Welded mesh Zenith

Sensitive and reliable

Perimeter protection is paramount for utility companies, nuclear power stations, airports, military sites, and oil and gas terminals. The higher the safety risk to people, premises and assets, the more important it is to ensure that robust and effective security systems are in place. Heras’ Zenith high security mesh fencing systems are the answer; they’re LPCB certified, extremely safe and secure, easy to install and designed to last.

The Zenith range includes Zenith SR1, Zenith SR2 and Zenith SR3. Zenith system offers a high level of protection against vandalism, intrusion and terrorist activity thanks to the combination of its anti-climbing 358 mesh system, secure foundations and security toppings, such as barbed wire. Each Zenith system has been designed to meet a range of security needs and has been rigorously tested by the Building Research Establishment to gain the necessary security ratings (SR) to meet industry standards.

  • Zenith SR1 represents a lower level security to prevent against opportunistic attacks by bodily force using minimal tools e.g. knife.
  • Zenith SR2 offers protection against a more determined opportunist attack with tools of a higher mechanical advantage e.g. bolt cutters.
  • Zenith SR3 offers a more comprehensive solution where organisations want to protect their most critical assets from deliberate forced entry of protected premises using bodily force and a selection of attack options for example, crowbar

The Zenith range also includes XS ‘Sensor fence’, which is listed on the CPNI Catalogue of Security Equipment.


Zenith SR1 Single skin

Zenith SR1 is made up of a single panel of welded steel mesh skin. It is suitable for protecting large areas and premises as businesses, schools, hospitals and manufacturing sites against opportunistic attacks. It could, for example, provide necessary level of security at a school, while keeping children’s fingers out.

Zenith SR2 Double skin

Zenith SR2 is made up of two layers of steel mesh panels welded 90 degrees to each other to provide an extra safeguard against intrusion and a more determined attack.

It requires that the fence is clamped or buried into the ground, and this special foundation provides extra protection in the ground against unwanted visitors. The Zenith SR2 offers comprehensive protection for utility companies, airports, ports and railways, and data centres.


Zenith SR3 Triple skin

Zenith SR3 is combination of Zenith SR1 and Zenith SR2, where a single skin fence is located just in front of a double skin fence creating a gap to resist and significantly delay a sustained attack.

The Zenith SR3 must be clamped or buried into the ground and is used to protect the most critical assets such as high security areas within power stations, research centres, oil and gas terminals, military and utility sites. It may be used as additional protection for critical assets in a protected site that already have SR1 or SR2 perimeter protection.

Experts in perimeter protection

Physical perimeter protection is best explained as systems and technologies designed to protect people and assets within a defined area by preventing unauthorised physical intrusions.

The primary defense is the perimeter boundary for which we designed the Heras Security Model. This model serves 5 goals: to demarcate the boundary of the premises, to deter, delay and detect unwanted intrusion and to deny access for unauthorised parties.

Heras has successfully met and exceeded customer safety and security needs across Europe for almost 70 years. It is this track record, combined with the ever-developing skill set of our personnel that enables us to say that we are the Experts in perimeter protection.
