Our History

Located in Caldwell, Idaho, just west of Boise, Superior Steel was originally founded in 1991, and was purchased by Larry Questad in 1995.

Today, the company is owned and operated by P.L. Questad and Christian Questad, who purchased the business from their father in 2012.

Over the years, Superior Steel Products has gained a reputation across the country as a reliable, proven, and quality-driven supplier of bulk storage and transportation tanks for applications in numerous industries. And that is a trend that continues to this day.
