A horizontal double-wave rail in “CORTEN®” S355J0WP or galvanized S355JR steel, 4318×310 mm, 2.5 mm thick, is fixed to the posts. The horizontal band is completed with wood cladding of the rail, made of half-poles Ø160 mm and 1990 mm long, suitably shaped and autoclave-treated. The barrier can be upgraded by removing the wood cladding “kit”, redefining the device into a barrier of the same certified class. The steel components are joined by high-strength round-head bolts Cl. 8.8 M16x40 (Rail–Post, with an added slot-cover plate), and M16x30 (Rail–Rail); nuts and washers.
