The perfect example of a true multi-use fencing system, the ArmaMeshTWIN double wire panel system is suitable anywhere you need anti-cut-through protection. Designed for Commercial Fencing projects it is also suitable for school playgrounds, retail premises, business parks, public buildings and secure car parks.


ArmaMeshTWIN is manufactured from twin 6mm diameter horizontal wires either side of 5mm diameter vertical wires, providing an excellent defence against vandals and intruders.

Panels are fixed to steel posts using metal clips with tamper-proof angled returns, which are secured in place with pin hex screws for added security. And if you need even more protection, ArmaMeshTWIN is available in a Secured by Design option – ArmaMeshTWIN SR1.

For quality assurance and added peace of mind, the system also conforms to BS 1722-14 for open mesh steel panel fences.
