WELDED TUBING
Welded Tubing provides aluminum tube customers with an alternative to drawn and extruded tube. Welded tube is on average 15% stronger than extrusions and can offer equal and sometimes greater strength at lower gauges. Welded tubing is utilized many applications such as outdoor furniture, healthcare equipment, household fixtures, and athletic accessories. Welded tube has also found its way into applications where steel tubing is traditionally used.
Coltwell offers both round and square welded tubing in a variety of alloys and tempers within the 3000 and 5000 series, as well as a variety of sizes:
