Image Alt: aluminum angles

Aluminum and its many alloys are used in almost every single industry around the world. We see this metal used heavily in manufacturing, aerospace, automotive and fabrication, and given the enormous range of benefits it offers it is easy to see why. Aluminum is low cost, incredibly strong, non-corrosive and it is incredibly flexible. Another great benefit of this alloy is that it offers excellent weldability, and this is what we are going to discuss today, in particular aluminum angles and the different kinds which there are.

The Basics of Angles

An aluminum angle is typically consists of two separate legs and these can be of either unequal or equal length. The angle will fit into a 90 degree angle which ensures maximum strength.

Anodised Angles

These angles use two pieces of aluminum which are equal size and they utilize the 6063-T5 grade. These are used to strengthen the corner of a structure and can also act as a guide when installing other materials such as wood or drywall, anything with straight edges.

Mill Finished Angles

These mill finished angles are also created with two equal parts of aluminum and can range in thickness from 25x20x3m to 40x40x3m. These are much heavier in terms of the support which they offer when compared to anodised angles, and they are used heavily in the construction industry.

Powder Coated Angles

Powder coated angles use two pieces of aluminum of differing lengths, in order to give additional support to one side of the structure in which they are being used. The grades which are used are 60606 and T66. The length of these angles is generally 2000mm and they come in both white and black color. These are predominantly used in a variety of fabrication projects where corrosion resistance may be of concern.

J Channels

This angle appears a little like the letter J hence the name, and they are finished with something of a lop side shape to them. Are often than not we see these angles used in adjustable table legs, lighting strips and a variety of construction projects.

Hat Channels

Hat channels are called so because the upside down U which the finish offers, gives the appearance of a hat which has been turned over, and because the sides stick out much like the brim of a hat. These have a slightly different use than the rest of the angles in the list because they are used less as a guide or strength, but more to secure things in place. sliding doors, cart wheels and holding wood joints together is generally where we see these angles used mostly.

Most alloys can in fact be made into these angles but manufacturers decide to use certain grades because of the benefits that they offer. This can of course change depending on what they are making and what level of support they require.
