Angle iron is formed in a specific shape to be extremely stable and able to bear excessive amounts of pressure and weight. Normally bent into an L-shape (always 90 degrees), angle iron is often used to frame or build various pieces of furniture, supporting structures, walls or shelves.
When used in the construction of furniture, chairs, beds and tables, angle iron is used to create the basic structure of the piece and other materials are used to finish it. This provides strength and stability to withstand almost any type of use.
For containers, walls and shelves, the use of angle iron helps to stabilize the entire structure. It will not bend, bow or break and adds reinforcement in two separate directions. It is easy to work with and can be welded or bolted together to create even more stability.
The thickness of the angle iron will determine the type of jobs it is suited for. Smaller pieces are normally used for jobs where the amount of pressure and weight will be minimal, while larger thicker pieces of steel are used on walls and supporting beams of buildings that must constantly bear massive amounts of weight.
