Varjeni mrežni sistem proti plezanju (Poznan tudi kot zaporniška mreža oz 358 mreža) se večinoma uporablja v ograjnih sistemih, ki so zasnovani tako, da zagotovijo maksimalno zaščito perimetra na lokaciji brez oviranja vidljivosti (kar je pomembno za človeško patruljiranje ali videonadzor). This style of mesh has been universally accepted as the most secure form of welded mesh panel commercially available with significant inherent advantages over products such as chain link fencing or other forms of welded mesh fencing owing to its unique configuration.
358 mesh is a solution for preventing unauthorised access as the rectangular spacing of the horizontal and vertical wires make it unclimbable- yet they allow visibility.
Applications for the use of 358 mesh as high security fencing include airports, rail corridors, sub substations, power plants and commercial and industrial sites.
