The specific standards and systems followed by various countries or industries determine the different dimensions used to specify steel angles. However, there are some commonly used dimensions for specifying steel angles.
1. Leg Length: The length of each of the two equal legs that form the angle is referred to as the leg length of a steel angle. Typically, this dimension is measured from the inside of the angle and is denoted in millimeters or inches.
2. Thickness: The measurement of the material's thickness from one side to the other is known as the thickness of a steel angle. It is usually expressed in millimeters or inches.
3. Weight per Meter or Foot: The weight per unit length is a significant dimension used to specify steel angles. It represents the weight of the angle per unit length and is calculated by multiplying the cross-sectional area of the angle by the density of the steel. The weight is commonly provided in kilograms per meter (kg/m) or pounds per foot (lb/ft).
4. Cross-Sectional Area: The total area of the steel angle's cross-section is referred to as the cross-sectional area. It is calculated by multiplying the leg length and the thickness of the angle. The cross-sectional area is typically expressed in square millimeters or square inches.
5. Moment of Inertia: The moment of inertia measures the resistance of the steel angle to bending and is calculated based on the shape and dimensions of the angle's cross-section. It is commonly denoted as Ixx or Iyy and is expressed in millimeters to the fourth power or inches to the fourth power.
6. Radius of Fillet: The rounded corner between the legs of the steel angle is called the radius of fillet. It is measured from the inside of the angle and is typically expressed in millimeters or inches.
These dimensions play a crucial role in specifying steel angles as they provide essential information about the size, weight, strength, and structural properties of the angles. They assist engineers, architects, and manufacturers in selecting the appropriate steel angles for various applications, including construction, infrastructure, machinery, and fabrication.
