The Beijing National Stadium, commonly known as the Bird's Nest, was primarily constructed using steel and concrete. Its iconic structure features a distinctive lattice of steel beams that create a nest-like appearance, with around 42,000 tons of steel used in its design. The stadium also incorporates a Teflon-coated fiberglass roof, providing protection while allowing natural light to filter through. This innovative combination of materials contributes to both the aesthetic and functional qualities of the venue.
