Angle

Definition

An angle is a structural steel section that resembles an "L" in cross-section, consisting of two perpendicular legs that form a right angle.

Purpose

The primary purpose of an angle is to provide structural support and reinforcement in construction and engineering applications. Its L-shaped cross-section offers high strength and stability, making it ideal for use in frameworks, bracing, and other structural elements. Angles are used to distribute loads evenly and resist bending, twisting, and other forces, enhancing the overall integrity and durability of structures.

Examples of Use

1. Building Frames: Angles are commonly used in the construction of building frames, providing support for floors, walls, and roofs. They help in creating rigid and stable connections between different structural components.
2. Bracing: In structural engineering, angles are used as bracing elements to reinforce and stabilize frameworks, preventing lateral movement and increasing the structure's resistance to forces such as wind and seismic activity.
3. Shelving and Storage: Angles are used to construct shelving units and storage racks, providing strong and stable support for holding heavy items.
4. Bridge Construction: In bridge construction, angles are used in trusses and other load-bearing components to provide the necessary strength and stability for supporting traffic loads.
5. Machinery and Equipment: Angles are used in the fabrication of frames and supports for machinery and equipment, ensuring they remain securely in place during operation.
