About Us

Our Top Priority Is Your Bottom Line

Interstate doesn’t work with companies; we work with people. Because many of our customers work in mining, energy production, construction, trucking, manufacturing and other fast-moving, time-sensitive industries, we understand the pressures you’re under and why eliminating downtime is critical to your success.

With dozens of locations across Minnesota, Montana, Nebraska, North Dakota, South Dakota, Wisconsin, Illinois, Indiana, Iowa, Michigan, Wyoming, Kansas, California and Arizona, we are always striving to add products and services to our company that will better meet the needs of our customers. Our strength, however, lies in the depth of our knowledge, the expertise of our people and the commitment of our company to be a valued partner for our customers.

Our Mission

We commit ourselves to excellence, integrity, improvement and teamwork. The first priority of each employee is to exceed our customers’ expectations.

Anyone can sell you a part, and some can even offer you service. What sets our business apart is our ability to solve problems. In a world full of commodities, the knowledge and expertise of our people is something nobody else can replicate.
