The system (1) has cross-sectional profiles with spacers (5, 6) provided between a post (2) and a protective plank (4) that is designed as two-wavy profile. One of the spacers with a profile projecting from flanges with an upper plank leg is firmly connected with the other spacer with another profile projecting from the flange with a lower plank leg of the protective plank. Thrust center points of the profiles are horizontally offset from each other. A carrying profile (7) and the post are parallel to mounting brackets. |
