The exterior structure of the "Bird's Nest" is mainly composed of portal steel frames with a total of 24 truss columns. The whole building has abandoned the traditional support columns, and a large number of box-shaped components welded by steel plates are used. The 24 truss columns support the world's largest Its roof structure can be regarded as a masterpiece in the history of world architecture.
To achieve such a feat, if there is no large-thickness Q460 steel that undertakes the main load-bearing task, everything can only remain on imagination and drawings. Q460 is a low-alloy high-strength steel containing niobium. It can only undergo plastic deformation when the stress strength reaches 460 MPa. Only with this performance index can it become the backbone of the special structure of the National Stadium.
Strong infrastructure growth in China is also based on the use of niobium micro-alloyed steels. Niobium is an important element in addressing project needs when materials with higher strength, toughness, and weldability are required. Niobium micro-alloyed steel means higher strength and higher toughness, providing designers with the possibility to use more streamlined designs for multiple structures, helping China to build architectural masterpieces that amaze the world one after another.
