Mechanical Tubing

Mechanical Tubing is designed for mechanical and structural applications and is manufactured in accordance with ASTM A513 and ASTM A519 specifications. Tubing is often used in many industrial high-stress applications, including cylinders, gears, bearings, etc. These products are often produced to typical properties that focus on yield strength for a specific size & wall thickness. For other applications where severe forming is required, the tubing can be produced to be fit for purpose or use. Due to mechanical tubing products being used in numerous industries and applications, we have built one of the most diverse inventories to fulfill the industry’s needs.
