At Zeman Manufacturing, copper is one of the key materials we work with to support high-performance assemblies across medical, energy, HVAC, foodservice, and electronic industries. Known for its excellent thermal and electrical conductivity, copper tubing demands careful handling and precision processes—especially in small-diameter and thin-wall configurations.
Our team works with a full range of copper tubing types and shapes, including round, square, rectangular, and oval profiles. We support a variety of manufacturing processes, such as welded, drawn over mandrel (DOM), seamless, annealed, heat treated, flash controlled, straightened, and extruded tubing.
