Below is a list of Aluminum Angles manufacturers from Phoenix, Arizona. Aluminum angles are standard extruded L-shaped parts composed of 2 legs that intersect and form a 90 degree angle. Aluminum is an ideal metal for the manufacturing of these long, narrow shapes because of beneficial characteristics such as a high strength-to-weight ratio and excellent corrosion resistance. The legs of the angle are either equal or unequal in length, and often have sharp corners.
