Metal angle, also known as steel angle iron, angle bar, L - bracket, or angle steel, is a form of structural steel. Comprising two legs that form a 90 - degree angle, it is utilized in structural applications as well as general fabrication.
Meanwhile, angle iron can be divided into equilateral angle steel and unequal angle steel.
Metal angle ranks among the most fundamental and extensively used structural steel components in the fields of construction and engineering.

Furniture Manufacturing：
In furniture design, angle steel can be a frame material to enhance stability and durability. Its simple look also adds a modern, industrial style, fitting some simple - style furniture.
Automobile Manufacturing：
Cold - formed angle steel is often used in car body frames and chassis parts. Its high dimensional accuracy and workability meet the auto industry's needs for high - precision and complex - shaped parts, while ensuring body strength and safety.
Construction Industry：
In building structures, angle steel is commonly used for frames, supporting beams, columns, and stair handrails. It plays a key structural role in residential, commercial, and industrial buildings, ensuring stability and safety.
Mechanical Manufacturing：
It's used to make components like frames, brackets, and protective fences of machinery. Angle steel's high strength and good workability meet machinery's structural requirements and facilitate processing and assembly.
Power Engineering：
For power facilities such as transmission towers and substations, angle steel is a main structural material. It can bear power equipment's weight and natural forces like wind and snow, ensuring reliable operation.
Features of Metal Angle Iron
The unique right angled cross-section gives the angle steel excellent mechanical properties under pressure and tension. Different materials of angle steel, such as low-alloy high-strength angle steel, can meet heavy-duty requirements.
Equilateral angle steel has a symmetrical structure and uniform force distribution. Unequal angle steel can be designed for specific stress conditions to ensure overall structural stability. In architecture and mechanical structures, it can effectively resist external forces.
Angle steel is easy to cut, drill, and weld. Both hot-rolled and cold-formed angle steel can be easily combined with other materials to meet engineering design and manufacturing requirements, thereby improving production efficiency.
Angle steel has diverse specifications in terms of size, material, and process, and can be applied to many industries, from simple building decoration to large-scale industrial projects, demonstrating extremely high universality.
