S960 Ultra-High-Strength Steel Pedestrian Bridge Project Successfully Assembled and Lifted
The bridge project marks the first global application of S960 high-strength steel in civil bridge construction, serving as a benchmark for future bridge-building initiatives in the construction industry.
Using S960 high-strength steel significantly reduces the bridge's weight and the number of foundation piles, saving land space while lowering carbon emissions and enhancing project sustainability.1 Additionally, S960 components can be prefabricated in factories, drastically reducing on-site procedures. Compared to traditional methods, on-site assembly cuts carbon emissions by 35% and shortens the construction period by 40%, accelerating progress, improving quality, enhancing efficiency, and increasing output.
This high-stakes, technically demanding project received robust support from government, industry, and academia throughout implementation.1 Execution ensured not only high-quality material delivery but also precision services in cutting, forming, welding, and surface treatment. Critical technical challenges-such as deformation control of high-strength steel and stringent welding procedures-were resolved, guaranteeing project timeline and quality adherence.
What is S960 steel structural Sections?
S960 steel is a structural steel grade that belongs to the S series of high-strength steels. It is specifically designed to provide exceptional strength, durability, and performance in demanding structural applications. GNEE Steel Group launches S960QL structural steel profiles for the market, (H-shaped steel, I-beam, channel steel, round tube, square tube, flat tube…) ultra-high strength steel structural profiles
