National Tube Supply (NTS)

Company Profile

National Tube Supply has been a leading supplier of carbon & alloy mechanical tubing across North America since its founding in 1990. NTS provides DOM, CDS, HFS, and chrome bar in a wide range of sizes, grades, and tolerances. And thanks to a selection of value-added services, NTS can tailor product to a customer’s specific needs: honing, induction-hardening, skiving, boring, and more. 

The sales team at NTS averages more than 20 years of experience. And thanks to private ownership through the Bianco Group, plus five warehouses across North America, NTS can source and provide a larger supply of carbon & alloy tubing than other suppliers in the industry—and most orders are ready to ship next day.

NTS carries a wide stock of mechanical tubing: Carbon steel Drawn Over Mandrel (DOM) and Cold Drawn Seamless (CDS) in sizes 0.375” outside diameter (OD) to 16” OD.

Chrome bar products are also available in a broad range of sizes, from .500” diameter to 12” diameter; grades; and chrome thicknesses of .0005”, .001”, or .002” per side. And NTS’ chrome bar is induction-hardened to stand up to the most demanding environments.
