over 30% more roof ribs than leading competitors for a stronger roof.

Fill hole diameters are now wider for easier grain filling. The roof peak opening for bins up through 37'-0" (11.28m) diameter is a generous 40" (101.6cm). The roof peak opening for bins with a 39'-0" (11.89m) to 50'-0" (15.24m) diameter is 60" (152.40cm)!


Chief J-Rib Roof

J-Rib Roof

Chief interlocking J-Rib roof is offered as an unstructured or structured design to meet your peak load requirements.

Roof panels that utilize a 2.5" (6.35cm) interlocking J-Rib design provide reduced construction time while maintaining outstanding strength.

The structured “J” rib design gives the finished roof the strength it needs to support roof stairs and most conveyors.


Convenient Door Access Options
