| Use advice for data set | PoliMac STEELGRID and MACARMOUR are engineered to fit the use as: • drapery system controlling and preventing rock fall and loose debris flow; • soil nailing system; • erosion control system, along relevant structures as roads, highways and railways, where higher level of tensile strength and punching resistance at low-strain, compared with standard double twist steel wire mesh, are requested. PoliMac STEELGRID and MACARMOUR are CE marked in compliance with Regulation (EU) 305/2011, according to EAD 230008-00-0106. |

| General comment on data set | The EPD is based on the composition of PoliMac STEELGRID HR30 8127. The LCA results can also be scaled to other STEELGRID and MACARMOUR products by using weight for different rope spacing and applying the scaling function reported in section 7. The EPD type is Cradle to gate with options, modules C1-C4, and module D. Kiwa-Ecobility Experts assumes no liability for manufacturer's information, LCA data and evidence. |

| Technology description including background system | PoliMac STEELGRID and MACARMOUR are composites of double twisted steel wire hexagonal mesh with high tensile strength steel cables, woven into the mesh in longitudinal direction (STEELGRID) or both in longitudinal and transversal direction (MACARMOUR), during the manufacturing process. PoliMac STEELGRID and MACARMOUR are made from high quality steel wire and ropes, which are heavily galvanised (Zinc-Aluminum alloy in accordance with EN 10244-2 and ISO 7989-2 - Class A). The additional protective polymeric (PoliMac) coating is applied for use in aggressive environments and where a longer design life is required. The manufacturing is carried out in Laguna plant (Philippines) by Maccaferri Philippines Manufacturing, Inc. The production process includes the weaving of the double twist wire mesh, starting from steel wire, onto which the PoliMac coating can be applied at the plant through an extrusion process of the polymer, and PoliMac wire rope, that can be inserted in longitudinal and transversal direction. |
