挡风墙是由挡风板、钢结构支撑和混凝土基础组成，同事可附加1~2米的挡料挡墙和钢架上的照明灯具。
The retaining wall is composed of wind shield, steel structure support and concrete foundation. Colleagues can add 1-2 meters of retaining wall and lighting fixtures on the steel frame.
挡风板上有一定数量的开孔，挡风板的材质可分为金属和非金属。在金属挡风板中，又由于基材的不同可以分为碳钢板、镀锌板、镀铝锌板、不锈钢板、铝镁合金板等等；非金属的有手工玻璃钢、机械加工玻璃钢、高分子复合材料等等。高分子主要就是化学原料加工的，品种众多，当然质量也是千差万别。
There are a certain number of openings on the wind shield, and the material of the wind shield can be divided into metal and non-metal. In the metal wind shield, it can be divided into carbon steel plate, galvanized plate, aluminum zinc plate, stainless steel plate, aluminum magnesium alloy plate, etc. due to the different base materials; the non-metallic ones include manual glass fiber reinforced plastics, mechanical processing glass fiber reinforced plastics, polymer composite materials, etc. Polymers are mainly processed from chemical raw materials. There are many varieties, and of course, their quality varies greatly.
