Square Angle
Square angle is an angle iron with square legs, creating a right angle. This type of angle iron has equal length sides forming a 90-degree corner. It's commonly used as a structural component in various construction and engineering applications due to its rigidity and load-bearing capacity. Square angles, like other angle iron profiles, come in various sizes, thicknesses, and materials to accommodate different load-bearing capacities and design requirements. The cross-sectional properties of the angle, such as the moment of inertia and section modulus, determine its performance under different loading conditions.
