Polymer resin concrete cover,in full accordance with the request of the customers, is prefabricated in workshops, which ensures the quality of products. By comparison with traditional cement concrete channel, it is made out of polymer resin concrete. Its chief raw materials are small stones and sands ,and auxiliary raw materials are unsaturated resin and solidifing materials. The polymer resin concrete cover has four characteristics. First, the producing method effectivly helps to reduce the cost. Second, it can’t be recycled, in other words, it won’t be stolen. Third, it is hard and durable, reducing the cost of replacing and maintaining. Fourth, polymer resin is harmless to human society and natural environment,so the cover is green product.
