Steel Product Description
Steel is a steel-based construction structure, it is one of the main structural types of engineering and construction, and one of the more common modern construction engineering structural form.
Fundamental characteristic of the steel is a high strength, light weight, good rigidity, strong deformation, it is particularly suitable for the construction of large-span and ultra-high, super-heavy construction material. In addition, homogeneous and isotropic steel is good, is the ideal elastomer best serves the fundamental assumes general engineering mechanics; material ductility, toughness, and can have large deformation, can well withstand dynamic loads; construction period is short; its high degree of industrialization, can be a high degree of mechanization of specialized production.
Now, China's major steel industry include: 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 entire steel downstream industries, the amount of housing construction accounted for more than half of steel; various non-standard steel structures and machinery and equipment used together accounted for approaching half. According Steel Association in 2009's survey points to the steel calculation: construction structures (factories, more high-level, public construction) to 5.815 million tons, accounting for using the percentage of 54%. 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 amount of construction steel in the plant topped the 2,902,000 tons, accounting for 49 percent, followed by the use of public construction, high-rise steel structure, multi-steel structure, the proportion respectively: 21%, 17%, 13% .

Steel Product main features
Seismic Wind: good ductility of steel, plastic deformation ability, excellent seismic performance wind, for the construction can be fully demonstrated the characteristics, greatly improving the stability of construction. In particular, in the event of earthquakes, typhoons and other disasters cases, steel can be useful to prevent the collapse of the construction material destruction.
Durable: Steel itself after processing and appearance processing, corrosion resistance and durability. This makes steel structures for longer than any other wooden structure to perform labor time.
Means fast: the fundamental components of steel produced in the factory, the scene usually only be means of fasteners and bolts, construction period is shorter. This promoted 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 material used is steel. Moreover, in the construction was removed, large some materials can be reused or degradation, reducing pollution. Guangzhou Steel

Status Quo domestic steel occupations
In recent years, significant strengths of steel brought prosperity 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 research MCC General Hospital was established. In June 2008, the construction of steel structures Ministry of Education 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, which advances the steel structure design, construction quality; enhance professional standards and procedures. From the steel company's growth rate and the construction level, the large number of powerful steel company undertook the production of large steel elements and means domestic projects, new technologies, new construction methods, new equipment after another, also reached the level of construction equipment international advanced level; steel supporting commodity complete, processing equipment production plant carried out rapidly, to better meet the needs of steel professional conduct. Now, China's output of steel structures, industrial planning, market development are among the first in the world to use, equipment manufacturing and equipment technology to reach the world advanced level.
Since vocational and technical demanding, less access conditions, uneven texture steel company, occupational fierce competition. Now, the number of the country's steel company over a million, but with a certain plan, the company has fixed production sites in around 5000, with a level of professional qualification steel company more than 400, the annual processing capacity of 50,000 tons or more of large-scale Steel company has nearly 50. The leading steel company commodity quality, leading occupation carried out direction, good at absorbing and digesting today's leading international technological achievements, in some technical areas now reach or exceed the international advanced level.
Geographical spread, the country's steel industry has shown a spread unevenly, 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, spread less industrial Midwest, industrial level is not high. Looking at the country, company a lot, but the plan in terms of quantity, influential, strong brand company much. Although China is a big country of steel, but not the steel powerhouse, with iron and steel occupation exists overcapacity, a serious oversupply in the domestic market of contradictions, future steel professional conduct required merit.
Steel construction: the Golden Gate Bridge
Now the industrial policy support
Our 30 years of reform and opening up and economic development, has been undertaken to create a very favorable environment for the use of steel system. "2010-2015 Steel" Twelfth Five Year Plan "policy recommendations (draft)," pointed out:
1, strive to be included in the national steel industry, "second Five Year Plan" in strategic emerging industries, to gain support of national ministries and relevant policies. Important prominent towers, construction industry in the national economy growth, output, output value proportion prominence in professions steel housing, the potential market and non-standard steel bridge, complete sets of equipment and production technologies for independent innovation, so that China's steel industry in a dominant position at home and abroad, truly become strategic emerging industries.
2, increase the standard steel design standards related to the revision of the investment, the progress of our housing construction, bridge, tower mast, standard steel containers, progressive design life and meet environmental green, low-carbon and circular economy, promote self-reliance innovation and China's modernization construction of more scientific, civilized.
3, to promote the development and use 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, including those with refractory weathering resistance, low temperature, resistance to seawater corrosion resistance, chemical medium corrosion function of steel for the construction of the bridge, tower mast, container, marine equipment manufacturing supply upgrading and updating material. Better and more fully demonstrated rational use of resources, joint referral steel occupational independent innovation, creativity and scientific and technological progress.
4, continue to thoroughly build steel production industry, so that steel production 25 million tons in 2010, based on more than double by 2015 to reach 5000-6500 tons. Steel production in the country and strive to reach 10% of crude steel production policy. Steel production company integrated technology to reach 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, steel wind power, etc.).
2, traffic engineering will be added in the bridge, railway bridges are made of steel, with steel highway bridges in recent years has become a trend to carry out, the Beijing-Shanghai high-speed, cross-sea, across the bridge using steel bridge, Expressway 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, the amount of steel used in municipal construction will add, subway and light rail projects, urban overpass, viaduct, environmental engineering, urban public facilities and temporary housing etc increasingly using steel.
4, will add steel housing. State-sponsored land-efficient housing construction, the relevant steel housing design standards and supporting technologies, materials simply possess. Now only a few million square meters of steel structure housing, developed countries are to reach the 40 to 50 percent. When completed in China each year to build 600 million square meters of residential townships are 5% with steel, according to a multi-layer, high-rise construction of an average of 50 kg / m steel design, steel consumption will reach 1.5 million tons per year. It has not been built with steel rural counted.
"Thirteen Five" period, adjusted according to the national industrial policy, to support some of the low energy points, planned management of large steel companies, improve the quality of all occupation undertaken to meet market demand, and gradually filtering some irregular, shoddy, low efficiency High energy company, further occupation of China's steel market standard order. To carry out scientific research and technological innovation activities in steel occupations, the relevant state departments should introduce appropriate industrial policies, invest the necessary funds to develop the use of steel structures to support it, to change the current steel company to carry out the imbalance, structural Situation unreasonable. 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 produced in close cooperation, development of technical standards and standards suited to China's national conditions, through pilot and demonstration, promote steel housing industry healthy development. To further optimize the design of steel structures, steel initiate reasonable, low-carbon energy. In ensuring the safety and use of steel function premise, it continues to reduce the amount of steel used to engineering units, and this trend should become a consensus to launch a new career in the steel.
