Steel products manufacturer Andrew Mentis says that expanded metal is fast becoming a popular material to ensure the safety of people and warehoused items inside facilities.
The company says that, when compared with conventional fencing, expanded metal offers increased security coupled with unimpaired visibility, adding that it is particularly ideal for applications that include inventory-holding sections of manufacturing plants and warehouses.
Expanded metal is sheet metal that has been slit and expanded into a network of diamond shaped meshes. There are no welds or joints that can be unravelled or worked loose in the expanded metal sheets. Expanded metal sheets are also more impact resistant than other fencing materials. While providing an aesthetically pleasing security barrier, the expanded metal also allows unimpaired vision and free passage of air into enclosed areas.
Andrew Mentis marketing manager Elaine van Rooyen states that expanded metal offers numerous advantages over ordinary welded or diamond mesh, adding: “Unlike conventional materials, expanded metal is difficult, if not impossible, to cut. Numerous strands have to be separately cut before an opening can be made, which takes time and may alert residents of an intruder’s presence.
“The diamond mesh configuration does not offer hand or footholds, and the exposed edge on the top section makes it extremely difficult and dangerous for the intruder to scale.”
Expanded metal is normally supplied unpainted, but readily lends itself to any normal finishing processes, such as painting, stove enamelling, plating and galvanising. It can also be produced in 3CR12 and stainless steel should the application warrant this type of increased protection.
Van Rooyen concludes that expanded metal offers the same level of flexibility as conventional fencing materials and can be tailor-made for specific application requirements.
