An angle is a category of structural steel shapes, just like beams, channels, and tubing. Angles, which are L-shaped pieces, are formed through the hot rolling process, in which metal (usually steel) can be rapidly transformed into structural products.
Its 90-degree angle reinforces strength and rigidity to provide structural support. It is generally found in a low alloy composition such as A36 and can be cut, welded, formed, and machined. The most common applications for angles include a variety of industries such as manufacturing and fabrication.
