S960 steel is lighter and stronger than commonly used S355 steel, making it an effective material for bridge construction. However, the welding process can reduce its mechanical properties, limiting its applications.

A research team from the Department of Civil and Environmental Engineering at The Hong Kong Polytechnic University (PolyU) has developed a welding technology for efficient applications of ultra-high strength S960 steel.

By precisely controlling the heat input during welding, the mechanical properties of the steel are maintained. This innovation has been adopted in recent footbridge construction in the Fanling North New Development Area, marking Hong Kong's first public works using S960 steel, and facilitating innovative application of high-strength steel in bridge construction.
