But In most instances, it is used in camera booms, flag posts, camp, Pop-up tents, carts and adjustable racks among many more.

What is Heavy Aluminum Telescoping Tubing?

It refers to strong, versatile, and adjustable product usually used in a wide range of splicing and or telescoping applications.

You can as well use it as an add-on component in various relevant applications.

As the name suggests, the heavy aluminum telescoping tubing allows for efficient assembly without necessarily going through the hassle of drilling.

In most instances, it is used for display system supports, safety rails, fitness equipment, and assembly line framing, among others.

What’s the Difference Between Round and Telescopic Aluminum Tubing?

The length of Round aluminum tubing is rigid, while telescopic aluminum tubing is flexible. You can adjust length you need.

Round aluminum tubing is usually round just as the name suggests whereas the telescopic tubing can be round, square or rectangular.

Round vs telescopic aluminum tubing

Round aluminum tubing vs telescopic aluminum tubing

Round aluminum tubing is often provided with a nominal diameter and thickness, often known as schedule.

On the other hand, telescopic aluminum tubing is provided as an outside diameter and set of ranges of wall thickness.

Round aluminum tube is relatively rigid. Therefore, you cannot shape it easily.

On the other hand, telescopic aluminum tubing is unvaryingly rigid. As a result, you need special equipment if by any chance you want to shape it.

Mostly, round aluminum tubing is used or intended to be used for transferring fluids or gases.
