在北京市施工城市建设中,施工工地星罗棋布,过去使用的红砖墙围挡,由于大量地挖掘耕地,破坏了生态环境,早已被市政府明令禁止。而其他砖墙也因为是用水泥砌垒起来的,拆除时,往往扬尘污染严重。为此,北京市建委规定,一律采用2米高、可以拆卸的复合材料板,淘汰砖墙,并于4月中旬开始实施。由于大部分建筑企业备有复合板,稍做加工,即可使用。一次性成本虽然增高,它能反复使用,拆装方便,企业易于接受,又给市容增姿添彩。另外,由于复合板易于着色,可以标上企业标志,或者涂上一幅画,使其成为树立企业形象的看板。 In Beijing’s construction of urban construction, construction sites spread over the past, the use of red brick walls, due to extensive mining of arable land, damaging the ecological environment, has long been the city hall banned. Other brick walls are also built with cement because they are heavily polluted by dust.

As most construction companies with composite board, a little processing, you can use. Although the one-time cost increase, it can be used repeatedly, disassembly convenient, easy to accept the business, but also to add appetite to the city appearance. In addition, as the composite board easy to color, you can mark the corporate logo, or painted a picture, making it a corporate image of the billboards.
