Structural materials such as angles, channels, and beams are essential components in construction and engineering, providing support and stability to structures. Angles, typically L-shaped, are used for framing, bracing, and reinforcement, offering versatility in joining and load transfer. Channels, with a U-shaped cross-section, are employed for framing, support, and track applications, providing strength along their length. Beams, which come in various shapes like I-beams, H-beams, and T-beams, serve as primary load-bearing elements that transfer loads from floors, roofs, and walls to columns and foundations. These materials are manufactured from various alloys, including steel and aluminum, chosen based on strength, durability, and environmental considerations. Proper selection and utilization of angles, channels, and beams are crucial for ensuring the safety, stability, and longevity of structures.
