How do I become a Sioux Steel dealer?
To become a Sioux Steel authorized dealer, please contact a Sioux Steel Sales Manager:

      Commercial & Farm Bins: 605-336-1750 or 800-557-4689
      Pro·Tec Buidlings: Lynn Ziegler, 605-965-4217
      Livestock & Koyker: Leo Baumgart, 605-647-1129

Can I buy products directly from Sioux Steel?
Sioux Steel products are sold through a distribution network to assure that they are properly serviced and represented when they are sold. Please contact your local dealer to discuss product availability.


How do I obtain the erection manuals for my grain bin?
An owner's and erector's copy of the erection manuals are shipped with your bin and can be found in a plastic bag in the grey hardware tub. If the manuals cannot be found, please contact your dealer, who can download a copy for you. 

What type of foundation do I need for my grain bin?
We recommend you contact a foundation engineer to obtain a certified foundation design. You may, however, contact Sioux Steel’s engineering department to obtain non-certified foundation recommendations for bidding purposes only.

What is the required spacing for my bin aeration floor supports?
The information for aeration floors, including support spacing, can be found in the Grain Floor Systems manual (manual no. 178468). This manual can be found in the floor flashing hardware pail. If the manuals cannot be found, please contact your dealer, who can download a copy for you. 


Does Sioux Steel sell greenhouses?   
The Pro·Tec building covers let 20% of the UV light into our buildings. Pro·Tec buildings can be used as greenhouses because this is enough light for mature plants.

If I want color on my cover, does it cost more? 
No, the cost is the same. You can choose between a number of color options available.

Can I erect my building by myself? 
You can possibly erect our smaller single tube buildings yourself. However, larger buildings become much more complex and we recommend obtaining a qualified contractor to erect those buildings. Keep in mind that building problems resulting from improper erection are not covered by warranty. Specific tools and equipment will be required to erect Pro·Tec buildings. Consult the erection manual for your particular Pro·Tec building for further information.

Can I get a freight quote for my building?   
Please contact PlainsXpress at 1-605-647-1177 to obtain shipping quotes. You will need the zip code that it would ship to and whether it is going to a business or residence. Unload equipment will be required at the delivery site to offload building components.

Livestock Gate Promotion:
Who Has The Most Sioux Steel Gates/Panels?

June 2013

Congratulations! Bad River Ranch of Ft Pierre, SD!

This ranch has over 7,000 bison on thousands of acres of land. to help contain the bin, they installed more than 1,400 Sioux Steel Victory gates. When asked what drew them to the Sioux gates, Tom Lafaive said "The options, durability were the most important reason. And the heavy duty hinges were icing on the cake and it's really made a different."

Watch more of Tom's thoughts on Sioux Steel Victory gates.

August 2009

Congratulations! Steinheuser Farm of Tulare, SD!

This 3 generation, family-owned operation owns an astounding 287 Sioux gates and panels! Stan, his boys Mark and Jay, and grandson Lance Steinheuser will receive 5 free gates with hinges from their local Sioux dealer, Jensen's in Huron, SD. Jensen's have been providing this family with gates for over 40 years. When asked why they buy Sioux gates, Stan said "Strength, reliability, and their local dealer who cares about their operation."
