Steel angle sizes vary depending on the specific application and requirements. The dimensions typically include the leg length, thickness, and sometimes the length of the steel angle. Here is a basic chart for common steel angle sizes.

Key Terms:
Leg Length (A x B): Refers to the length of each leg of the angle steel, usually measured in millimeters (mm).
Thickness (t): The thickness of the steel in millimeters (mm).
Weight (kg/m): The weight of the angle steel per meter, measured in kilograms (kg).
Width (mm): The width of each leg, typically equal to the leg length in equal angles.
These sizes are commonly available, but custom sizes can also be manufactured to meet specific requirements. The weight per meter helps in calculating the total weight needed for a project, which is essential for shipping, handling, and structural load calculations.
