Expanded mesh is a durable and versatile metal sheet that has been cut and stretched to form a uniform pattern of diamond-shaped or hexagonal openings. It is strong, lightweight, and allows excellent airflow, light passage, and drainage while maintaining rigidity. Commonly used for fencing, security screens, walkways, machine guards, and building facades, expanded mesh provides both functionality and modern appearance. It is available in different materials such as mild steel, galvanized steel, aluminum, and stainless steel, making it suitable for indoor and outdoor applications.
