358 fencing—also known as “358 stainless steel fencing” or “358 reinforced steel fencing”—is a type of protective barrier constructed from high-strength steel materials. This 358 fence panel is widely utilized for security protection, industrial partitioning, railway and highway safety, prisons, airports, warehouses, and other locations requiring extremely high levels of security.

3″: Refers to the vertical spacing of the mesh openings, approximately 76.2 mm.
0.5″: Refers to the horizontal spacing of the mesh openings, approximately 12.7 mm.
8 Gauge: Refers to the diameter of the steel wire, typically 4 mm.

The 358 mesh fencing produced by Sinotop offers exceptional, high-level security protection. Due to the extremely small aperture of the mesh, it is impossible for human fingers or toes to be inserted into the openings, nor can one find sufficient footholds to facilitate climbing.

The steel wires are of a substantial diameter (4 mm) and are arranged in a dense mesh pattern, making it extremely difficult for standard wire cutters or small cutting tools to effectively sever them. Our 358 fencing is fabricated by welding high-quality low-carbon steel wires, resulting in a robust structure with excellent structural integrity. When paired with a matching 358 Fence Gate, the overall security performance is further enhanced.

Our 358 fence panel undergoes surface treatments such as hot-dip galvanizing, followed by powder-coating or PVC-coating. These treatments endow the fencing with superior resistance to corrosion and rust, ensuring a long service life. Additionally, as a professional security fence manufacturer, we offer customization services, allowing clients to select specific colors to suit the requirements of their surrounding environment.

Advantages of our 358 Mesh Fencing

Military-Grade Security

3″×0.5″(76.2mm×12.7mm) ultra-dense welded mesh opening deters climbing, cutting, and tool penetration, exceeding ASTM/BS EN standards for high-risk facilities.

360° Surveillance Ready

Optimal visibility maintains clear sightlines for CCTV monitoring and security patrols while preventing visual obstruction.

Uncompromising Durability

8-gauge (4mm) galvanized steel construction with optional powder coating resists corrosion, impact (up to 40J tested), and extreme weather conditions.

Tool-Resistant Design

Proprietary panel welding technology thwarts bolt cutters, angle grinders, and manual breaching attempts (tested to LPS 1175 SR3).

358 Fence Panels Production Process

Galvanized Wire

Use galvanized steel wire that meets the standards to ensure that the material is of high quality and meets the design requirements.

Straighten and Cut

Straighten the galvanized steel wire, remove the bends and deformations, and then cut it according to size to prepare for the next step of production.

Wire Mesh Welding

Weld the cut steel wire horizontally and vertically according to the designed grid to form a mesh structure. Ensure that the welds are firm and the mesh is flat.

Panel Welding

Fix the prepared wire mesh to the frame of the door and weld the side or frame to ensure that the structure is firm and beautiful.

Surface Cleaning

Remove the grease, impurities during the welding process through chemical cleaning or mechanical cleaning to prepare for subsequent protective treatment.

Zinc Painting

The entire product body forms a uniform and compact zinc layer to enhance corrosion resistance.

Powder Coating

Powder Coating provides a rich color selection for the product, while increasing the anti-corrosion and aesthetic effects.

Quality Control

Check the welding quality, uniformity of the galvanized layer, and coating performance to meet the quality requirements.

Packaging

Use protective materials for packaging, prepare for shipment, and ensure that the product is intact during transportation.

358 Mesh Fence Application Scenarios

It is ideally suited to any application that demands the toughest protective measures, including:

Prisons
Utilities
Mesh industrial fencing
Police facilities
School security fencing
Commercial fencing
Ports and airports

How to Install 358 Mesh Fence?

Determine the position of the posts: Based on the previous markings, determine the exact position of each post.
Drilling: Place the post at the marked position, use the holes on the flange as a template, and mark the drilling position on the ground.
Fix the post: Align the flange of the post with the position of the expansion bolt, pass the bolt through the hole on the flange. Tighten the nut to fix the post on the ground.
Install the fence mesh: Use connecting parts (such as clips, bolts, nuts, etc.) to connect the mesh to the post. Ensure that the mesh is tightly connected to the post without any looseness.
Check and adjust: Check whether the overall structure of the fence is firm and stable.

358 Security Fence Packaging

Our 358 high-security fence is fully sealed with plastic film and transported on wooden pallets, which effectively isolates moisture and corrosive media.
Each packaging unit is fixed to the pallet with high-strength special tape, so it can ensure zero displacement risk during transportation.
Anti-collision sponge pads are installed at the bottom of the pallet, and metal edge guards (1.5mm galvanized steel plate) at the four corners can withstand multiple loading and unloading impacts by forklifts.
