Founded in El Cajon, California, in 1959 by Mr. Wally Miller under the name W.W. Miller Company, Combo Aluminum Products was built on a foundation of innovation. Mr. Miller’s original design and patent of the Combo Sill marked a defining moment for the brand and laid the groundwork for what would become our legacy.

For more than 65 years, while many aspects of the industry have evolved, our commitment to quality and superior customer service has remained constant. That consistency has shaped who we are and how we work.

As we move forward, Combo Aluminum remains dedicated to developing cutting-edge products that serve both our established customers and emerging markets—always with the same focus on precision, reliability, and long-term value.

We deeply appreciate the trust and support of our partners and clients, and we are honored to play a meaningful role in their continued success.
