Anti-intruder Fences in Chain Link and Welded Mesh

Chain Link and Welded Wire Anti-intruder Fences

Anti-intruder fence is designed for situations that requires a higher level of protection like factory, airport. We supply two types of anti-intruder fences: chain link fence and welded wire mesh fence. Despite of different workmanship, these two fence panels are both produced at least 2.4 m in height and compatible with barbed wire, razor barbed wire to prevent intruders from entering.

Chain Link Fence

Our anti-intruder chain link fence panel is made of mild steel wire with 40 mm or 50 mm mesh openings. The width of the mesh shall be 2.4 m, if it is not to be buried, or 2.7 m if it is to be buried. To make an anti-intruder fence, chain link mesh panels are joined by interweaving a spiral and restoring the knuckle or barb.

On account of chain link panels' specific workmanship, several types of wires is needed: line wire, stirrup wire and tying wire. Line wire is used to across the entire panel horizontally and linked together with posts at the ends. For 2.4 m height fence, 5 rows of line wires are necessary, the top row of wires shall be double and secured not more than 50 mm below the top of the chain link mesh. Stirrup wire is used for securing line wires to intermediate posts. Tying wire is used for securing mesh to line wires.

To fix our chain link fence panel, concrete, steel and wooden posts could all be used. We can only offer steel posts with well-suited holes but not wooden or concrete posts in consideration of transportation and costing. Posts to match 2.4 m height fence should be not less than 3.2 m. We can provide two types of posts: normal mesh fixed posts and heavy duty mesh fixed posts. Intermediate posts, straining posts and struts are supplied separately in our company.

Welded Wire Mesh Fence

Green PVC coated welded wire mesh panels are overlapped on the earth waiting for installation.

AIF-03: Anti-intruder fence made by welded wire mesh panels extended a small part on the top.

Anti-intruder welded wire mesh fence is made from zinc coated wire. The height of the welded mesh fence is 2.4 m, if it is not buried, or 2.7 m if it is buried.

If plastic coated mesh panel is used by combing two panels to reach a 2.4 m height, the panels could be 1500 mm and 1050 mm for 75 mm × 25 mm mesh or 1500 mm and 1000 mm for 50 mm × 50 mm mesh.

If plastic coated mesh panel is used by combing two panels to reach a 2.7 m height, the panels could be 1800 mm and 1050 mm for 75 mm × 25 mm mesh or 1800 mm and 1000 mm for 50 mm × 50 mm mesh. Because the panels shall be overlapped horizontally by a minimum of two complete meshes in consideration of a solid structure.

Barbed wire and razor barbed wire fixed to the top edge could be provided on request. Welded mesh fences have four line wires evenly spaced on the panel.
