This product is designed to different structure composite product which according to the requirements of the bridges and protection of the product size,traffic characteristics. Inside will be put energy dissipation structure materials, filled with high-performance obturator energy absorption materials, mainly in order to absorb the impact force of ship( car) hit consumption, and to change the ship (car) driving direction in order to protect bridge or ship body structure ( car) from damage. Making full use of the composite material's features such as corrosion resistance, long life application and good structural performance, so that this facilities can be used at precipitation,water, river or sea impact sediment etc all kinds of bad environment. This product give full play of the high toughness of the material, and the features of ageing resistance, using composite material crushing, pressing, friction gradually absorb the impact energy moments of impact, which can have the effect of safety protection.
