桥梁、隧道由于其功能特性，经常在穿越群山、横跨江海、贯通天堑、潜接两岸等建筑工程中发光发热，该环境对紧固件高强度、耐腐蚀等要求特别高。高耐蚀性材质紧固件产品，从材料本质出发，适用于各种高碱性、高酸性地下和海洋环境。
Because of their functional characteristics, bridges and tunnels often play a role in construction projects such as crossing mountains, crossing rivers and seas and penetrating natural cutting. High strength and corrosion resistance of fasteners are required in such occasions. The fastener products with high corrosion resistance materials are applicable to various underground and marine environments with high alkalinity and high acidity.
