358 security fence uses a close 76.2 × 12.7 mm welded aperture with 4 mm wire.
Low-carbon steel wire can be hot-dip galvanized or plastic coated. Green and black are regular coating colors, with others available by confirmation.
Description
A 358 security fence is a close-mesh perimeter panel used where ordinary boundary control is not enough. The 76.2 × 12.7 mm opening is small, so there is little room for fingers, shoes, or common hand tools to pass through. At the same time, the welded grid remains open enough for routine observation through the fence. The panel is usually combined with substantial posts and protected fixings. Gates, corners, and any top security treatment should be considered as part of the same perimeter rather than added after the main mesh has been ordered. This close grid also makes the panel less visually dominant than a solid wall, which can be useful where security staff still need sight lines across the perimeter. The fence remains a physical barrier rather than a privacy screen.

Features
The small opening is the main reason 358 security fence is used at controlled sites. It reduces easy hand and footholds while keeping the boundary visible. Fixings and posts still matter: a close-mesh panel cannot compensate for weak connections or poorly planned gate areas.

FAQ
Q: Why is it called 358?
A: The name 358 security fence comes from the traditional imperial description of the mesh: 3 × 0.5 inches with 8-gauge wire, represented here by the metric 76.2 × 12.7 × 4 mm format.
Q: Can common cutters easily reach through the mesh?
A: The narrow opening limits tool access compared with wider mesh, although the overall security level also depends on posts, fixings, gates, and site design.
Q: Which colors are regular?
A: Green and black are listed as regular colors; other colors can be confirmed for the project.
