358 Fence: High Security Anti-Climb Welded Mesh with 76.2×12.7 mm Aperture
358 fence, also known as anti-climb welded mesh fence or prison mesh fence, is made of closely spaced horizontal and vertical wires forming a high-security barrier. It is widely used for prisons, military facilities, airports, and other areas requiring perimeter protection. 358 fence features 76.2×12.7 mm mesh openings and 4–5 mm welded wires for maximum security. Panels are 2.515–3.0 m wide and 1.8–3.0 m high, supported by galvanized or powder-coated posts. Anti-climb and anti-cut design makes it suitable for prisons, airports, and military sites.
