How To Bend Aluminum Channel?

Bending an extruded aluminum channel isn’t as easy as it may seem.

This requires you to have a particular set of skills and experience to make that consistent curve at some sections with ease. However, some of the extrusions are easier to bend than others.

One of the most notorious aluminum channels when bending is the U-channel.

It can be a challenge even though you have the experience of doing it. Roll bending U-aluminum channel

You can also try to bend it with your hand, but it can deform and damage the aluminum channel.

How To Cut Aluminum Channel?

Cutting an aluminum channel can sometimes be challenging.

Because if you apply too much force to the aluminum, you can spoil it while cutting, and also, too little of it won’t cut the channel.

So what’s the best way to cut the aluminum channel?

You can use many different tools to cut the aluminum, such as the miter saw and the cold chisel.

Follow the steps below to cut the aluminum channel:

Using a miter saw:

You will need any of the following types of blades to get a good cut on your channel with a miter saw.

  • Circular blades. These blades are used in cutting aluminum channels in tilting angles and the desired shapes.
  • Coarse blades. They are used to bring the abrasive cutting to the aluminum to have a fine finish.
  • Razor blades. They are sometimes called the best blades if you are looking for a high-precision cut on the channel.
  • Sharp-cut blades. This will be perfect if you want sharp cuts on your aluminum channel.

Procedure for using the miter saw:

  • Choose the right miter blade.

To know which blade to use, get to know the thickness of the aluminum you want to cut first.

Next, ensure that you use the specified blades for cutting the aluminum. For example, you can use a specific grade of carbide-tipped blades depending on the type of metal and its thickness.

  • Secondly, mount the blades.

Remove the already mounted blade by opening the blade guard, taking out the first blade, and replacing it with the new blade.

  • Clamp your aluminum channel.

You can use a C-clamp to hold your aluminum channel in place as you cut it.

Clamping ensures that the aluminum channel stays in position and doesn’t move around.

  • Lastly, cut through the aluminum channel with the miter saw.

Now, slowly lower the saw on the aluminum channel to cut it.

Using a cold chisel:

Follow the process below to cut the aluminum channel with a chisel

  • Get a cold chisel that is a little wider than your aluminum channel.

The standard sizes are 1 inch, ¾ inches, ½ inches, and ¼ inches. Your chisel should be appropriately sharpened before cutting.

  • Adjust your aluminum channel at the center of the cold chisel’s jaws and ensure it’s tightened.

Hold the chisel tip perpendicularly against the metal and use a ball-peen hammer to strike the chisel’s handle for you to cut through the aluminum channel.

  • Strike the extruded aluminum channel until you feel a notch in it. At that particular point, you’ll notice a snap, and you will be able to cut through it with your hands.

If it takes too long to cut the aluminum channel with a chisel, you should use a miter saw instead.

How To Straighten Aluminum Channel?

Aluminum channel is a very malleable product. You can accidentally bend it without knowing it.

You shouldn’t assume the aluminum channel is spoiled, but you can straighten it yourself with the right tools.

Aluminum F channel to be straightened

Aluminum F channel to be straightened

Follow the steps below to straighten aluminum channels:

  • Use your hand:

Using your hands, try and straighten the aluminum channel. But depending on the thickness of the aluminum channel, you might not be able to bend it.


  • Use a heat gun:

Lay the extruded aluminum channel on a solid surface or a flat surface like on the concrete floor.

Next, use a heat gun to warm up the bent part to straighten it with ease.

Next, try to straighten the aluminum channel as it heats up. Continue heating it as you bend it until you straighten it.

Next, use a rubber mallet to hit the heated aluminum channel to avoid bumps.

Your aluminum channel is now ready to be reused.

Can I Use an Aluminum Channel To Build A Shed?

Yes, you can use an aluminum channel to build a shed. They are considered durable and can last a long time without wearing and tearing.

Some good-quality extruded aluminum channels can survive harsh weather conditions and resist warp and termite infestation.

They need little maintenance, and they are easy to clean.

However, you do not need to repaint them every year as you would with other materials.

Aluminum channels are very affordable, and they’d save you money over other metals like steel.

The exposure of the metal sheets may cause them to corrode and rust with time. But aluminum is an excellent choice to use for channels because aluminum is corrosion resistant.

You can also overcome corrosion by insulating your shed or using paint to prevent corrosion.

How Is Aluminum Channel Made?

The aluminum channel is made by pressing in billets or logs through a channel die shaped under a high-pressure ram.

You can use two methods to make the extruded aluminum channel. These are direct and indirect.

  • Indirect extrusion:

This way, the billet is kept still when the ram pushes the die.

  • Direct extrusion:

This method presses the ram down on the billet to force it through the die.

There are different ways to extrude aluminum channels, such as:

  • Hot extrusion:

The aluminum extrusion is heated to between 500-600 degrees Celsius in this process. This is done inside vacuum oxidation forestall.

  • Cold Extrusion:

The billets and aluminum channel are handled and shaped at room temperature in this process.

How Long Is The Aluminum Channel?

Aluminum channels can have different lengths and different thicknesses, sizes, and estimated weight.
