Straight Aluminum Tubing 5in O.D. x 18in Long

The Straight Aluminum Tubing 5in O.D. x 18in Long is a precision-engineered structural component designed for fabricators, engineers, and DIY builders who demand reliable material for custom frameworks, assemblies, and mechanical projects. Its straight profile and consistent dimensions make it ideal for applications requiring precise fit and alignment, including machinery mounts, support structures, spacers, and connector assemblies. Built from lightweight yet durable aluminum, this tubing delivers the strength-to-weight ratio needed for both stationary installations and portable equipment builds.

Constructed from polished aluminum with a 2.4mm wall thickness, the Straight Aluminum Tubing features a 5-inch outer diameter and 18-inch length, providing substantial structural capacity while remaining corrosion-resistant and easy to machine or weld. The polished finish not only enhances appearance but also offers protection against oxidation and environmental degradation, extending service life in both indoor and outdoor environments. At 3.03 lbs, this tube maintains excellent portability without sacrificing rigidity, making it suitable for applications where weight control is critical yet strength cannot be compromised.

This aluminum tube benefits fabricators working on custom enclosures, frame assemblies, and structural reinforcements where precision tubing dimensions are non-negotiable. Builders value its consistent wall thickness for welding integrity and its polished surface for both aesthetic and functional durability. The 18-inch length accommodates mid-range structural spans without requiring splicing while remaining practical for inventory and transport. Whether cut to shorter segments or used as-is, this tubing integrates seamlessly into modular designs and retrofit projects requiring straightforward, reliable material specifications.
