Steel News Hainan: to develop steel structure, promote the sustainable development of green building

Hainan steel news: In the government work report this year, Prime Minister Li Keqiang, and actively promote green construction and building materials, to develop steel and prefabricated buildings. This is the first proposed the development of steel construction in the government work report. Steel is a green building technology, has to save human resources, improve production efficiency and ensure the quality of the advantages of function. In the field of construction steel is widely used, it will effectively promote green building sustainable development, promote industrial restructuring, and resolve steel overcapacity.

Our country is a big country of steel and big manufacturing country, the 2000s produced about 7 billion tons of steel, supporting the development of related industries, construction, transportation, shipbuilding and automotive. At present, China has qualified more than 3000 steel construction companies, employing about 500,000 people, the output value of about 500 billion yuan. In 2014, steel production reached 42 million tons, more than in Europe, America, Japan and the sum of the Australian production. However, the "five-second" period, the proportion of China's steel steel steel production accounts for only 5% to 6%, and in the towers, residential buildings and bridge structures, steel accounted for less than 1 %, far below the average level of 20% to 30% in developed countries. The main reason for this situation is the development of China's construction steel structures supporting policies to encourage the application inadequate, defective steel chain configuration, operation of the market mechanism is unreasonable, the lack of skilled steel structure design and other professional and technical personnel, technology and product support is insufficient, by a lack of iron and steel production or market-driven large-scale leading enterprises.

In order to solve the bottleneck problem of steel structure and industrial development, the Chinese Academy of Engineering has established "urban residential buildings and construction of new industrialization," "Steel housing industry consulting and research", "high-performance structural engineering Sustainable Development Strategy" and many more the advisory research projects, made a number of research results. At the same time, the 25 Chinese Academy of Engineering formed a "Fellow on in structural engineering and vigorously promote the use of steel is recommended."

To promote the rapid development of China's steel industry's sustainable. First, the state should strengthen top-level design, development co-coordinating body set up steel, integrated steel, construction, real estate, manufacturing equipment, building materials industry, the development of steel as an energy-saving strategy an important task to be the new industry policy support. Second, to promote steel housing in small towns, and new rural construction in high seismic intensity or resource-poor areas to promote the use of building materials. Third, we must go through Guantingbingzhuan and other productivity measures to support enterprises bigger and stronger, foster industrial clusters, industrial integration and enhance the competitiveness of enterprises, promote the steel industry. Finally, to strengthen technical innovation, take the road Cooperative, steel structure theory research, technology development and achievements of the formation mechanism.
