密度高、硬度高、压强高、重量轻、抗腐蚀、抗老化等优点。经权威部门检测，各项指标均超过国家标准，更是超过国内其它水泥预制件。 电脑控制水泥盖板配料比例，棱线平顺垂直、尺寸位置准确，支撑稳定、在浇注过程中不跑模、不变形。保证每一块水泥盖板结构相同。Light weight and high strength: the specific gravity is only 1 / 4 of steel, 2 / 3 of aluminum, and the strength is 10 times that of UPVC. The strength exceeds that of aluminum, reaching the level of ordinary steel.
