Anti-climb mesh is close-spaced welded steel mesh designed to make climbing more difficult and restrict access for cutting tools. It is used as part of perimeter fencing systems where security, visibility and controlled access matter.

What is anti-climb fencing?
An anti-climb fence combines closely spaced mesh with compatible posts, fixings and gates. The small openings limit opportunities for hand and foot holds, while the welded panel provides a rigid barrier. Mesh selection is one part of the design: fence height, ground clearance, gate details and nearby climbable objects also affect performance.
What is 358 security mesh?
358 mesh is a type of welded security mesh commonly used for anti-climb fencing. The name comes from the traditional imperial specification of approximately 3 inches by half an inch with 8-gauge wire.
The current Promax™ 358 component tables specify a nominal 75 × 13 mm pitch with 4 mm wire for standard panels. Pitch describes wire spacing and is different from the clear opening between wires. Use the current product tables and project drawings when specifying panel dimensions, wire sizes and post centres.

Why use anti-climb mesh?
- Climbing resistance: close wire spacing reduces usable hand and foot holds.
- Restricted tool access: small openings make it harder to position cutting tools.
- Visibility: the mesh supports sight lines through the perimeter for observation and surveillance.
- System options: compatible posts, gates, fixings and toppings allow the fence to be configured for the site.
No fence can guarantee that climbing, intrusion or injury will never occur. The complete system should be selected for the site's security requirements and assessed alongside access control, surveillance and ongoing maintenance.
Where is anti-climb mesh used?
Promax™ 358 fencing is used for high-security perimeters including correctional facilities, defence sites, data centres, power utilities and rail infrastructure. Suitability depends on the project brief and the specified fence system.
Choosing an anti-climb fence system
Before ordering, confirm:
- Required fence height, site levels and total fence length.
- Panel dimensions, post centres, ground conditions and structural loads.
- Promax™ T-post or UC-post requirements, with post-and-rail or rail-less configurations where appropriate.
- Gate openings, access arrangements, fixings and any security toppings.
- Coating or finish suited to the environment, including LifeMax zinc/aluminium alloy coated wire and available powder coating options.
- Project-specific standards, engineering documentation and installation requirements.
