Recently, Gao Wensheng, Director of the Institute of Foundation Engineering of the China Academy of Building Research Co., Ltd., visited Beijing Wulongxing Technology Development Co., Ltd. for inspection and exchange, accompanied by General Manager Wang Kaiyu and Deputy General Manager Wang Jianyu. The main purpose was to discuss the use of double threaded sleeves and the connection of prefabricated construction steel bars, further deepening strategic cooperation and jointly accelerating the high-quality development of the foundation engineering market.

Wang Jianyu, Deputy General Manager of Beijing Wulongxing, explains the horizontal and vertical integral connection technology of steel mesh.

General Manager Wang Kaiyu extended a warm welcome to Director Gao and his delegation, and accompanied them on a tour of the production and manufacturing workshop and the intelligent automatic production line for straight thread rolling of steel bars. He introduced the current reform and development, business operations, future strategic goals, and research on major special projects. Through the introduction, it can be understood that the WL double threaded sleeve steel bar connection technology is a product that conforms to the development of the times. At a time when the country is promoting new-type building industrialization, it can achieve prefabricated connection of steel bars and modular construction, featuring green environmental protection, energy conservation and emission reduction, standardization, and mass production, actively responding to the country's requirements for sustainable development strategies in the construction industry.

Director Gao expressed appreciation for Beijing Wulongxing's corporate mission of solidly researching scientific topics and specializing in utility model technologies, and thanked Beijing Wulongxing for its care and support for the development of the Institute of Foundation Engineering. He hoped that both sides would actively leverage their respective advantages, comprehensively strengthen alignment and cooperation, and achieve mutual benefit and win-win results.

Wang Jianyu, Deputy General Manager of Beijing Wulongxing, explains the integral connection technology of PC components.

This inspection and research activity not only deepened the friendly cooperative relationship between the Institute of Foundation Engineering and Beijing Wulongxing, but also further demonstrated the outstanding strength of both sides in the field of foundation engineering. Both sides will continue to be committed to providing high-quality products and efficient services, creating greater value for customers and jointly creating a better future.
