D-Fence Duplo

Twin Wire Welded Mesh Fencing System

D-FENCE DUPLO Twin Wire Welded Mesh Fencing System is a premium high-strength perimeter security fencing solution specifically engineered for commercial, industrial, institutional, and critical infrastructure applications requiring enhanced rigidity, durability, and visual appeal. Designed for the American market, this advanced twin wire mesh fence combines superior structural stability with modern architectural aesthetics, making it an ideal alternative to traditional chain link and standard welded mesh fencing.

Built with a distinctive twin wire welded mesh structure, D-FENCE DUPLO utilizes heavy-duty 3-1/2 gauge (0.235") twin horizontal wires seamlessly welded to 5-1/2 gauge (0.199") vertical wires, creating exceptionally rigid fence panels that deliver unmatched strength and perimeter demarcation. The thick wire construction eliminates the need for V-bends, allowing for a clean, flat installation without waviness while maintaining maximum panel integrity.

With a 2" x 8" mesh size, tensile strength of 80–110 Kpsi, panel heights ranging from 4 feet to 15 feet, and widths up to 10½ feet, D-FENCE DUPLO provides superior perimeter protection for facilities such as data centers, power utilities, transportation hubs, schools, warehouses, industrial plants, government facilities, military installations, and secure commercial campuses.

Its modular design supports seamless directional changes, customizable decorative arch tops, smart fence integration capabilities, and multiple color options including green, red, yellow, and white—allowing property owners to balance security with architectural presentation.

Manufactured with powder-coated galvanized steel and protected by a 15-Year Product Warranty, D-FENCE DUPLO delivers exceptional corrosion resistance, low maintenance requirements, and long-term perimeter performance for high-demand environments where both security and aesthetics matter.

D-FENCE DUPLO is designed for facilities that demand more than standard perimeter fencing. It is a high-performance twin wire welded mesh system built to deliver superior strength, exceptional rigidity, and a premium architectural finish that elevates the appearance of any secured property.

Its signature twin wire design creates a powerful demarcation system by combining thick horizontal wires with robust vertical members, resulting in one of the strongest welded mesh fence solutions available.
