Zeman Manufacturing Co. offers tube fabrication and bending services with custom fabrication capabilities, utilizing a wide range of materials such as aluminum, brass, bronze, copper, exotic metal, nickel, nickel alloy, stainless steel, steel, titanium, plastic, polyethylene, and PVC. Fabrication methods include CNC machining, ECM, forging, forming, hydroforming, laser cutting, mandrel, and roll bending. Fabricated products cover boiler parts, condensers, exercise equipment, heat exchangers, and hypodermic tubing. Available body cross sections include oval, round, and square profiles.

Fabrication features include burrless chamfering, chipless processing, flanging, sanitary, serpentine, high pressure, and purity finishes. Materials offer corrosion, electrical, moisture, rust, and UV resistance. Additional services provided include brazing, crimping, deburring, drilling, end trimming, leak checking, machining, repair, and welding. Equipment list includes SMART, UNISON - 40MM, UNISON - 50MM, Haas V-F-4, and Haas ST-20Y.

Production is supported by prototype, low to high volume, and blanket orders. Lead times are quoted on a job by job basis, with emergency and rush services available. Efficiency practices include Six Sigma yellow, green, and black belt certifications, lights out, lean manufacturing, and Kaizen/5S initiatives.

Industry focus includes aerospace, automotive, defense, electronics, HVAC, medical, pharmaceuticals, semiconductor, telecommunications, transportation, oil and gas pipeline. Compliance is maintained with industry standards such as ANSI, AS, ASME, ASTM, AWS, CE, CSA, DOT, FAA, FDA, ISO, Mil-Spec, NADCAP, QS, RoHS, SAE, and TS.
