The panels with interlinked links assure excellent mechanical properties both in terms of endurance and actual expansion.  They are made up of links in spirally-wound galvanized steel individual wire to form a 9.0 or 12.0mm diameter strand, based on the individual wire diameter employed of 3.0 or 4.0 mm diameter. The diameter of the single link does not exceed 350 mm and the latter is interlinked to 4 or 6 other links and so on, to achieve a panel of the correct size.

Main features:

• Panel shape: square, rectangular etc.
• Panel size: with no limit
• Panel unit weight: no less than 6.0 kg/m2
  
• Single link size: 350mm max.
• Individual steel wire: 3.0 or 4.0 mm diameter
• Linkages: 4 or 6

The steel wire employed is standard-compliant with UNI-EN 10218, with a minimum resistance of 1570 N/mm2, protected against axidation by a galvanization coating according to UNI 7304/74 Class A amounting to no less than 340 g/m2.

The panels with interlinked links are used in rockfall barriers and are capable of absorbing considerable energy caused by falling boulders rolling off unstable slopes; the links are the elasto-plastic type and absorb considerable impact energy through deformation.  The forces, partially absorbed by the panel, are delivered to the supporting perimeter ropes and guylines, to the dampers and finally to the ground anchors.
