Aperture, wire gauge, panel heights, post centres and finishes - the numbers you need to write or check a 358 mesh specification.
The name 358 is the specification. It describes an aperture of 3 inches by 0.5 inches in 8-gauge wire, which converts to 76.2mm x 12.7mm openings in 4mm diameter wire. Every other property follows from those three numbers: the opening is too narrow for a finger or a boot tip, and the wires sit close enough together that bolt cutter jaws cannot seat squarely on a single strand. We install it from industrial estates in Wetherill Park and Smithfield to school and childcare upgrades across the Hills District.
Standard panel heights are 2.1m, 2.4m and 3.0m in 2515mm widths, fixed to 60mm or 80mm SHS posts at 2.5m centres, with clamp bars and shear-nut fixings so panels cannot be unbolted from the outside. Finishes are hot-dip galvanised to AS/NZS 4680 as standard, with PVC or powder coat in black or green where appearance or coastal corrosion matters. To have this system surveyed, quoted and installed, see our security fencing Sydney hub. For the full range of climb-resistant systems, see our security fencing Sydney service, or our industrial fencing Sydney page for warehouse and depot perimeters.
Every install is completed by a licensed, insured crew carrying $20M public liability, and we have fenced across NSW since 2016. Whether you need a single secure boundary run or a staged perimeter across a whole site, we manage supply, delivery and installation end to end.

Common questions about 358 anti climb mesh fencing in Sydney NSW
358 anti climb mesh fencing is a high-security welded steel mesh with apertures of 76.2mm x 12.7mm, which measures 3 x 0.5 x 8 inches and gives the fence its 358 name. The tight mesh gives no foothold, so it cannot be climbed, and it is extremely difficult to cut with hand tools. It is the leading choice across Sydney for schools, substations, correctional facilities and critical infrastructure perimeters.
Supplied and installed, 358 anti climb mesh fencing in Sydney is priced per metre for standard 2.4m galvanised panels, and more for 3.0m heights or PVC-coated finishes. Pricing depends on height, coating, post spacing and site access. We provide a firm written quote after a free Sydney site assessment.
A typical 358 anti climb mesh run of 30 to 60 metres is installed in one to three days once posts are set and concrete has cured. Larger industrial perimeters are staged over one to two weeks. We coordinate delivery of panels and posts to your Sydney site so the install stays on schedule.
