358 Security Fence:

358 Security Fence are extremely difficult to penetrate, with the small mesh aperture being effectively finger proof, and extremely difficult to attack using conventional hand tools.'358' comes from its measurements 3" x 0.5" x 8 gauge which equates to approx. 76.2mm x 12.7mm x 4mm in metric.
358 High Security fencing system manufactured from hard drawn wire and electro-resistance welded at every intersection.
Mesh Pattern: 76.2mm (3") x 12.7mm (0.5") resistance welded at each intersection
Horizontal Wires: 4mm diameter at 12.7mm centres
Vertical Wires: 4mm diameter at 76.2mm centres.
It is also very difficult and time consuming to attempt to pass items from the protected area through the fencing, and for this reason alone makes the protection of valuable wire and cable a viable proposition.
Features:
Anti-climb: More small openings,no toe or finger holds.
Anti-cut: Robust wire and welded joints make cutting very difficult.
Better Visiblity: Flat,two-dimensional profile,easier to see through than chain link.

3510 Security Fencing
3510 Security Fencing has many of the attributes of 358 Security Fencing and the main strength is its lighter. Using 3mm wire instead of 4mm allows even better visibility allowing a wider variety of applications.It's lighter and cheaper so it's ideal for commercial applications.
Advantages: The aperture is 73.2mm horizontal x 9.7mm vertical and makes 3510 Security Fencing extremely difficult to penetrate using conventional hand tools, thus providing a high delay factor.
It is also very difficult and time consuming to attempt to pass items from the protected area through the fencing, and for this reason alone makes the protection of valuable wire and cable a viable proposition.
Using 3mm diameter wire with close apertures, makes 3510 hard to climb and with so many wires ensures it is difficult to cut through. 3510 like its high security cousin 358 has many applications, particularly where maximum to high security is not required. Coated in bezinal (95% zinc and 5% aluminium) for long life protection. Weld strength is minimum of 75% to steel strength guaranteed on every weld.
