Seamless Mechanical Tubing / Hollow Bar

Seamless Mechanical Tubing also known as Hollow Bar is a cost-savings alternative to round bar.  Hollow bar minimizes machining costs, increases part yield, and reduces scrap because it includes an Inner Diameter (ID) designed to efficiently yield certain finish parts.  Dover Tubular Alloys offers an extensive selection of seamless mechanical tubing / hollow bar sizes and cuts all sizes to length.
