Why Do We Call It 358 Mesh?

Gryffin have been designing fence systems with 358 mesh for many years now and we have heard it called by a multitude of generic names; Secure-Mesh, Anti-Climb Mesh, Belgian Wire and 358 Mesh to name just a few.  Additionally there are the brand names for 358 mesh - our Securifor 358, Gryffin 358, Fortis 358 and all of our oppositions brand names for their product.  With all these different names floating around, one could be excused for wondering what do the numbers 358 actually mean?  Good Question -  The numbers 358 refer to the aperture and gauge of the wire in the old Imperial measurement.

For more information, please visit our website.

• The centre to centre measurements of our vertical wires is 76.2mm or 3 Inches
• The centre to centre measurement of our horizontal wires is 12.7mm or 0.5 Inches
• The 4mm wire used to create the mesh is known as Gauge 8

 

 Put it all together and you get 358, a tough, versatile, cut & climb resistant mesh that creates a smart physical barrier without impairing line of sight.  For a full range of fence styles, gates and fixings give us a call we are only too happy to help.

3D security fence enhanced its appearance with pressed horizontal 'V' shaped beams.

3D security fence is similar to 358 mesh fence, and they are both made from 4.0 mm wire in 12.7 × 76.2 mm mesh pattern. But 3D security fence enhanced its appearance with pressed horizontal 'V' shaped beams. It is a unique barrier solution which combines a high level of safety and aesthetic appearance. Usually, 3D security fencing is recommended for schools, recreational areas, hospitals, railways, port, airport, warehouses and industrial facilities or commercial.
