Exterior Knurling Tubing

While foam grips are great for many applications, some applications require tubing that will not slip through hands or gloves. Testrite has the ability to add a knurl to the outside of our tubing to increase friction between the user and the tubing. As shown in this example, Testrite added two grip sections, showing the operator where to place each hand.

Round Telescopic Aluminum Tubing

This round, drawn aluminum tubing is ideally suited for custom telescopic tubing assemblies. Our round telescopic aluminum tubing is manufactured to tight tolerances +/- .005” on the outside diameter and wall thickness, our aluminum tubes are available in 1/8" increments from 3/8" diameter up to 1-1/2" diameter. Typical wall thickness of each tube is .038”.

Non-Rotating Telescopic Aluminum Tubing

Non-rotational tubing is U indented and will telescope but not turn.  Manufactured to tight tolerances it is available in 1/2" thru 1-1/4" diameters in 1/8” increments.  Tube assemblies are typically constructed using a round outside tube with inner non-rotational ones.  Therefore a 1-1/4” non-rotational tube can telescope inside a 1-3/8” round tube.

Round Steel Telescopic Tubing

Round steel tubing is suited for applications calling for extreme strength or need to weld to a steel plate or base. Testrite typically stocks only 7/8” and 1” diameters, but can readily get others in quantity.  The lock we recommend for steel tubing is our “B” collar lock.  Steel tubing requires a powder coated finish which we can supply in any color.

Oval Aluminum Tubing

Testrite stocks a variety of aluminum oval shapes that are available for purchase a la carte. These include ovals with threaded channels, ovals with openings on each end, ovals with grooves, and more. If you’re in need of an aluminum oval for use as an upright, crossbar, or another need, reach out to us today and let us know how we can help.

Gold Aluminum Tubing, Gold Steel Tubing, & Brass Plated Parts

Bright dip gold anodized aluminum tubing is available for order, as are brass plated steel parts and thin brass plated steel tubing. Gold anodized telescopic tubing is made to order, often paired with our aluminum clutch lock in a matching gold anodized finish.

Etched and Clear Anodized Aluminum Tubing

Etched and clear satin anodized aluminum tubing is an aesthetically beautiful and cost effective finish that properly “seals” and protects the aluminum tube though some surface imperfections are normal and visible.  We stock all our aluminum tube diameters in this finish, both rounded aluminum tubing and non-rotational aluminum tubing.

Mill Finish Aluminum Tubing

Mill finish – i.e. unfinished as received from the mill.  Will show imperfections and is not sealed. Thus, if you were to run your hand over it, your hand will show black smudges.  Bypassing anodizing does save cost and is good in applications for parts that will not be seen. We stock all our aluminum tube diameters in this finish, both rounded and non-rotational.  

Black Matte Telescopic Tubing

The Black Matte telescopic tubing finish is a handsome and popular choice.  All our telescopic tubing diameters are typically stocked in limited quantities either anodized or powder coated black matte (practically indistinguishable from each other).  Black matte does cost more than etched and clear satin anodized.  

Logo Printing

Testrite can imprint full color logos on a variety of surfaces, including our round aluminum tubing and our flat steel bases. Logos print with incredible detail and vibrancy. Ability to imprint and durability will vary by application – reach out to our team to discuss today!

Custom Powder Coated

Powder coating can be done in any color (in quantity).  Supply a specific pantone color code and we can get a close powder match. Powder coating is an excellent choice – covers well, is durable, and is not affected by sunlight.  The application process is environmentally friendly and service is speedy.
