Angle Bar is one of the widely used steel sections in the construction industry and metal structures, which is made in the shape of the English letter L (L‑shape). 

It has two wings (sides) that are connected at an angle of 90 degrees. 

For example, a 40x40 corner means that each wing is 4 cm wide.

🔹 Types of corners

1. Equal wing angle: 

Example: L40x40x4

2. Uneven wing angle: 

   The width of the wings is different. 

Example: L50x30x5

3. In terms of production method:

• Fabric Corner: Produced directly from hot rolling. 
• Percy corner: it is made by cutting and bending the steel sheet.

Corner applications

• Construction of metal structures (frames of buildings, columns and beams)
• Reinforcement of corners and angles in shelves and frames
• In electricity and telecommunication projects, masts and bridges
• Use in cornering of walls for the strength of the form and facade

Advantages of using corner

✅ High strength in bearing pressure and force 

Especially in corners and structural joints

✅ Easy installation and connection 

It can be easily connected to other parts by welding or bolting. 

Flexibility in structure design 

It is produced in different dimensions and thicknesses, so engineers choose the right type and size according to the needs of the project. 

Long life and durability 

If anti-rust and protective paint are used, it has good resistance to rust and environmental conditions. 

✅ Being affordable 

Compared to many other stages, the cost of its production and installation is lower.
