Product Details

Aluminum round tubing, often called round tube, is available in the 6061-T6 alloy with small and large diameters. Tubing is measured using the outside diameter (OD) and wall thickness. Tubing typically has tighter manufacturing tolerances than pipe with uniform dimensions and smooth interior walls. Typical applications include structural supports, CB antennas, boat and swimming pool ladders, structural framing, car wash wands, filler tubes, and more. At Cut2Size Metals, discover tubing available in both standard lengths and custom-cut lengths, tailored to your project requirements. Most orders are shipped the same day in our high-quality packaging, safeguarding your materials.
