.038" Wall Round Aluminum Tubing - Telescopic Compatible
We stock tight-tolerance drawn over mandrel (DOM) round aluminum tubing with a .038" wall. We refer to this tubing as Telescopic Compatible because it is manufactured to very tight tolerances on wall thickness, ovality, and straightness to ensure it will telescope smoothly. We stock our round telescoping tubes in 1/8" increments for easy nesting and design flexibility.
This .038" round aluminum tubing is guaranteed to telescope one size inside the next, making it ideal for adjustable assemblies, collapsible structures, and lightweight mechanical applications. This tubing is slightly thicker than .035" wall aluminum tubing, providing a balance of strength and low weight. These are true nesting aluminum tubes, where each size slides cleanly into the next size up without binding.
These proven .038" Wall round telescoping aluminum tube shapes are available in multiple finishes to meet your design and performance needs — including as silver anodized round tubing, black anodized round tubing, and mill finish (raw aluminum). This material is proudly Made in the USA, ensuring precision quality.
Engineered from 6063-T5 aluminum alloy, this material offers great machinability, corrosion resistance, and surface finish quality. It is the preferred choice for architectural, display, industrial, and OEM applications where appearance and function both matter. The anodized finishes provide enhanced durability and an attractive, professional look, while mill finish offers a cost-effective raw option ready for your own finishing or powder coating.
Common uses for this lightweight hollow aluminum telescoping tubing include telescoping poles, display frames, adjustable poles, camera stands, tripods, flagpoles, furniture supports, DIY projects, and custom assemblies. Because of its tight-tolerance manufacturing, designers and engineers trust this tubing for reliable, repeatable performance in applications requiring precise sliding or telescoping action.
Whether you need a few lengths for prototyping or production quantities for OEM manufacturing, Testrite Aluminum provides wholesale pricing on bulk purchases of aluminum tubing along with consistent quality, fast delivery, and the in-house capability to cut to your required length.
