Longtime Spokane company Scafco Grain Systems Co. has been acquired by Sioux Steel Co., of Sioux Falls, South Dakota.

Scafco Grain Systems, which designs and manufactures grain storage bins, silos, handling equipment, and drying technology, has operated in Spokane for 60 years and has an international market reach, with installations in more than 80 countries.

Larry Stone, president of Spokane-based Stone Group of Companies, says in a press release, “The Sioux Steel Company is an excellent manufacturer with over 100 years of experience.”

Sioux Steel, which is a family-owned company, plans to retain all of Scafco Grain System’s employees and to keep its operations in Spokane, Stone says in the release.

A representative of Stone Group of Companies declined further comment. The terms of the sale, which was completed on March 1, and the number of employees at Scafco Grain systems weren’t disclosed in the release.

Sioux Steel CEO and President Scott Rydson says in the release, “The addition of Scafco Grain Systems Company will elevate our business, and I’m excited to welcome all the great Scafco Grain Systems Company’s employees to our family and to acquire such an impressive facility."

Scafco Grain Systems is located at 5400 E. Broadway, where it occupies 110,300 square feet of office, manufacturing, and warehouse space.

The company is the only subsidiary of the Stone Group of Companies involved in the sale.

The Stone Group of Companies, however, has nearly 400 total employees and has businesses in Washington, Idaho, Montana, Oregon, California, Nevada, and Florida, the release says. Remaining Stone Group subsidiaries include Scafco Steel Stud Co., Steel Construction Systems, CWallA Building Materials Co., Kern Building Materials, LB Stone Properties Group, and Playfair Commerce Park.
