镀锌板声屏障：
Galvanized sheet noise barrier:
这种声屏障是目前应用最为广泛的一种金属声屏障，它造价低、造型美观、便于运输。同时它吸声效果好，性价比高，耐腐蚀性也好，拆卸式安装，后期维护方便。是隔音降噪的佳品。
This kind of noise barrier is the most widely used metal noise barrier at present. It has low cost, beautiful appearance and is easy to transport. At the same time, it has good sound absorption effect, high cost performance, good corrosion resistance, disassembly installation, convenient maintenance in the later period. It is a good product of sound insulation and noise reduction.
镀锌板声屏障的缺点就是耐腐蚀年限比不上铝板声屏障，美观性没有透明声屏障好，这也是金属声屏障的共同点。
The disadvantage of galvanized sheet noise barrier is that its corrosion resistance is not as good as that of aluminium sheet noise barrier, and its aesthetics is not as good as that of transparent noise barrier, which is also the common feature of metal noise barrier.
