Expanded mesh is an effective security tool in many applications.

Expanded mesh and security: A guide

Security is a foundational concern for each and every construction project and for the building or structure that exists upon successful completion. Limiting access is important in applications from office buildings to malls and mixed-use facilities.

Certain types of buildings and properties, like farms and prisons, have heightened and unique security needs, whether to keep detainees inside or prevent wild animals from accessing crops and livestock. And even car parks and similar structures must keep people inside from falling from a dangerous height.

"Expanded mesh is a versatile solution for many needs related to security."

Expanded mesh is a versatile solution for many needs related to security, offering a powerful combination of cost-effectiveness, durability and overall success in its intended uses. Let's take a closer look at what expanded mesh is, and how it can be a powerful and reliable addition to a variety of projects where security is a priority.

How is expanded mesh made?

Expanded mesh starts with a piece of base material, such as steel or aluminium. The manufacturing process cuts and stretches the single sheet  until the cuts open up to form a shape similar to a diamond or lattice pattern. However, each sheet of expanded metal remains connected,  a crucial difference from woven wire and similar products.

The structure of expanded metal mesh makes it stronger, lighter and more rigid than it was as an unprocessed sheet of base material, offering significant advantages in construction, security and many other applications. And, because it maintains its integrity as a single piece of metal, it maintains its strength as well.

Foundational qualities of expanded metal mesh

Expanded metal mesh can be fabricated to meet a variety of needs. While security is a common application, many others exist. Super-rib mesh, for example, is used to strengthen construction materials, supporting safe and sturdy buildings.

The singular nature of each expanded metal mesh panel is worth noting in this context as well. We have already discussed the strength and durability advantages of this product, and there's another one to keep in mind: There's no risk of the mesh fraying or unravelling. Because each panel is made from a single sheet of base material, it eliminates the possibility of becoming unwoven or easily accessible due to fraying.

Selecting a specific type of metal with desirable qualities to use as expanded mesh, such as the corrosion resistance offered by aluminium, adds even more benefits.

Expanded mesh as an effective security barrier

Durability and strength are key qualities for security applications in general. When it comes to physical barriers to prevent entry or egress, expanded metal mesh can easily fit the bill. There are man different applications, including:

Prison and corrections security

Keeping convicted offenders within the limits of a prison or correctional facility is a paramount need, and the basic function the building is designed to fulfil. While many different measures must be carefully coordinated to achieve a high level of security, expanded mesh can play a key role in defining the perimeter of a facility. Its resiliency makes it an effective deterrent both to those attempting to enter the facility without authorisation and inmates attempting to leave before their sentences end.

Locker has developed an expanded mesh product in conjunction with the New South Wales Department of Corrective Services for this specific purpose. It is now used across Australia, New Zealand and Papua New Guinea.

Car park enclosures

Car parks must be enclosed to align with relevant building and safety regulations, and to keep people accessing and using them safe. Expanded mesh is exceptionally reliable in this context. As each panel is a single sheet of metal, concerns related to this protective element unravelling or becoming frayed and therefore creating a source of danger are effectively mitigated. While careful installation is still required, this strategy for protecting people inside of car parks is a useful one. And expanded mesh is similarly effective at preventing access to the facility outside of designated areas, offering additional benefits.

Windows and doors: Security mesh

Correctional institutions, car parks and other large structures require large-scale security solutions. When it comes to individual doors and windows, the size of the security measure decreases, but it is no less important. Locker has developed a range of metal mesh that capably addresses these needs, with products including:

  • DVA: This traditional style of metal mesh offers two key benefits: Preventing insects from accessing the interior of a building and providing one-way vision, where those inside can see out, but anyone outside of the home can't see in.
  • Super RV: Part of the DVA range, this expanded mesh offers the same advantages as DVA while also meeting regulatory requirements to be classified as security mesh. Because it meets Australian standards for knife sheer and impact, it can be effectively and compliantly used in open-frame security doors.
  • SMAB: A perforated security mesh, SMAB prevents the entry of small embers into a building. Its small perforations allow for a high degree of visibility while indoors, and align with bushfire codes.
