How about the bridge bearing of Zhongjiao Luda?

Sichuan CCCC Luda Transportation Technology Co., Ltd. not only has its own scientific research team, but also has established long-term strategic cooperative relations with provincial and ministerial scientific research institutions such as CCCC Gong Yi Institute, Southwest Jiaotong University and Yunnan Transportation Planning and Design Institute, and independently researched and developed new materials and new processes, and obtained many national patents and product certification certificates. For example, the plate rubber bearings produced by CCCC Luda are divided into ordinary plate rubber bearings and tetrafluoroethylene sliding rubber bearings, which have the advantages of simple structure, convenient processing, less steel consumption, low cost, convenient installation and reliable working performance. Moreover, the plate rubber bearings produced by CCCC Luda hardly need regular maintenance, and have excellent bearing capacity, ultra-high corrosion resistance and ultra-high durability, which can even improve the overall seismic performance of bridges, not only reducing many bridges, but also asking me if you don't understand.
