358 Anti-Climb Security Fence | ASTM F2656-20 Rated

358 security mesh is the welded wire fabric that forms the core of high-security fencing systems, characterized by its distinctive 76.2mm x 12.7mm aperture dimensions and 4.0mm wire diameter. Hebei Maifa Metal Products Co.,Ltd. manufactures 358 security mesh using high-tensile carbon steel wire drawn to precise gauge tolerances, then resistance-welded at every intersection to create a rigid, non-sagging panel. The 358 security mesh designation originates from the approximate imperial measurements: 3-inch horizontal aperture, 0.5-inch vertical aperture, and 8-gauge wire. This combination creates a barrier where the small vertical aperture prevents finger or toe insertion, while the 4.0mm wire diameter and welded construction resist cutting by bolt cutters or wire cutters. Our 358 security mesh is produced in panel widths of 2.0m, 2.2m, 2.5m, and 3.0m, with panel heights ranging from 1.0m to 4.0m. Surface treatment options include hot-dip galvanizing after welding, which applies a protective zinc coating to the entire mesh including all weld points, and Galfan coating (95% zinc / 5% aluminum alloy) for extended corrosion protection. For applications requiring additional aesthetics or color coding, we offer polyester powder coating over galvanizing in all RAL colors. Applications for 358 security mesh include prisons and detention centers, military bases, embassy perimeters, data center security zones, airport airside boundaries, power plants, and border control facilities.
