Tegra Corporation, formerly known as Terminal Grain, was founded in 1918 on Midwestern values of honesty, trust, fairness, and mutual success for our customers, employees, and our company. Although we’ve grown from originally operating grain elevators in Iowa, South Dakota, and Minnesota, our values have stayed the same.

Focused on sustainable growth, Tegra Corporation is the parent company of Big Soo Terminal, Big Soo Warehouse, and Sioux Rubber & Urethane.  Tegra Corporation provides management, advice, coaching, and back-end support for our portfolio of companies. We are focused on our best-in-class industrial operations throughout the Midwest and continue to explore opportunities for growth through partnerships, acquisitions, and start-ups.
