On the development of China's steel market
Guangzhou Steel News: adoption and the company's in-depth exchanges on the development of China's steel market to do a simple sort, believe that steel market has immediate practical significance to promote China's green building and construction industrialization, promotion of traditional construction upgrades.
Steel Introduction
Our steel industry is an emerging industry, construction steel and hot rolled steel sheet refers to, cold-formed or welded sections (I-beam, H-shaped steel, pressure plate, etc.) by connecting pieces (bolts, high strength bolts, etc.) connection It can withstand a load transfer structure in the form of load, with high strength, light weight, good seismic performance, short construction period, the high degree of industrialization, less environmental pollution and other advantages. Steel is building a new type of energy-saving and environmental protection, cycle efficiency using the highest architectural structure, known as the 21st century "green building", meet the requirements of national development due to energy-saving building and sustained and healthy economic development, by the national We attach great importance to being listed as one of the top ten new technologies the Ministry of construction. At present, the steel construction is widely used in sports stadiums, terminals, exhibition halls, supermarkets, bridges, factories, commercial buildings, residential, covering architectural design, structural design and deepening of steel components manufacturing, installation and construction of the entire process. In developed countries, the steel structure reasonable, widely used in construction engineering field.
Advantage Steel Buildings
(1) quick installation: simple steel production, usually manufactured in specialized factories, the scene just installed fasteners and bolts, short construction period. This facilitates the return of investors' capital, but also saves labor costs.
(2) Seismic wind: steel ductility, plastic deformation ability, excellent seismic performance of wind for the building can take advantage of this feature, greatly improve the stability of the building. In particular, in the event of earthquakes, typhoons and other disasters in the case of steel structure can effectively avoid the collapse of the buildings destroyed.
(3) Durable: Steel itself after processing and surface treatment, corrosion resistance and durability. This makes the service compared to other steel structures and other wooden structures longer.
(4) Energy Saving: compared to concrete construction, steel construction materials mainly for steel, mainly for the installation of the construction site, work less, live little dust, sewage, noise, environmental pollution and reduce construction waste generated. And during building demolition, most engineered materials can be recycled or degraded.
(5) plasticity, widely used: steel member can be made into various shapes or combinations of structure, design flexibility, such as the "Bird's Nest", "Water Cube" and other buildings modeling is fully demonstrated the plasticity characteristics of steel; steel It can be widely used in industrial plants, high-rise and high-rise building, residential, large public buildings, airport and other areas.
Industry development
Since the reform and opening up, especially after the 1990s, with the development of national economy and the steel industry by leaps and bounds, China's crude steel production increased from 272 million tons in 2004 to 823 million tons in 2014, from the government "restrictions and rational use of steel to the development of steel" policy guidance and support from major projects, landmark building using steel to the widespread use of steel, the steel industry has developed rapidly.
With the Development and Reform Commission, the Ministry of Housing issued a "notice of green building program of action", requiring new buildings 1 billion square meters of green "five-second" period. By the end of 2015, 20% of urban new buildings achieve green building standards. Among them, the steel building is becoming one of the development of green building. The growing importance of environmental protection, green, energy-efficient buildings will be the focus of future urban construction. Under the impetus of urbanization construction, steel construction of green market will be very large, an estimated tens of thousands of yuan huge market is accelerating the formation.
(1) investment in infrastructure to promote market demand for steel
In recent years, Chinese investment in infrastructure construction has maintained rapid growth, infrastructure investment in fixed assets increased from 2004 to 17,102.42 billion yuan in 2014 to 112,174.48 million, 10 years CAGR of 20.69%.
Chinese urban infrastructure construction debts more, a large gap. Traffic congestion is getting worse. Inadequate water supply, drainage behind. City vaporization rate. Long-term energy supply shortage. Transport, especially rail transport capacity seriously inadequate. These are the bottleneck restricting economic development, and therefore China's infrastructure construction investment will continue to maintain a high growth rate.
Building infrastructure will contribute directly to the market demand for steel. For example: railways, roads and bridges are made of steel; airport terminals, new and expansion projects and railway station waiting hall platform is also increasing; all kinds of public works projects will also be a large number of steel structure. In addition, with the rise of China's central and western economy, the implementation of the national "along the way" strategy are development of steel industry provides a good opportunity.
(2) the proportion of Chinese construction steel has much room for improvement
In the steel industry mature countries, the proportion of steel in building structures in general more than 40%, the United States accounted for steel construction in most years above 40% in 1999 to reach 56%; Japan in the 1990s steel construction accounted for 39%. UK new construction is more than 90% of steel. According to the China Steel Association, in 2012 China accounted for using steel construction is only 6%.
The rapid development of the steel industry generally 20--25 years, then entered a mature and stable phase, when the proportion of total steel production in steel production is about 20% -30%. The rapid development of US Steel for 1953-1975 years 1955-1975 in Japan, lasts about 20--25 years. After entering the maturity, the peak US steel production was 50 million tons, steel output corresponding to about 1.1 million tons, accounting for 45%, followed by the ratio decreased, maintained at about 20-30%; steel production in Japan stabilized at the level of 25 million tons of annual steel production stabilized at about 100 million tons, accounting for about 25%.
Since 2001, China's steel industry has formally entered a rapid development period, the average annual growth rate of over 20% in 2008 by the financial crisis has slowed down, and then maintain about 10% level, but the steel industry is still in the progressive stage of development, at present the proportion of crude steel production accounted for only 5.6%.
(3) rising labor costs and policy support to increase the proportion will increase to boost domestic steel construction
① Chinese labor costs rise very quickly in the future this trend will intensify, while excess capacity due to a prolonged slump in steel prices difficult to reverse in the short term, steel prices steel prices difficult. According to data analysis, China Construction Cost Information Network, the future construction workers' wages upward trend will probably be more intense, partly because structural changes in the labor force, on the other hand because today's young people in the construction trades willingness to continue to decline. Currently steel construction than traditional building total cost of about 5% to 10% higher per square meter (about traditional cost 2000 yuan / m2, steel was up about 100 to 200 yuan / m2), the future, as labor costs continue improved traditional building cost advantage will be eliminated.
② 2014 in mid-March, the State Council issued the "National new urbanization plan (2014-2020)", which refers to the proportion of urban green new construction from 2012 to 2020, a 2% increase 50%. In 2012 promulgated the "Opinions on Accelerating the implementation of green building to promote development", the goal is simply raised to 30%, the extent of the current government emphasis on green building has increased significantly.
Future Trends
Steel for its seismic, wind resistance, durability, environmental protection, the advantages of fast growing range of applications in our country. The late 1990s, with the development of the national economy and the steel industry by leaps and bounds, the domestic steel enterprises by learning and absorbing foreign advanced level, the steel industry has never had a thriving scene.
As the state has increased investment in infrastructure, construction steel will be widely applied to energy projects, infrastructure, high-rise residential areas, subway and light rail projects, overpasses, viaducts and other urban public facilities will be more and more steel structure, steel structure and broad prospects. Moreover, with the popularity of the green, green building concept, steel residential design specifications and related technology matures, steel construction scale will be improved due to China's steel prices, labor costs are far lower than the international level, is bound to Strut structure integrated residential development, the promotion of a positive impact.
Overall, the integrated current domestic situation, as well as policies to promote the future steel market has great room for development
