Industrial Steel Buildings Structural Design

Smartweigh Instrument Co.,Ltd | Updated: Nov 01, 2017

China is a steel power and manufacturing power, the 21st century steel production of about 7 billion tons, supporting the construction industry, industrial steel construction, shipbuilding, automobile and other related industries. At present, China has more than 3,000 steel construction enterprises, about 50 million employees, the output value of about 500 billion yuan. In 2014, steel production reached 42 million tons, more than Europe, the United States, Japan, Australia, the total output. However, the industrial plant construction in the "second Five Year Plan" period, China's steel and steel production accounted for only 5% to 6%, in a large area of residential construction and bridge structure, the proportion of steel structure is less than 1% In the developed countries, the average level of 20% to 30%. The main reason for this situation is that the support of China's steel structure development policy is not enough, the steel structure of the industrial chain configuration defects, industrial plant construction market operation mechanism is unreasonable, the lack of skilled steel structure design and other technical personnel, Lack of support for the product, the lack of steel production or market of large leading enterprises.

In order to solve the application of steel structure and the bottleneck of industrialization, the Chinese Academy of Engineering has set up a new structure and its urban and rural housing industry, such as "steel structure residential industry research" and "high performance structural engineering sustainable development strategy" project research project , Made a series of research results. At the same time, 25 Chinese Academy of Engineering industrial steel construction formed a "structural engineering, to promote the application of academician steel."

According to the National Assembly's steel structure civil construction industry technology innovation strategic alliance, China's steel industry has made some development, industrial plant construction last year's domestic steel production of more than 800 million tons, steel production capacity of about 50 million tons, higher than the steel production enterprises over 3000 scale, the construction of qualified enterprises over 10,000, a large number of successful construction of the world leading level of steel structure of the landmark project.

The steel industry has a typical "big industry, small company" features. China's steel industry is highly market-oriented, there are tens of thousands of iron and steel enterprises, highly competitive. According to the China Steel Association statistics, there are 375 units, qualified steel manufacturing enterprises, but most of them are less than 50 enterprises, the annual output of 10,000 tons or more. In 2014, industrial steel construction industrial steel construction, the country's largest five steel production accounts for about 7% of the national steel production. From the market point of view, in the field of light steel structure, due to the high degree of homogenization of the product, manufacturing difficult, the most intense competition; and high-grade heavy steel structure, large span space steel structure, bridge steel structure and equipment steel field, Due to the high degree of engineering technology, production and installation difficulties, high demand for funds, industrial plant construction product quality and accuracy requirements, relatively moderate competition, product gross margin higher.

Industry core competitiveness lies in capital, industrial steel construction technology, brand, experience, model and so on. As with other domestic projects, due to the factors of the settlement model, steel structures usually need to absorb more liquidity, the strong background of listed companies and corporate financing channels is rich, the advantage is more obvious. Technically, steel structure technical barriers are relatively high, light steel structure technical barriers are relatively low, but with the construction standards and requirements continue to improve, the need for continuous technological innovation. Brand as a comprehensive manifestation of quality, industrial steel construction technology and experience, is an important choice for the owners, taking into account the contractor, leading enterprises brand influence in the development of the market more favorable. In addition, industrial steel construction qualification, experience, model is also an important factor in competitiveness.
