Not long ago, the National Development and Reform Commission made it clear that in the second half of the year, it will focus its efforts on energy conservation in key areas, conduct green building operations and urge all localities to formulate green building initiatives. Newly constructed green buildings of 50 million square meters will be built throughout the year.
Some experts estimate that by 2020, the scale of the industry driven by green building in China will exceed 1 trillion yuan, of which, the green building as a typical representative of the huge space for development of buildings. At the same time, the rise of steel structure buildings, especially steel structure houses, will digest hundreds of millions of tons of steel production capacity, which is an important way out for the steel industry in China.
Steel structure housing
Steel structure housing huge market space
Earlier this year, the National Development and Reform Commission and Ministry of Housing and Urban-Rural Development proposed to complete 1 billion square meters of green building during the "12th Five-Year Plan" period. By the end of 2015, 20% of new urban buildings will meet the green building standards. Subsequently, from the central to local have issued the implementation details of the development of green building.
"In developed countries and regions such as Europe, Australia and Japan, prefabricated steel structures account for more than 50% of the total, while steel structures in China make up less than 5% of the total. Compared to developed countries, the future market A lot of space. "Hangzhou Hangxiao Steel Co., Ltd. Vice President, Hangzhou Hang Xiao Architectural Design Co., Ltd. Yang Qiao Yang, general manager, said.
Under the impetus of the relevant government departments, China's steel structure housing has made great strides. Among them, Hangzhou Hsiao Steel Structure built in 2006 China's steel residential housing demonstration project - Wuhan Century Home has been put into use; construction area of nearly 1 million square meters Baotou Million County Metropolitan steel structure housing project has been completed, this is a Green building two stars standard design and construction of the national health demonstration project, is also the largest under construction in our country a new type of industrial steel structure housing district, by all sectors of the close attention.
Hundreds of millions of tons of steel is expected to find a new way
Just as our steel-framed houses are ready to go, its upstream industry, the steel industry, is struggling to find a way out for excess capacity.
"China's steel output ranked first in the world, with an annual output of 710 million tons of steel in 2011, when construction steel consumption was only 30 million tons, the proportion of insignificant 36 million units of affordable housing in China, if taken out Part of the construction of steel houses, with 30 kg -50 kg per square meter of steel, it will be an astronomical figure; if large-scale promotion in the commercial housing market, it will be a huge market! "China Construction Metal Structure Association Yao Bing believes that "steel and housing alliance is an important way out for the steel industry in China."
"Foreign construction steel accounts for 10% -30% of the steel output, with China's annual output of 700 million tons of steel, 10% is 70 million tons, but China's annual construction steel consumption was only 30 million tons (excluding reinforcement ) .While the United States, Japan, the countries that are popularized by steel structure construction, the amount of steel used has reached 30% of the steel output, "said Liu Wanzhong, secretary general of China Steel Structure Association.
What caused such a big gap? Liu Wanzhong believes that one of the reasons is that relevant government departments do not pay much attention to the heavy use of structural steel, there is no incentive policy. Now, this situation has changed dramatically. In April 2012, the Ministry of Finance and the Ministry of Housing and Urban-Rural Development jointly issued a green building subsidy policy of 45 yuan per square meter for two-star green buildings and 80 yuan per square meter for three-star green buildings. Industry experts calculate this sum: According to the allowance of 45 yuan per square meter count, government subsidies in the "second five" period will reach 45 billion yuan.
Housing protection to promote the focus
Hangxiao Steel Chairman Yin introduced single-wood, as the Ministry of Housing and Urban sentinel construction of the first fixed-point enterprises and steel structure of the first national industrial base of housing, Hangzhou Hsiao Steel has constructed more than 200 million square meters of steel structure residential industrialization projects, the annual processing Steel structure capacity has reached 1 million tons.
However, except for a few leading enterprises such as Hangxiao Steel Structure Co., Ltd., Baosteel Steel Structure Co., Ltd., Kunming Steel Structure Co., Ltd. and Laiwu Steel Co., Ltd., it is a common phenomenon that thousands of steel structure construction enterprises have not enough capacity to eat. A research report shows that China annually develops more than 1 billion square meters of residential area. However, the proportion of steel structure houses in China is less than 1%, far lower than that of Japan, the United States and France.
"From the perspective of the environment, the society lacks understanding of the large effective area of steel structure houses, fast construction speed, good quality and excellent overall construction cost. The government lacks the corresponding preferential policies. From the perspective of the industry, technical problems restrict its popularization and application, and steel structure houses One-time investment is high, the structure of building maintenance, complex floor connection technology, high technical requirements; from the developer to obtain the maximum economic benefits in the short term purpose, making low-carbon energy-saving technologies such as the enthusiasm of the new technology is not high, The formation of large-scale construction of the case, the cost is relatively high. "Yao Bing said.
The industry believes that another key area of steel housing promotion is the protection of housing projects. "Steel structure houses play a very important role in accelerating the process of housing industrialization, improving the safety performance and quality of residential buildings, changing residential production modes, promoting green building and energy conservation and emission reduction." With the deepening of social security housing construction, there is bound to be more Multi-steel structure enterprises into its development strategy. "Single silver wood said.
