Over 90 years of superior customer service and steel solutions.

With two locations, our steel service center will always be available to fill your order “just in time.” As your partner in solutions, our next day delivery (and even same day in certain regions) helps you manage inventory and keep your manufacturing on schedule.

OUR HISTORY

Arthur F. Maas Sr. founded Maas Hansen Steel Company in 1929, later joined by his stepson, Charles P. Hansen. In 1950, the steel service center changed its name to Maas-Hansen Steel Corporation and moved to its current location in Vernon, California.

In 2015, the company was acquired by Triple S Steel based in Houston, Texas. While still operating with the name Maas-Hansen Steel, we’re now able to serve customers and source steel outside our typical region through the national presence of Triple S Steel.

After 91 years, we’re known throughout the western region for our excellent customer service, quality, and on-time delivery. As a leading diversified metal supplier, steel service center, and solution provider, Maas Hansen Steel offers value-added metal processing services across industries.

Since 1929, our customer-first, enthusiastic team with superior technical expertise has built our success. We’re poised for the future with a commitment to excellence.
