358 mesh
Welded mesh named after its 3in x 0.5in aperture and 8 gauge wire. The gaps are too small for fingers or a toe-hold, which is what makes it anti-climb.
Also called: 358 prison mesh, 358 fencing, anti climb mesh, prison mesh 358
358 mesh takes its name from its aperture in inches: 3 inches by 0.5 inches, on 8 gauge wire. In metric that is a 76.2mm by 12.7mm hole on 4mm steel.
Those dimensions are the entire security case. The hole is too narrow to get a toe or fingers into, so there is nothing to climb, and too narrow to get the jaws of a bolt cropper around a single wire, so cutting it means an angle grinder — loud, slow and visible. Both of the ways people normally get through mesh are closed off.
Flat beam and V beam
We stock it two ways. Flat beam panels have a plain face; V beam panels are pressed with V-shaped ribs that stiffen the panel, which matters most at 3m high. Security is identical — same aperture, same wire. Panels are 2.5m wide on both, narrower than the 3m used by lighter mesh systems.
Specified for prisons, substations, water treatment, data centres, rail and anywhere metal theft is a live risk.
