Side barrier
Vertical posts in “CORTEN®” S355J0WP or galvanized S355JR steel, “C” section 120x80x25 mm, 4 mm thick and 1450 mm long; driven into the ground to a depth of 775 mm and spaced 2000–4000–6000 mm apart. 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 solid-wood strips 60×50 mm and 1990 mm long partially covering the rail, suitably shaped and impregnated in line. The lower band is coated with a dedicated white reflective paint. 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. The strips are fixed to the rail with round-head bolts Cl. 4.8 M16x60; nuts and washers.
