What does 358 mean in anti-climb fencing?

The name refers to a nominal 3 inch by 0.5 inch mesh opening and an 8 gauge wire reference. In metric specifications, buyers commonly compare a 76.2 mm × 12.7 mm opening with 4.0 mm nominal wire, then confirm posts, fixings, gates and any required system test rating.

Why is 358 mesh used for security perimeter projects?

The narrow nominal opening limits hand- and footholds and keeps good visibility. A security rating applies only when the complete panel, post, fixing and gate system is assessed to the required standard.

What additional security extensions do you offer for high-risk zones?

We can supply Y-shaped or L-shaped extensions, concertina razor wire arms, barbed wire rows and brackets for electronic intrusion detection cables.

How do you prevent corrosion on dense 358 weld joints?

Welded joints are inspected, then panels are coated according to the selected galvanizing and powder system. Higher zinc and upgraded coating options are recommended for coastal or humid projects.

358 Anti-Climb Welded Mesh Fence

358 anti-climb mesh fencing is named after a nominal 3 inch x 0.5 inch mesh opening and 8 gauge wire reference. The narrow opening limits hand- and footholds, while RHS posts, flat bars, security bolts, gates and any required test rating must be confirmed for the complete project system.

Product overview

How to Specify 358 Anti-Climb Fence

Define the security objective first, then confirm 358 mesh as a panel, post, fixing, gate and topping system.

What it is

358 anti-climb fence commonly uses a nominal 76.2 mm × 12.7 mm aperture with 4.0 mm wire. The panel must be specified together with posts, fixings, gates, coating and any required security topping.

Common applications

Prisons and detention centers
Military and police facilities
Data centers and utilities
Airports and rail infrastructure

Details to confirm

Required security level or standard?
Height, total length and gates?
RHS post and flat bar or bolt fixing?
Topping and coating system?

For quotation comparison: Do not compare loose mesh with a security system: panel, posts, fixings and gates must use the same scope.
