High-Security Double Loop Wire Fencing PVC-Coated for Airport Perimeter Protection
Product Description-Double Loop Wire Fencing:
The Reliable Perimeter Protection for Multi-Scene Security
Double loop wire fencing, characterized by its unique "double-loop interlocking structure", integrates anti-climb performance, corrosion resistance, and durability. Made of high-quality Q235 low-carbon steel, it undergoes hot-dip galvanizing (zinc coating 600-800g/㎡) or PVC coating (0.8-1.2mm thickness) to resist harsh environments like farm humidity, airport outdoor exposure, and zoo animal scratches. With a Class B anti-climb grade (per EN 1522-5), it effectively prevents intruders from climbing even with tools, while the flexible mesh design absorbs impact—ideal for containing large animals in zoos or preventing livestock escape on farms.

Advantages:
Super Anti-Climb Performance:The double-loop interlocking structure has no obvious footholds, and Class B anti-climb grade (per EN 1522-5) prevents climbing with ladders or hooks.
Strong Corrosion Resistance:Hot-dip galvanized models have a zinc coating of 600-800g/㎡—SGS salt spray tests show no red rust after 1000 hours (equivalent to 15 years of outdoor use). PVC-coated models (0.8-1.2mm thickness) resist acid and alkali, suitable for humid farms in Southeast Asia.
Quick Installation:Pre-assembled panels (standard 2.5m/3m length) and matching accessories (posts, clamps) reduce on-site work.
Impact Resistance:The flexible double-loop structure absorbs impact force—tests show it can withstand 500N impact (equivalent to a 100kg animal collision) without deformation.
Production Process:
Raw Material Processing:Q235 low-carbon steel wires are drawn to specified diameters (2.5-4.0mm) and annealed to improve ductility, ensuring no breakage during bending.
Double-Loop Forming:Horizontal and vertical wires are woven into double-loop interlocking mesh by automatic looms, with mesh size precision controlled within ±1mm.
Surface Treatment:- Hot-dip galvanizing: Mesh is immersed in 450℃ molten zinc for 3-5 minutes, forming a 600-800g/㎡ zinc layer. - PVC coating: Galvanized mesh is electrostatically sprayed with PVC powder, then cured at 200℃ for 15 minutes to form a 0.8-1.2mm coating.
Panel Cutting & Assembly:Mesh is cut into standard panels (2.5m/3m length) and reinforced with edge wires; matching posts (galvanized/PVC-coated) and clamps are produced simultaneously.
Quality Inspection:Each batch undergoes wire diameter measurement, zinc coating thickness test (using a coating thickness gauge), and anti-climb performance simulation—only qualified products are packaged.
