The Bunger Difference

Locally Crafted

Bunger Steel is a quality, full-service manufacturer of all kinds of steel buildings including Commercial, Industrial, Residential, Institutional, Agricultural, Airplane Hangars, Mini Storage, Churches, and more.

Since its conception in 1974, Bunger Steel has been family-owned and operated. Today, we are Arizona’s largest steel building and components vendor, and have over 40,000 projects constructed in the Southwestern United States.

From our turn-key classic garage to the most sophisticated building systems, you will discover the difference working with the Southwest’s premier, pre-engineered steel building manufacturer.

There are many advantages to choosing Bunger Steel to manufacture your steel building that go beyond working with a trusted company with decades of industry experience.

For 45 years Bunger Steel has been dedicated to creating high-quality and innovative custom engineering for everything from roof panels to manufacturing plants.

Build Something Different

Bunger Steel remains committed to the in-house fabrication of our components and buildings. We fabricate pre-engineered metal buildings to your custom specifications not as a one-size-fits-all. Because of this, our buildings often include details that others in the industry add on after the fact.

When you buy a Bunger Steel building, you are not only investing in a steel project but obtaining convenience and peace of mind. You can trust Bunger Steel to deliver the building you need and the service you deserve.
