Founded in 1966 by A. Leo Howell, CMC Howell Metal was built on the concept of providing a quality product with the highest standards of customer service. As a moderate-size organization, we are able to tailor our manufacturing and delivery systems to meet your specific needs. We manufacture: Type K, L, M, and DWV straight lengths; Type K and L coils; Type K and L Oxy/ACR straight lengths; and refrigeration coils and linesets and maintain a network of vendors to supply additional types and sizes. Bar coded material is available in both straight lengths and coils as well as in cut lengths for the do-it-yourself market.
