China Steel Industry Situation Analysis and Prospects

Steel Product Introduction
Steel is a steel-based construction structure, it is one of the main structural types of engineering construction, steel is one of Hainan modern construction engineering structure more common way.
The basic characteristics of the steel is a high strength, light weight, good rigidity, strong deformation, and therefore particularly suitable for creating large span and high, super-heavy construction material. In addition, homogeneous and isotropic steel is good, is the ideal elastomer, best meet the basic assumptions of general engineering mechanics; information plasticity, toughness, may have large deformation, can well withstand dynamic loads; the construction of short duration; its high degree of industrialization, can be a high degree of mechanization of specialized production.
Currently, the main industrial use Chinese steel comprises: architecture (the main structure housing construction, locomotives, ships), structures (tower mast, oil platforms, gates, brackets, etc.) and machinery and equipment (construction machinery, cranes, containers, blast furnace , boilers, transmission equipment, etc.). Throughout the downstream steel industry, housing construction accounted for more than half the amount of steel; various non-standard steel structures and mechanical equipment used together accounted for almost half. According Steel Association in 2009 to focus the company's steel survey: construction structures (factories, more high-level, public construction) to 5.815 million tons, accounting for 54% of the proportion of applications. The following non-standard steel 2,468,000 tons in turn, bridges 957,000 tons, the other 800,000 tons, 721,000 tons tower mast. Among them, the construction of steel structure topped plant utilization amount of 2.902 million tons, accounting for 49 percent, followed by the application of public construction, high-rise steel structure, multi-steel structure, the proportion respectively: 21%, 17%, 13% .

Steel Product Features
Seismic Wind: good ductility of steel, plastic deformation ability, excellent seismic performance wind, for the construction can take advantage of this feature, greatly improve the stability of construction. Especially in the case of an earthquake, hurricane and other disaster, the steel can be useful to avoid the collapse of the construction material destruction.
Durable: Steel itself after processing and surface treatment, corrosion resistance and durability. This makes steel structures in service compared to other wood structure longer.
Means convenience: basic steel components factory production, the scene usually only be means of fasteners and bolts, construction period is shorter. This facilitates the return of investors' capital, but also saves labor costs.
Energy Saving: Compared concrete construction, no sand, stone, cement and other construction when steel, greatly reducing the amount of construction materials, the main data used is steel. Further, in the construction was removed, most of the information can be reused or degradation, reducing pollution. Hainan Steel

Status Quo domestic steel occupations
In recent years, significant strengths of steel brought a boom to build the country's steel industry, research, design, production, and other fields supporting steel structures have been carried out rapidly. October 2007, the Ministry approved the establishment of the "National Steel Engineering Technology Research Center" in the construction of China Metallurgical Group Research Institute was established. In June 2008, the construction of steel structures Engineering Research Center was established in Shanghai Tongji University. At the same time, emerging career within the steel structure outstanding design, design software and scientific research, they increase the steel structure design, construction quality; enhance professional standards and procedures. From the steel company's growth rate and create a level, a large number of the strength of the steel company undertook the production and the domestic focus of large-scale steel works equipment, new technologies, new construction methods, new equipment after another, also reached the level of construction equipment the international advanced level; steel structure supporting products complete processing equipment manufacturer for rapid and better meet the needs of steel professional conduct. At present, China's output of steel structures, industrial scale shopping malls are among the first in the world to develop applications, equipment manufacturing and equipment technology has reached world advanced level.
Since vocational and technical demanding, less access conditions, uneven texture steel company, occupational fierce competition. Currently, the number of the country's steel company over a million, but with a certain scale, the company has fixed production sites in 5000 or so, the company has a level of more than 400 steel professional qualifications, the processing capacity of 5 million tons of large-scale Steel company has nearly 50. The leading steel company excellent product quality, leading the profession to carry out the direction, good at absorbing and digesting the current international advanced technological achievements, in some technical areas have reached or exceeded the international advanced level.
In the geographical distribution, China's steel industry showed uneven distribution, the irrational status quo, steel companies are mainly concentrated in the Yangtze River Delta, Beijing and Tianjin and the Pearl River Delta and other coastal areas, less industrial Midwest distribution, industrial level is not high. Looking at the country, the number of companies in the lot, but on the scale, influential, strong brand company much. Although China is a big country of steel, but not the steel powerhouse, with iron and steel occupation exists excess capacity, internal contradictions mall severe oversupply, steel occupations require merit future conduct.

The current industrial policy support
China 30 years of reform and opening up and economic development, has created a very favorable environment for the application to carry out steel system. "2010-2015 Steel" Twelfth Five Year Plan "policy advocated (draft)," he pointed out:
1, strive to be included in the national steel industry "second five" strategic planning of new industries, so as to obtain support of national ministries and relevant guidelines. Focused towers, construction industry in the national economy growth, output, output value proportion prominence in professions steel housing, steel bridges and non-standard, potentially mall outfit manufacturing and innovative technologies to carry out, so Chinese steel industry occupies an important position at home and abroad, to truly become strategic emerging industries.
2, increase investment in steel design specification relating to the revision of norms, improve China's housing construction, bridge, tower mast, containers and other steel norms, improve the design life and meet environmental green, low-carbon and circular economy, promote autonomy innovation and modernization construction of China's more scientific, civilized.
3, to promote the development and application of high-performance steels, in the "five" period argue that the development of 60kg high-strength, high toughness and good weldability of steel plate and profiles, comprises a refractory weathering resistance, low temperature, resistance to seawater corrosion resistance, chemical medium corrosion functional steel for the construction of bridges, tower mast, container, marine equipment manufacturing upgrading and updating of information provided. Very Good, fuller play to the rational use of resources, a common recommendation steel occupation innovation, creativity and scientific and technological progress.
4, continued to build the steel manufacturing industry in depth, so that steel production 25 million tons in 2010, based on more than double by 2015 to reach 5000-6500 tons. Strive steel production reached 10% of the country's crude steel output policy. Steel manufacturing company integrated technology reached the international advanced level.

Looking steel occupations
1, the energy will further accelerate the construction of the main plant and boiler steel steel plant will add the amount of firepower (including nuclear power plants steel plants, wind power steel, etc.).
2, traffic engineering will be added in the bridge, railway bridges are made of steel, the choice of steel highway bridges in recent years has become a trend to carry out, the Beijing-Shanghai high-speed, cross-sea, the choice of steel bridge across the river bridge, Highway Guardrail, toll stations, the amount of steel is also a lot of traffic signs, the new airport terminal building and expansion projects, the platform of the train station waiting hall and keep adding.
3, choose the amount of municipal construction steel structures will be added, subway and light rail projects, urban overpass, viaduct, environmental engineering, urban public facilities and temporary housing etc. increasing to choose steel.
4, will add steel housing. The state promotes land-efficient housing construction, design specifications related to steel housing and supporting technology, basic materials have. At present, China only a few million square meters of residential steel developed countries has reached 40 to 50 percent. If China each year completed the construction of 600 million square meters of residential townships have chosen 5% steel, the multilayer, high-rise construction of an average of 50 kg / m steel design, steel consumption will reach 1.5 million tons per year. This is not yet included in the statistics of rural construction with steel.
"Thirteen Five" period, adjusted according to the national industrial policy, focusing on supporting a number of low energy, management of large-scale steel company, to enhance the entire professional conduct quality, to adapt to the needs of the mall, the phasing out of part of the informal, shoddy, low efficiency The high-energy company, to further standardize the order of Chinese steel mall career. To carry out scientific research and technological innovation activities in steel occupations, the relevant state departments should support the introduction of appropriate industrial policy, to invest the necessary funds to support the development and application of steel, steel companies to carry out to change the current unbalanced structure is not reasonable situation. To take advantage of the state has adopted a series of steel housing industrialization policies and measures, organization of scientific research institutions, design units and production companies worked closely to develop suitable for China's technical specifications and norms, through pilot and demonstration, promote the healthy development of steel housing industrialization . To further optimize the design of steel structures, promote the rational steel, low-carbon energy. In the steel structure to ensure the safety and use of functional premise, declining use of steel unit project, the development of new situation should become the consensus of steel profession.
