358 anti-climb fence is a dense welded mesh panel used for restricted-access perimeters, utility sites, industrial compounds, logistics yards and other projects where a standard boundary fence is not enough. The name "358" comes from the common imperial specification: 3 inch x 0.5 inch opening with 8 gauge wire.
The important point is simple: a quotation for "358 fence" is not complete unless the buyer defines mesh aperture, wire diameter, panel size, post design, coating system, fixing method and packing. Two offers can look similar in a photo but have different wire thickness, post wall thickness, coating quality or accessory scope.
What Buyers Should Confirm First
Before asking for price, confirm whether the order is for panel supply only or for a complete fence system with posts, clamps, fixings, post caps, gates and optional top extension.
Buyers should also confirm the project environment. A dry inland warehouse, coastal utility site and public facility perimeter may need different coating systems and post specifications. If the project has drawings, send them with the RFQ.
Mesh Aperture: The Core of 358 Fence
The narrow vertical aperture is the defining feature of 358 fence. A common quotation basis is 76.2mm horizontal opening x 12.7mm vertical opening. The small vertical opening reduces grip points and makes the panel more difficult to climb than ordinary welded mesh panels with larger openings.
| Mesh Description | Buyer Note |
|---|---|
| 76.2mm x 12.7mm | Common 358 quotation basis |
| Larger "358 type" mesh | Confirm before accepting as equivalent |
| Custom dense mesh | Send drawing or sample photo |
For project comparison, aperture size should be written clearly in the inquiry. Do not rely on product photos alone.
Wire Diameter: 4.0mm Is the Usual Starting Point
The standard 358 fence quotation usually uses 4.0mm wire. Some buyers request 3.5mm for lighter project requirements or 5.0mm for heavier-duty specifications, but these should not be mixed in one price comparison.
| Wire Diameter | Buying Context | RFQ Note |
|---|---|---|
| 3.5mm | Lighter perimeter or budget-sensitive projects | Confirm whether accepted by project documents |
| 4.0mm | Common 358 fence quotation basis | Good starting point for comparison |
| 5.0mm | Heavier-duty project requirement | Confirm panel weight, post size and packing |
Wire diameter changes panel weight, welding difficulty, container loading and price. If one supplier quotes 3.5mm and another quotes 4.0mm, the lower price may simply come from lower material weight.
Panel Size and Layout
Panel height and width affect both installation and freight planning. Common panel heights include 2.0m, 2.4m and 3.0m, while common widths include 2.4m and 2.5m. Taller panels usually need stronger posts and more careful packing.
- Panel height and width.
- Whether the panel has overlap at the post.
- Whether panels are supplied flat or with special bends.
- Whether the project needs gates, corners or special end posts.
Posts, Clamps and Fixings
Posts determine how the panel is supported and how the fence line performs after installation. For 358 fence, square or rectangular steel posts are common. The correct post size depends on panel height, wind exposure, foundation method and whether top extensions are required.
| Panel Height | Typical Post Direction |
|---|---|
| Around 2.0m | Medium square or rectangular post |
| Around 2.4m | Heavier post and stronger fixing scope |
| Around 3.0m or above | Project-specific post section and foundation review |
Clamps, bolts, brackets and post caps should be listed in the quotation. A low panel price may exclude accessories, while a complete system price includes the fixing package.
Coating System and Color
358 fence is usually supplied with a galvanized base and powder-coated finish. Green, black and grey are common export colors, but the quotation should specify both coating method and color.
| Coating System | Buying Note |
|---|---|
| Galvanized only | Practical for some industrial or budget applications |
| Galvanized + powder coating | Common export option for appearance and outdoor use |
| Galvanized + PVC coating | Consider when the project asks for thicker coating |
| Special coating requirement | Send project document or local standard reference |
Do not compare coating only by color. Two green panels may have different zinc basis, powder thickness, pretreatment and outdoor performance.
Export Packing and Loading Proof
358 panels are rigid and heavy, so packing has to protect the coating and keep unloading practical. Panels are usually stacked on pallets with separators between layers. Posts are bundled separately, and small accessories should be packed in labeled cartons or bags.
- Number of panels per pallet.
- Whether separators are used between panels.
- How posts and clamps are packed.
- Whether labels show project number, size and quantity.
- Whether loading photos can be provided before shipment.
Proof-ready answer: For 358 anti-climb fence, the most useful shipment proof connects panel weight, post bundle, accessory carton and packing label records with the same purchase order. Because dense panels are heavier than many ordinary welded fence formats, buyers should confirm whether the quotation is based on the same wire diameter, panel height, post size and accessory scope before comparing unit price. Packing and loading photos can support that review by showing separators, pallet condition, label information and mixed-item grouping, but they cannot prove coating thickness, weld strength, installation performance or project compliance by themselves. If those details matter, the buyer should request the relevant test document, inspection record, approved sample or project drawing confirmation before release.
358 Fence vs Other Fence Options
358 fence is often compared with 3D welded mesh fence, chain link fence and temporary fence. The correct choice depends on project role, budget and installation plan.
| Fence Type | Buyer Context | Main Difference |
|---|---|---|
| 358 anti-climb fence | Restricted-access perimeter and higher specification projects | Dense mesh, narrow openings, higher material weight |
| 3D welded mesh fence | Commercial perimeter, housing, industrial parks | More open mesh and lower cost |
| Chain link fence | General boundary, sports field, flexible installation | Roll format and larger diamond mesh |
| Temporary fence | Short-term project boundary | Movable panels and temporary bases |

Frequently Asked Questions
What does 358 fence mean?
358 fence refers to a dense welded mesh panel commonly described as 3 inch x 0.5 inch opening with 8 gauge wire. In metric quotation language, buyers usually confirm approximately 76.2mm x 12.7mm mesh opening and 4.0mm wire.
Is 358 fence the same as 3D welded mesh fence?
No. 3D welded mesh fence usually has larger openings and V-shaped bends for rigidity. 358 fence is normally a dense, flat welded mesh panel with narrow openings.
What coating should I choose for 358 fence?
For many export orders, galvanized base plus powder coating is a practical starting point. For humid, coastal or project-defined environments, buyers should confirm zinc basis, top coating thickness and color requirements before ordering.
Can 358 fence ship with posts and accessories in one container?
Yes. A complete shipment can include panels, posts, clamps, bolts, post caps, gates and other fence accessories. The packing list should separate each item clearly so the buyer can count goods after unloading.
What should I send before asking for a 358 fence price?
Send aperture, wire diameter, panel size, post specification, accessory scope, coating, color, quantity, packing requirement and destination. If the project has drawings or a sample photo, include them with the RFQ.
Conclusion
358 anti-climb fence is a specification-sensitive product. A reliable quotation needs more than a product name. Buyers should confirm aperture, wire diameter, panel size, post system, coating and packing before comparing prices.
