These items typically include bolts, nuts, washers, nord locks, joint materials such as EPDM strips used during installation. Their purpose is to ensure the correct assembly, alignment, and secure fixing of the precast acoustic panels and associated elements to the supporting structure. These consumables are essential to achieve the required structural stability, durability, and acoustic performance of the noise barrier system.
