Structural Design of Steel Angle

Hi and welcome to metal supermarkets the convenience stores guide for metal.  We will talk about structural design of steel angle.

Structural Design of Steel Angle

Structural steel is an important building material which consists of three main shapes Angle Channel and Beam. Each one has a unique cross section, mechanical properties and a specific way to measure it. In its development there are many other types such as steel plate, hollow, steel pipe and others

In this explanation blog series we’ll take a closer look at each type starting with Angle. Structural angle is a hot rolled product that is formed by rolling steel through a series of rollers and dies giving it a finished L-shaped corss section. The two perpendicular portions of structural angle are called the legs. They can either be the same length known as equal legged angles or different lengths known as unequal legged angles.

Rounded Structural Design of Steel Angle

The rounded inside angle is called the fillet

The rounded inside angle is called the fillet and the radius of the fillet is aptly called the fillet radius. The size of the fillet radius is not always provided but needs to be considered if the angle will be used to cover a 90 degree angle. If the fillet radius is required to be 90 degrees standard structural angle will not work in this application. Steel angle is measured using three dimensions the length of each leg and the leg thickness.

In the case of unequal legged angles the length of the longest leg always comes first. When measuring the lengths of each leg you always want to measure the outside where the leg is longest. In this case our equal legged angle is 1.5″ By 1.5″ By 3/16″ Typical applications of structural angle include structural reinforcement, for framework, shelving, or for repairs on many products. Hopefully this this will help you the next time you have a project that requires structural angle.

Stay tuned for the next part in this explanation blog series where we will take a closer look at structural beams. If you need more information about structural design of steel angle for your next project,  learn it carefully before you jump into metal supermarkets. If you jump straightaway to the market, you will confuse.

Metal market is one of the world’s largest supplier of small-quantity metals carrying over 8,000 types, shapes and grades of metal including various types and sizes of angle cut to size and ready fast. (NH)
