What does 358 mean?

358 anti-climb fence usually refers to a welded mesh panel with a small rectangular opening around 76.2 x 12.7 mm. This opening makes it difficult to get a foothold or insert common cutting tools.

Confirm wire diameter and panel height

Common wire diameters include 4.0 mm and 5.0 mm. Panel heights such as 1.8 m, 2.0 m, 2.4 m and 3.0 m are used depending on site security level. Higher panels need matching post strength and foundation design.

Specification tip For RFQ, send mesh opening, wire diameter, panel height, panel width, post type, coating, color and gate quantity.

Posts and fixing method matter

The post is not a small accessory. Square posts, I posts and custom high-security posts create different installation details and cost. Confirm post spacing, clamps and anti-tamper bolts before production.

Where is 358 fence used?

358 anti-climb fence is often used for airports, utilities, schools, warehouses, industrial sites and other boundaries that need higher security than ordinary welded mesh fence.
