From humble beginnings more than 85 years ago, Mueller Inc. has grown to become the leading manufacturer of steel buildings and residential metal roofing in Texas and the Southwest. The company is still headquartered in Ballinger, the small West Texas town where it was founded. What accounts for Muellers longevity? One vital factor is its manufacturing capabilities. While other businesses have outsourced their manufacturing processes, Mueller continues to make its own products the old-school, American way. With in-house engineering and strict quality control, Mueller is able to deliver unbeatable quality and value. Another key factor in Muellers success is the dedication of the companys 750+ employees. They have a reputation for going the extra mile and beyond for customers. Call or walk into any of Muellers 33 locations across the Southwest and you can experience it for yourself. Plus, our IronClad Guarantee ensures that we're always there for you. If there's a problem with your metal roof or steel building, we guarantee to make it right.
