The panels are manufactured on frames of varying size in order to achieve, based on requirement, varying shapes and dimensions by a process where a single galvanized 8.00mm diameter steel rope is first woven diagonally and is crisscrossed alternatively above and below.  The overlap nodes are blocked by two rim-pressed steel shells to form a boss and the panel meshes are connected, through suitably pressed aluminium sleeves, to a galvanized 14.00 or 16.00mm diameter steel rope.

Main features:

• Panel shape: triangular, square, rectangular.
• Panel size: 3.0x5.0 m, 4.0x6.0 m, etc.
• Mesh size: 150x150 mm, 200x200 mm, 250x250 mm, etc.

Based on the use, the rope panels with knots covered by boss are divided as follows:

• Panels with knots covered by light-duty boss for rock face active defence measures;
  
• Panels with knots covered by heavy-duty boss for rockfall barrier panels.

The types of ropes employed are in galvanized steel and standard-compliant with UNI UNI 7292-74 with individual wire class of 180 N/mm2 e 200 N/mm2.

To blend into their enviroment, steel ropes can be painted in various shades of green.
