Stainless Steel Tubing

At Zeman Manufacturing, stainless steel is a foundational material in our tubing operations, supporting precision assemblies across the medical, aerospace, energy, foodservice, transportation, and industrial sectors. Known for its strength, corrosion resistance, and clean finish, stainless steel tubing is ideal for demanding applications that require long-term performance and consistency — especially in high-purity, high-pressure, or harsh environments.

We work with a broad range of stainless steel tube shapes and sizes, including round, square, rectangular, oval, and extruded profiles. Our team supports multiple forming processes to ensure durability, dimensional accuracy, and reliable integration with complex assemblies.
