Although China made great achievements in iron structures in the early days, it stayed at the level of iron buildings for a long time. It was not until the end of the 19th century that my country began to adopt modern steel structures. After the founding of New China, the application of steel structures has been greatly developed, far exceeding the past in terms of quantity and quality. The floor of the light steel structure is composed of cold-formed thin-walled steel frame or composite beam, floor OSB structural plate, supports, connectors, etc. The materials used are oriented strand board, cement fiberboard, and plywood. These lightweight floors can withstand loads of 316 to 365 kilograms per square meter.

The number of steel structure buildings marks the economic strength and degree of economic development of a country or a region. After entering 2000, my country's national economy has grown significantly, its national strength has been significantly enhanced, and its steel production has become a world power. In the construction, it is proposed to "actively and reasonably use steel". Construction is gradually increasing in economically developed areas. Especially around 2008, under the impetus of the Olympic Games, there was a boom in steel structure buildings, and the strong market demand promoted the rapid development of steel structure buildings. A large number of steel structure venues, airports, stations and high-rise buildings were built. Among them, some Steel structure buildings are world-class in production and installation technology, such as Olympic stadiums and other buildings.

After the Olympic Games, steel structure buildings have been popularized and developed continuously. Steel structures are widely used in buildings, railways, bridges and houses. There are tens of thousands of steel structure enterprises of various sizes. The world's steel structure processing equipment is basically complete, such as multi-head multi-dimensional. Drilling machine, steel pipe multi-dimensional intersecting line cutting machine, corrugated plate automatic welding machine tool, etc. And now the processing and manufacturing level of hundreds of steel structure enterprises is at the world level, such as steel structure manufacturing and first-class enterprises. In recent years, the annual steel output has reached more than 600 million tons, and the steel varieties can fully meet the needs of construction. Steel structure design specifications, steel structure material standards, steel structure engineering construction quality acceptance specifications, as well as various specifications and enterprise construction methods are basically complete.
