The top of the fully enclosed noise barrier is designed with an arched shape, while the side panels are designed in a vertical style. This structural design primarily aims to balance factors such as the surrounding landscape, structural safety (wind load, snow load, etc.), and rainwater drainage. The side panels of the fully enclosed noise barrier are fixed to the main and auxiliary columns of the H-shaped steel with soundproofing PVC board material, using special self-tapping screws with rubber pads.

The sound barrier's top is also made of modified PVC panels, offering excellent lighting and harmonizing with the surrounding landscape. It boasts good corrosion and rain resistance, as well as easy installation and sealing.
