What Are the Dimensions of 358 Mesh Fence, and Does It Meet Australian Government Standards?

The name 358 mesh fence itself refers to its configuration: 3″ × 0.5″ × 8 gauge, or 75 mm × 12.5 mm × 4 mm. These dimensions ensure the ultimate protection for securing Sydney’s government and commercial structures.

With its sophisticated measures, anti-climb mesh installations like 358 Mesh Fence secure the critical infrastructure with ease. Let us explore this robust perimeter security solution from P&C Fencing.

Why is 358 Mesh Fence Preferred by NSW Government bodies?

Every physical security breach starts at the property perimeter. Here, a fence that’s specifically engineered for reliability, durability and robust security, is the most effective solution. 

Transport NSW utilise this fence type for rail corridors and train stabling yards. The Department of Defence utilise this fence on numerous facilities, all of which are 24-hour facilities.

1. Understanding the 358 Mesh Specification

The term “358 mesh” refers to its dimensions:

• “3–5–8” means:
  • 3″ horizontal pitch (75 mm) between each vertical wire
  • 5⁄8″ vertical spacing (13 mm) between each horizontal wire
  • 8-gauge wire (4 mm) diameter for horizontal wires

Together, these dimensions are why industry experts also call it “358 anti-climb mesh.” The tiny 13 mm gap prevents anyone from getting leverage for a foot, hand or tool, while the 75 mm span between vertical wires maintains excellent visibility and airflow.

This configuration of 358 Mesh helps to:

• Eliminate finger-grip and toeholds (anti-climb)
• Prevent insertion of cutting tools or contraband (anti-cut)
• Provide excellent visibility for surveillance systems and on-ground patrols

To fortify these features, it is important to source high‑quality zinc-aluminium or hot‑dip galvanised coated steel mesh that fully complies with AS/NZS 4534‑2006 coating standards.

2. Customisation-friendly Panels Fit Your Site Requirements

Commercial and Government sites often require specific heights, therefore, it is imperative to know the options and the specific range which 358 mesh provides. the dimensions of 358 mesh are as follows:

358 Mesh Panel Dimensions	General Range	Details
Height	2400 mm, 2700 mm, 3000 mm	Standard heights; custom options available
Width	2400 mm	Typical; can be joined for extended coverage
Wire Ø	4 mm (standard)	Heavy-duty fit for active deterrence
Aperture	75 × 13 mm	Precision-mesh to deter climbing and cutting by intruders

P&C Fencing’s design flexibility means that in addition to your fencing needs, whether your project needs a 358-mesh, sliding, swing, cantilever or pedestrian gate; customisation is readily available to you.

3. The Powdered Coatings are Suitable for Australia

We all know that Sydney’s climate can be tough on steel because of salt spray on the coast, harsh sun and occasional inland humidity. To protect your investment, a 358 mesh posts and rails receive specialised treatment that includes:

1. Hot-dip galvanising to Australian Standard AS/NZS 4534. This bath of molten zinc alloys bonds to each wire, offering robust corrosion resistance.
2. Optional powder-coat finish in government-approved hues, adding a colourful protective shell against scratches and harsh chemicals.
3. Steel posts, rails and brackets manufactured to AS 3679.1 (Grade 250) and finished to AS 4680 for enhanced durability 

These measures ensure that even under Sydney’s coastal humidity or challenging conditions, the integrity of your 358-mesh fencing remains uncompromised for decades. You can also expect it to be safe from mid-life rust-remediation costs.

4. Welding & Strength You Can Count On

Each intersection in a Fencing’s panel is resistance-welded under strict factory controls with us. This process:

• Bonds the mesh wires so securely that pulling or prying them apart would take extraordinary and specialised efforts.
• Meets industry welding standards, giving you tangible proof of its impeccable performance. Every intersection in our 358 mesh fence panels is resistance-welded to:
  • EN 10223-4 (weld integrity)
  • AS 2423-2006 (general welded mesh performance) 

A fencing contractor’s in-house fabrication facility also maintains regular internal audits, rigorous testing and QC approval. To you, that translates into panels that stay straight strong under loads and won’t deform if someone tries to deform them.

Does a 358 Fence Offer Any Towards Real-World Benefits?

While dimensions and coatings indeed provide the technical backbone, it’s the broader features of our 358-mesh fence that truly deliver:

• Surveillance-friendly: The profile of this mesh maintains sightlines for CCTV, lighting and patrolling. It means no blind spots for security cameras.
• Top-fix deterrents: From croc-tops to barbed wire or razor tape, specified per Government risk-assessment.
• Hostile Vehicle Mitigation (HVM): World-class crash-rated bollards and gates can be integrated with 358 mesh for ultimate security. This is most common for data centres and embassies.
• Logistics & Installation: Third-party accreditation with ISO 9001, 45001 and 14001 enforces qualified crews, WHS-compliant procedures, and NSW Government APIC accreditation compliance. This all ensures that work proceeds smoothly, even in live rail corridors or critical infrastructure zones. You can expect on-time delivery without compromising safety or budget.

How Versatile and Adaptive are the 358 Mesh Fences?

Our high-security gates are made with the same 358 mesh material to ensure consistency across a project. The most common configurations are:

• Swing gates for pedestrian and vehicle access
• Sliding gates in track sliding, cantilever and telescopic configurations
• Automated or manual operation, interfaced with any control system

Because gates share the same mesh profile, your finished boundary looks seamless. It also carries the same structural warranty as the rest of the fence. All these features come together and make 358 mesh fencing dependable solutions. 

Everything is customisable with this level of high-security product; height, fixing detail, fence top upgrades and powder-coat colour.
