Ladder & Cage System
Manufactured from sturdy, galvanized steel tube that fit the bin side wall with each ring. Four bolts simplify attachment. Farm Bin Floor Supports ImageNo drilling, extra brackets or hardware. Plus no bolts to loosen!

Floor & Floor Support System
Designed to develop equal air pressure under the entire floor surface, floor supports are heavy gauge, galvanized steel formed with ten vertical ribs to support grain depths up to 37 feet.

Auger Hopper
Farm Bin Power Sweep ImageThe auger hopper door baord is available on 15' to 24' diameter bins. Door frame is the same sytle on larger bins.

Power Sweep
Made with galvanized tube, intermediate sumps and control pipes. Superior to painted black steel. Heavier components and heavy duty clutch provide a longer work life.

Farm Bin Transition ImageLJI Floor Support System:
1) Strength per square foot of floor
2) Unobstructed air movement
3) Ease of erection and stability
4) Savings in total bin cost

Verticle supports offer added strength at the entrance opening. The aerodynamically engineered “channel-flow” shape delivers air between the fan and bin plenum. Multiple sizes fit every size fan and heater.

Farm Bin Fans

Axial Fans
Sioux Steel's Axial Fans cast aluminum airfoil blade ensures economical maximum airflow at lower static pressure.  Our highly trained engineers have created precision-balanced blades to achieve vibration-free operation.  The hub on the blade prevents backflow air leakage at higher static pressures.  They have also designed the housing with close tip clearance for maximum airflow.  Airflow is increased by not allowing air to blow back through the blade and the housing for greater efficiency, providing the most efficient Axial Fan on the market today.

Centrifugal Fans
Centrifugal FanSioux Gold Quality Centrifugal fans are quiet compared to other leading manufactured fans.  They are bench-tested prior to shipping in order to ensure that our customers are getting a top quality product that works properly from day one.  Our highly-trained engineers test motor amperage and temperature under long-term, maximum-load conditions to ensure that the motors will stand up under tough operating conditions.  Adjustable legs on fans allow easy leveling and support while giving more flexibility for adjusting to inconsistencies in a concrete pad.

Farm Bin Standard Features

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.

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.

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.

Farm Bin Compression Ring ImageMan-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-freiendly man-way!

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.

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.

Farm Bin Roof Image 01Roofs
The strongest roofs available! Our 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.

Farm Bin Roof Image 02Roof 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.

Ladder and Cage Systems

Ladders are manufactured from sturdy galvanized steel tube that fit the bin side wall with each ring.  It's safe and strong.  Four bolts simplify attachment.  The welded design ensures stability.  No drilling, extra brackets or hardware and no bolts to loosen!
