HIGH-SECURITY FENCE - WELDED MESH: MATERIALS, COATING, POSTS, AND INSTALLATION

Metech Welded Mesh Inc manufactures and exports high-security welded mesh fencing. Our high-security steel welded mesh panels are made with close small openings and strong thick wire, suitable for governmental facilities, transportation hubs, residential communities and various premises. Coils of clipped razor tape with medium barbs are commonly used in HSF system, with one row on top and one row on the bottom of the fence panels.

Below, we introduce in detail materials for construction of high security fence system.

High-Security Welded Mesh Fencing Standard

Materials and construction of High-Security Fencing – Welded Mesh (HSF – WM) are in compliant with the following referenced standards:

• EN 10016-2: This standard outlines specifications for non-alloy steel rods suitable for drawing and/or cold rolling processes.
• EN 10218-2: This standard outlines the dimensions and tolerances for steel wire and related products.
• EN 10223-7: This standard outlines requirements for steel wire and wire products used in fences, with a particular focus on welded steel wire panels.
• EN 10244-2: This standard outlines non-ferrous metallic coatings on steel wire, specifically zinc or zinc alloy coatings.
• EN 10245-1: This standard outlines general rules for steel wire and wire products with organic coatings.

High Security Fence – Welded Mesh (HSF – WM) Panels

HSF – WM fencing panels are made of galvanized steel wires welded then coated with polyester at height of 2.42 meters. HSF Weld mesh panels feature round horizontal wires and thicker round vertical wires. Horizontal wires are doubled at every 1210 mm, a double wire at the bottom and a double wire at the top, as illustrated in Fig.

Fence Panel
Fence panels are galvanized and coated with polyester.

• Height of the Panel: Overall height 2416 + 3 mm.
• Width of the Panel: Overall width, not including overhangs, 2292 + 3 mm.

Mesh Dimensions and Tolerances
Nominal mesh size is determined by the distance between the centers of two adjacent wires:

• Distance between vertical wires: 76.2 + 2 mm
• Distance between horizontal wires: 12.7 + 1 mm

Wire Diameter

• Diameter of the horizontal wires: 4.00 + 0.08 mm
• Diameter of the vertical wires: 6.00 + 0.09 mm

Tensile Strength

• Horizontal wires: 600 to 810 N/mm².
• Vertical wires: 400 to 550 N/mm².

Wire Rod

Chemical composition of wire rod:

• Carbon (C): <0.10%
• Silicon (Si): <0.30%
• Manganese (Mn): <0.60%
• Phosphorus (P): <0.035%
• Sulfur (S): <0.035%

Wire rod conforms to the European standard EN 10016-2 and is designated as C9D.
