Benefits of DOM Tubing

Plymouth® DOM mechanical tubing is the number-one choice of many original equipment manufacturers and fabricators serving multiple industries due to its many advantageous properties:

  • Exceptional Strength and Formability: Cold drawing increases yield and tensile strength through work hardening, allowing for tight-radius bending and flaring.
  • Excellent Surface Quality: The mandrel-drawing process produces a superior, scale-free finish on both OD and ID surfaces, reducing secondary machining and preparation for plating or coating.
  • Above Standard Dimensional OD and ID Precision: Our specialized DOM process ensures superior concentricity and wall thickness uniformity, delivering the tight tolerances required for high-performance mechanical assemblies.
  • High-quality finished product: Produced under ISO 9001:2015 and PED certifications at our Eupora mill, every length of tubing is engineered for consistent performance.
