OUR PROCESS:

Making Copper Plumbing Tube

Copper plumbing tube is one of those products that we practically take for granted, since most of the tube we use is hidden behind walls where it is never seen. This trustworthy, familiar product first came into widespread use in the United States in the 1930's. Copper is durable. If you see a 65 or more year old building with the original plumbing intact, chances are good that the material used was copper.

Despite the fact that copper plumbing tube has worked so well for so long, it was never a "high-tech" miracle material. In fact, copper plumbing tube is essentially made about the same way it always has been. The tube-making process is more complex than one might imagine and has been continually upgraded over the years to keep it energy-efficient and environmentally acceptable and to ensure that the final product meets today's stringent quality standards.
