Although China had outstanding achievements in iron structures in the early stages, due to the constraints of over 2000 years of feudal system and underdeveloped science, it remained at the level of iron buildings for a long time. It was not until the late 19th century that China began to adopt modern steel structures. After the establishment of the People's Republic of China, the application of steel structures has made great progress, far surpassing the past in terms of quantity and quality. We have achieved a high level of technical proficiency in design, manufacturing, and installation, and have mastered the design and construction techniques of various complex buildings. We have built many large-scale and complex steel structure factories, large-span steel structure civil buildings, and railway bridges across the country, including the steel roof truss of the Great Hall of the People in China, and the steel grid truss of sports stadiums in Beijing and Shanghai, The three hinge steel arch of the Shaanxi Qin Shi Huang Military and Horse Servant Exhibition Hall and the Bird's Nest in Beijing.

The floor of light steel structure consists of cold-formed thin-walled steel frames or composite beams, floor OSB structural plates, supports, connectors, etc. The materials used are oriented particle board, cement fiber board, and plywood. These lightweight floors can withstand a load of 316-365 kilograms per square meter. The floor structure system component of the light steel structure residential building of Maite Building is only one-fourth to one-sixth of the traditional concrete floor system in China, but its floor structure height will be 100-120 millimeters higher than the general concrete slab.

The number of steel structure buildings indicates the economic strength and level of economic development of a country or region. Since the year 2000, China's national economy has significantly increased, its national strength has significantly strengthened, and its steel production has become an international power. It has proposed to "actively and reasonably use steel" in construction, freeing up the constraints of "restricting the use of steel" and gradually increasing the number of steel structure buildings in economically developed regions. Especially around 2008, with the promotion of the Olympic Games, there was a wave of steel structure construction, strong market demand, and the rapid development of steel structure construction. A large number of steel structure venues, airports, stations, and high-rise buildings were built, among which some steel structure buildings have world-class manufacturing and installation technology, such as the Olympic National Stadium and other buildings.

After the Olympics, steel structure buildings were popularized and continuously developed, and steel structures were widely used in buildings, railways, bridges, and residential areas. There were tens of thousands of steel structure enterprises of various scales, and internationally advanced steel structure processing equipment was basically complete, such as multi head multi-dimensional drilling machines, steel pipe multi-dimensional intersecting line cutting machines, corrugated plate automatic welding machines, etc. We also have self-developed bending and torsion component processing equipment and methods, and the processing and manufacturing level of hundreds of steel structure enterprises has reached international advanced levels, such as special and first-class steel structure manufacturing enterprises. In recent years, the annual production of steel has reached over 600 million tons, and the variety of steel can fully meet the needs of construction. The steel structure design specifications, steel structure data standards, steel structure engineering construction quality acceptance specifications, as well as various professional specifications and enterprise construction methods are basically complete.
