1、制作成本低，原材料易采购。 2、制作方便，只需将配置好的钢纤维和混凝土装入塑模，振动成型即可，脱模周期短，投资小，劳动强度低。 3、抗压强度高，重型盖可通行挂车80吨，且结合部平实，车辆辗压无损伤、不打滑、不翻身、无噪音。 4、美观大方：采用注塑模具，砼制品座盖光滑、轻巧。

1, the production cost is low, the raw material is easy to purchase. 2, the manufacture is convenient, only need to configure the steel fiber and the concrete into the mold, forming vibration can release cycle is short, small investment, low labor intensity. 3, high compressive strength, heavy cover traffic Trailer 80 tons, and the combination of the vehicle rolling plain, no damage, no slipping, no noise, no turning. 4, beautiful and generous: with the injection mold, the concrete product seat cover is smooth and light.
