At Sioux Steel Company, we’ve spent nearly a century focused on providing value to our customers. What started in 1918 as a dream to start a steel corrugating business has grown into a fourth-generation, family-owned company that manufactures products that provide solutions throughout the world.

Because we know that value is just as important to you, we stand behind the quality and durability of all of our products. Sioux Steel is the company known for offering a ten year warranty on our grain systems, the longest in the industry. And, an unbelievable LIFETIME warranty on our Guaranteed gates.

Sioux Steel Company Foundation

The Sioux Steel Company Foundation is proud to support the Leukemia & Lymphoma Society. The world is a very different place these days, but one thing remains constant, cancer patients need our support. That is why 2% of the total sales dollars from this website are donated to the Leukemia and Lymphoma Society.  Beating cancer is in our blood.
