High-rise Buildings: Shanghai Tower (632 meters total height), adopts a "giant frame - core tube - cantilever truss" structural system, with a steel structure usage of 550,000 tons.
Large-span Buildings: National Stadium (Bird's Nest), steel structure woven "bird's nest" shape, with a steel usage of about 42,000 tons, reflecting the application of steel structures in complex shapes.
Industrial Buildings: Baosteel large factory buildings, utilizing the large-span characteristics of steel structures to meet the installation and production needs of heavy equipment.

Performance Advantages
High Strength, Light Weight: The strength of steel is about 10 times that of concrete. Under the same load, steel structure components have smaller sections and lighter weight, which can reduce the cost of the foundation.
Good Seismic Performance: Steel has good ductility and can absorb seismic energy, making the structure less prone to collapse during earthquakes.
Short Construction Cycle: Components can be prefabricated in the factory and assembled on-site, reducing wet work and accelerating project progress.
High Space Utilization Rate: Small component sections can increase the building's usable area and facilitate flexible space arrangement.
Green and Environmentally Friendly: Steel can be 100% recycled, with minimal pollution during construction, in line with the concept of sustainable development.

Broad Prospects. Currently, the goals of China's construction industry development are: to improve the overall quality of the construction industry, the level of industrial production and technological equipment, to achieve strong competitiveness in the international construction market, and to fully utilize the leading role of the construction industry in driving national economic growth and structural adjustment. By 2010, the construction industry will become a truly pillar industry of the national economy. The construction industry needs to drive the development of related industries, and accelerating the development of steel structure engineering is a very important aspect. Steel structure systems have comprehensive advantages such as light weight, easy installation, short construction cycle, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, they have unique advantages in the development of "high, large, and light" aspects.
