How Much Weight Can Aluminum Square Tubing Hold?

The average estimated weight that aluminum square tubing can hold ranges from 10,000 to 75,000 pounds.

However, the weight holding capacity of aluminum square tubing depends on the average length. If the aluminum tube is supported at both ends, the total weight will lie at the center of the span.

Different series of aluminum square tubing are available with various weight holding capacities.

If we talk about the weight holding capacity of 6061 aluminum, it will range up to 35,000 pounds.

The outer diameter of aluminum tubes also changes the weight holding capacity. Thus, you can apply different weights on aluminum tubes depending on their thickness.

How To Expand Aluminum Tubing?

Two different methods are commonly used to expand aluminum tubing in well-defined ways. These methods are given as under:

  • Ram Forming Expansion

The first method employed in expanding Alu tubes is ram forming expansion. It includes the usage of a tapered die.

This tapered die acts as a mold. Extreme pressure or force is applied to the mold. Thus, it will make the tube’s end embedded into the die.

In this way, the application of high-pressure forces on the aluminum tube molds expands its surface area.

  • Hydraulic Expansion Die

Besides the ram forming expansion, hydraulic expansion is another method for expanding aluminum tubing in no time. In this method, a wide variety of finger-size fragments are used.

These fragments can easily open and close rapidly. Thus, upon opening, they put pressure on aluminum tubing with the help of a hammer.

So, applying pressure through the hammer will cause the aluminum tubing to expand.

The expanding ability of the Alu tube depends on its range and size. Thus, you can adjust the pressure depending on the size or thickness of the aluminum tube.

How Is Aluminum Tubing Made?

Common steps for making aluminum tubing are described as under:

  • The manufacturing process of aluminum tubing begins with the highest quality of slug or blank
  • The manufacturers fed the slug or blank into the different sets of tools that are used to extrude them
  • The extrusion tools are then used to press the rough aluminum structures into a compact tube form
  • After the extrusion process, the next step is trimming
  • Trimming machines are used to cut the extra parts of aluminum tubes to a specified length on both ends
  • Threading is the next step after trimming
  • It is done at about 460 degrees centigrade
  • After threading, the spray is applied on aluminum tubes to provide them with extra shine

How To Anneal Aluminum Tubing?

The annealing of aluminum tubing starts by heating the tubes at about 775 degrees Fahrenheit and is followed by a cooling process.

This cooling process is done for about 2-3 hours. These tubes are cooled at 500 degrees Fahrenheit with a rate of 50 F per hour.

No doubt, it is pretty hard to deal with aluminum tubes at this temperature, but many manufacturers use fabricated tools.

Other than this, the basic principle to anneal almost every size of aluminum tube is to heat it close to its melting point and allow them to cool down slowly.

So, the primary purpose of annealing aluminum tubes is to make them more malleable by softening their crystalline structures.

How To Connect Aluminum Square Tubing Without Welding?

The best way to connect aluminum square tubing without welding is to use a reliable propane torch and even aluminum brazing rods.

They are the quickest ways to connect aluminum square tubing and bond it without using a welder.
