(Summary description)
Although China had outstanding achievements in iron structures in the early days, due to the constraints of the feudal system for more than 2,000 years, science was not developed, so 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. Each square meter of these lightweight floors can bear a load of 316 to 365 kilograms. The number of steel structure buildings indicates the economic strength and economic development of a country or a region. After entering 2000, my country's national economy has grown significantly, its national strength has increased significantly, and its steel production has become a world power. 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 have a world-class level in production and installation technology, such as the Olympic National Stadium 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, and the world's advanced steel structure processing equipment is basically complete, such as Multi-head multi-dimensional drilling machine, steel pipe multi-dimensional intersecting wire cutting machine, corrugated plate automatic welding machine tool, etc. And now the processing and production level of hundreds of steel structure enterprises has reached the world's advanced level, such as steel structure manufacturing super 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 professional specifications and enterprise construction methods are basically complete. The downstream industry of steel structure has a greater traction and driving effect on the development of the steel structure industry, and their demand changes directly determine the future development of the industry. 1. The upstream industry of steel structure is the raw material supply industry such as steel The steel industry is the material basis for the development of the steel structure industry, and the technological progress of the steel industry has created favorable conditions for the application of steel structures. Some large enterprises in the domestic steel industry have started the research and development of steel varieties and technologies for building structures, and have successively developed high-strength steel and steel for fire resistance, weather resistance, seawater resistance, laminar tear resistance, and low temperature resistance, as well as H-beam, high Performance color-coated steel plates, cold-formed steels, etc., have laid a good application foundation for the development of the steel structure industry. 2. The impact of upstream and downstream on the industry The upstream of the steel structure is mainly the steel industry, and the price fluctuation of steel products directly affects the procurement cost of the industry. On the whole, the upstream industry is basically a competitive industry, producing various types of steel plates, steel pipes, section steels and other steel materials for steel structures. Among them, H-beams and medium and heavy plates are the most commonly used products in steel structure buildings. Industry Insights Research Data In 2011, the crude steel output reached 696 million tons, and the output was relatively saturated. The raw materials required for the production of steel structures could obtain a stable supply. The downstream industries have a greater traction and driving effect on the development of the steel structure industry, and their demand changes directly determine the future development of the industry.

In addition, once the residential steel structure market makes a breakthrough and gradually replaces the traditional building form into the field of residential construction, the steel structure industry will lead to explosive growth.
