Pretkāpšanas metināto sietu sistēma (Pazīstams arī kā cietuma acs vai 358 acs) To galvenokārt izmanto žogu sistēmās, kas paredzētas, lai nodrošinātu maksimālu perimetra aizsardzību vietā, netraucējot redzamību (kas ir svarīgi cilvēku patrulēšanai vai videonovērošanai). 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.
