Product Description
Rockfall Netting or drapery systems, made from double-twisted "DT" steel wire mesh, are designed to control rockfall movement by guiding falling debris to a collection point at the toe of the slope to protect structures from damage. Commonly used as 'drapery', DT mesh provides a protective curtain on the slope; any rocks and debris detaching from the slope are contained behind the mesh. The open wire mesh structure also allows the slope to return back to its natural state after repair by promoting the regeneration of vegetation.

Steel wire used for double twist hexagonal mesh
-Tensile strength: The wire used for the manufacture of mesh shall have a tensile strength between 380-550N/mm2 (EN 10223-3). Wire tolerances are in accordance with EN 10218 (Class T1).
-Elongation: Elongation shall be not lower than 9%, (EN 10223-3).
-Coating: Minimum quantities of Zn-5%Al meet the requirements of EN 10244-2 (Class A).
-Adhesion of Zn-5%Al: The adhesion of the Zn-5%Al coating to the wire shall be in accordance with EN 10244-2.
-Outwearing accelerated aging test: In a general condensation of moisture containing sulfur dioxide test (28 cycles) according to EN ISO 6988 (without showing signs of red rust).
