High Security Fence

358 Anti-Climb Welded Mesh Fence

Narrow-aperture welded mesh with project-specific posts, fixings, coating and security options.

Custom manufacturing: dimensions, structure, material, coating, accessories, labels and packing are confirmed before production.

Narrow Aperture: The nominal 76.2mm x 12.7mm opening limits hand- and footholds. Security performance depends on the complete tested system.
Wire and Weld Specification: Confirm wire grade, nominal diameter, weld quality and any required test rating in the approved specification.
Complete System Selection: Post section, flat bars, bolts, gates, top extensions and coating are selected for the project rather than assumed from the panel name.

Buyer decision snapshot

What is 358 Anti-Climb Fence?

A common reference configuration uses 76.2 x 12.7mm mesh and 4.0mm wire. Panel height, RHS posts, flat bars, bolts, coating and test requirements are project-specific.

358 anti-climb fence 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 posts, fixings, gates and any required test rating must be confirmed for the complete project system.

QC, packing and shipment readiness

What Is Confirmed Before Mass Production

These checks reduce component mismatch, wrong material or finish, missing accessories and packing damage.

Dimension & Tolerance Check

358 Anti-Climb Fence orders are checked against confirmed wire or steel size (4.0mm nominal; tolerance confirmed in the approved specification), opening or spacing (76.2mm x 12.7mm), target dimensions and tolerances before production release.

Surface Treatment Review

Material grade, coating or finish is confirmed as Galvanized wire + architectural polyester powder coating, with the service environment reviewed before mass production.

Component & Accessory Matching

The main product is matched with RHS post section selected by fence height, loads and approved drawing, joining parts and project-specific accessories to reduce missing-part risk.

Export Packing Plan

The main product and accessories are grouped for container loading with buffers, wrapping and a clear pallet layout to reduce deformation and surface damage.

Technical FAQ and alternatives

Buyer Questions Before Quotation

Resolve the main specification questions, then compare nearby systems only if the project requirements differ.

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 76.2mm x 12.7mm opening with 4.0mm 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.
