Rigid welded panel, roll mesh and 358 anti-climb mesh look similar on a drawing but perform very differently on site. Here is how to tell them apart and when each earns its place on a perimeter fence.
Pick by function, not price: a rigid welded panel is the default for permanent metal fencing and site security; roll mesh wins on speed and cost for temporary or low-risk perimeters; 358 anti-climb mesh is the answer where climbing resistance is mandatory. Standard heights run 0.6–3.0 m; perimeter security commonly uses 50×50 or 75×75 mm openings with 4–5 mm wire.
The shortest answer: choose a rigid welded panel for permanent site security, roll mesh for fast and economical enclosures, and 358 mesh where climbing resistance is non-negotiable.
A welded wire fence is any fence built from wires welded at the intersections into a stable grid. They share materials and coatings but differ in rigidity, aperture, install method and price — and those differences decide whether a fence actually protects the site or just marks the boundary. The form you choose is only the first of several linked decisions.
Same materials, very different behaviour on site.
| Form | Rigidity | Typical mesh opening | Typical height | Best use |
|---|---|---|---|---|
| Welded panel | Rigid, fixed plane | 50×50 – 200×200 mm | 0.6 – 3.0 m (custom) | Factory, school, perimeter security |
| Roll mesh | Flexible, stretches | 50×50 – 75×75 mm | 1.2 – 2.4 m typical | Temporary, low-risk, fast enclosures |
| 358 anti-climb | Rigid, dense grid | 76.2 × 12.7 mm | 2.0 – 3.0 m+ (custom) | High-security, prisons, utilities |
Standard fence height ranges 0.6–3.0 m with panel widths typically 2.0–3.0 m; sports venues run taller at 3.0–6.0 m. Perimeter security commonly specifies 50×50 or 75×75 mm welded mesh with 4–5 mm wire.
The default for permanent perimeter security.
Panels arrive pre-welded to a flat plane and clamp or bolt to posts, so the face stays dimensionally stable under impact and weather. That rigidity is why welded wire fence panels dominate factory, warehouse, school and utility perimeters. A 50×50 mm or 75×75 mm opening with 4–5 mm wire gives clear visibility for CCTV while blocking hand and foot holds.
Because posts and rails are matched to height, taller fences use thicker-wall sections. Finish with hot-dip galvanizing to EN ISO 1461, or a galvanized-plus-powder duplex coat where colour and branding matter. See the Custom Metal Fencing product page for supply envelope and lead times.
Fast, economical, flexible — but not rigid.
Roll mesh is supplied coiled and stretched between line posts with tension and brace bands. It goes up quickly and cheaply, which is why it suits construction sites, temporary enclosures and low-risk boundaries. The trade-off is real: a rolled fence deflects under load and offers almost no climbing resistance, and coatings follow the same reference performance rules as ASTM F668 / F900 for zinc-coated fabric.
Use roll mesh where the perimeter is temporary or the threat is casual; for anything permanent, a welded panel or 358 system is the safer specification.
The climbing-resistant option when the perimeter is the last line.
358 mesh uses a 76.2 × 12.7 mm aperture with 4 mm wire — too small for fingers and too tight for bolt-cutters to bite. It is the recognised security fencing standard for prisons, utilities and data centres. It mounts on the same clamped post line as a welded panel, so it drops into an existing perimeter with minimal redesign. We cover it in depth in the 358 anti-climb fencing guide.
Four questions before you order.
Start with the threat: casual boundary or determined intruder? Match height to the risk — 1.2–2.4 m for general sites, 3.0 m+ for high-security — then set the opening. Pick the coating by environment: hot-dip galvanizing (EN ISO 1461 / ASTM A123) for inland outdoor, duplex for coastal or branded frontages, and confirm post wall thickness scales with height.
For a permanent factory perimeter, a rigid welded panel fence is usually the strongest choice. Panels arrive pre-welded to a flat plane, mount to clamped posts and resist both impact and deformation better than roll mesh. Specify 50×50 mm or 75×75 mm openings with 4–5 mm wire for perimeter security, and finish with hot-dip galvanizing to EN ISO 1461 for outdoor life. If climbing resistance is a concern, step up to 358 anti-climb mesh on the same post line. Roll mesh is better reserved for temporary or budget enclosures where rigid security is not the priority.
Roll mesh is supplied coiled and installed by stretching between line posts — fast, economical and flexible, but it deflects under load and offers little climbing resistance. A welded panel fence is delivered as rigid sheets, bolted or clamped to posts, giving a flat, dimensionally stable face that holds its line under impact. The trade-off is cost and install time: roll is cheaper and quicker to erect; panels cost more but deliver a permanent, tamper-resistant perimeter. Perimeter security applications on the Zhaobang specifications page typically call for welded mesh rather than roll.
For perimeter security, 50×50 mm or 75×75 mm welded mesh with 4–5 mm wire is the common starting point — fine enough to block hand and foot holds yet open enough for clear site visibility and CCTV. Standard mesh openings run 50×50 mm to 200×200 mm, and panel widths are typically 2.0–3.0 m. Taller or higher-risk sites can drop to 358 mesh (76.2×12.7 mm) where anti-climb performance outweighs cost. Match the opening to the threat, not to a catalogue default, and confirm post size scales with the chosen height.
Posts and coatings can be common across types, but the details differ. Line and terminal posts are sized to fence height — thicker-wall sections for taller fences — and the same hot-dip galvanizing (EN ISO 1461 / ASTM A123) or duplex (galvanized plus powder) finish applies to any of the three. Panel and 358 systems use clamp brackets; roll uses stretched tension bands and brace bands. Because Zhaobang manufactures to drawing, posts, rails and panels are matched per project rather than taken from a fixed catalogue, so the coating and post structure stay consistent even when the mesh form changes between zones.
