Fencepoint is a trade supplier of 358 mesh fencing panels (Armex358) to contractors and construction companies across the UK. Also known as 358 prison mesh, 358 anti-climb mesh, 358 welded mesh, high-security mesh or weldmesh 358, the system takes its name from its tight aperture of 3" x ½" (76.2mm x 12.5mm). That aperture leaves no meaningful foothold or fingerhold, which is why 358 is one of the most specified high-security fencing systems in the UK.

Where 358 mesh fencing is used

Prisons and secure detention facilities
Schools, colleges and university campuses
Airports and transport infrastructure
Data centres and utility sites
Industrial and manufacturing sites
Public sector and government buildings

Why specify Armex358 anti-climb mesh

Anti-climb aperture. The 76.2mm x 12.5mm aperture gives no usable foothold or fingerhold, making Armex358 one of the most effective anti-climb fences available. Widely specified by architects and security consultants for high-risk perimeters.
Rigid, tamper-resistant panels. 4mm wire welded at every intersection makes a rigid panel that resists cutting, bending and impact. Anti-tamper fixings make unauthorised removal extremely difficult.
Takes security add-ons. Compatible with barbed wire arms, razor wire, electric fence outriggers and CCTV brackets, so it can be adapted to almost any security specification.
Low maintenance. Galvanised to BS EN ISO 1461:2022 and powder coated in Green (RAL 6005) or Black (RAL 9005) for long outdoor life.
Heights up to 3.0m. Stocked from 1.8m to 3.0m for different security levels and planning requirements.

358 Mesh Fencing Panels – Anti-Climb Prison Mesh FAQs

What is 358 prison mesh fencing?

358 prison mesh takes its name from its aperture: 3" x ½" (76.2mm x 12.5mm). The small aperture prevents footholds and fingerholds, making it extremely difficult to climb. Originally developed for prison perimeters, it is now specified for schools, airports, data centres and industrial sites.

Is 358 mesh the same as anti-climb mesh?

Yes. 358 mesh, prison mesh, anti-climb mesh and high-security mesh are all names for the same small-aperture welded panel. Armex358 is Fencepoint's 358 system.

What is the difference between 358 mesh and V mesh?

358 mesh is a high-security panel designed primarily to prevent climbing and cutting. V mesh (Armex45) is a lighter, more cost-effective profiled mesh for commercial boundaries where anti-climb is less critical.

Do you supply 358 mesh fencing nationwide?

Yes. Fencepoint supplies Armex358 panels, posts and fixings to contractors across the UK from stock, with deliveries scheduled to suit your programme.
