Like Columbia specialty, Cambridge-Lee has evolved into a major player in the Commercial and Industrial Marketplace through service and quality brands of manufacture.  Cambridge-Lee Industries entered the copper tube industry in 1955 as a small distributor serving  the U.S. plumbing market. Since then they evolved into one of the world’s largest distributors of copper with sales offices in every corner of the globe. In 1993 one of Mexico’s largest conglomerates, acquired major U.S. producer Cambridge-Lee Industries  Then, in 1996, Cambridge-Lee purchased Reading Tube Corporation,  a major U.S. producer of copper tube. As a result of the acquisition, Cambridge-Lee has become one of the world’s leaders in the manufacture and distribution of copper tube for water supply, air conditioning, refrigeration and a variety of commercial applications.
