Round Tube

Show full description

round-tube-large-new-min-4superZoom-main

Round Tube

We carry Round Metal Tubing in Alloy Steel, Aluminum, Brass, Carbon Fiber, Carbon Steel, Copper, Nickel, Stainless Steel, and Titanium. What's the difference between pipes and round tubes? Pipes are passageways, while tubes are structural – meaning round tube sizes will be true to the listed dimensions while pipe will be a nominal dimension. The round metal tubes for sale in our warehouses also will not couple with pipe fittings.
