Farm Bin Accessories
Steel Strength
Superior farm bins are built with Grade 55 steel for high strength and coated with G-90 galvanization for corrosion resistance.
- Superior bins use 3/8-inch sidewall bolts and JS500 Grade 8.2 bolts, which are up to seven times more corrosion-resistant than standard bolts.
- Each bin includes a pre-rolled base angle with a foam gasket to seal out moisture and comes with a lifetime bottom ring warranty.
Roof Panels
Superior farm bins feature a durable roof system engineered to handle 40 lbs/sq. ft. snow loads and 105 mph winds, with peak load options of 8,000 or 15,000 lbs.
- Rigidized 3-1/2-inch roof ribs lock into a wind ring for added strength, and corrugated flat panels with drip edges enhance durability.
- Moisture is kept out by UV-resistant roof vents with raised ridges, while a continuous eave angle evenly distributes roof load.
- Wind rings and triple-break peak rings ensure structural integrity and reliable weather protection.
Bin Doors
Superior farm bins include a heavy-duty 66-inch door with secure latches and wide-opening panels for easy access.
- Standard features include a bin step, roof ladder, and interior ladder.
- Optional upgrades like galvanized stairs with a large platform, exterior ladders, and a bolt-together peak walk-around improve safety and durability.
- Roof ladder handrails are also available for added security.
Herculok Floors
Superior’s Herculok floors use an interlocking design with locking tabs and are formed without removing steel for added strength.
- Ribbed flashing supports taller eave heights and improves sweep wheel traction.
- Heavy-duty floors are standard on 48′–54′ bins and optional on 15′–42′ bins.
- Z-supports with vertical breaks and welded supports increase floor stability.
- Optional Canola floors feature 8% openings for improved airflow with small grains.
Unload & Power Sweep Systems
Superior’s 11-inch U-trough unloads up to 6,000 bushels per hour without damaging grain.
- Hinged discharge covers latch open for use and closed for protection. Rack-and-pinion gates with roller bearings allow easy sump operation.
- An independent next-to-center sump provides a backup if the center sump plugs.
- Double flighting increases unload capacity, and a 16:1 gear reduction drives the sweep through grain efficiently.
