Guangzhou Steel News: Steel imagination
By 2014, China's crude steel production 823 million tons, accounting for about half of the world, 70.69% capacity utilization. Faced with the pressure of excess capacity, many steel enterprises to expand the domestic market lies in the steel construction.
Developed countries like the United States, Japan and so very focused on the implementation and use of steel construction, steel steel construction accounted for more than 60% of steel production, steel area accounted for more than 40% of total construction area.
But China Steel processing, production profiles only 6 percent of steel production, steel area only accounted for 1% of the construction area. Due to high cost, because of poor fire resistance, steel has not been widely recognized.
New "green building evaluation norms" in this year officially implemented, the current building housing the Ministry and other departments hope to further promote the use of steel shelter, the new construction will also promote urbanization carry out domestic steel market and steel shelter, steel market space gradually open.
Prospects
Steel construction with a high degree of industrialization of production, construction project management and construction and security, to help resolve the overcapacity in steel, iron and steel resources to promote recycling, reduce construction waste, to achieve a win-win economic and energy saving and many other advantages.
In recent years, with the national implementation of green building, promoting energy conservation efforts to increase the construction industry to accelerate the pace of transformation. April 2012, the Ministry of Finance, Ministry of urban and rural housing construction have jointly issued "Opinions on accelerating Chinese green building to carry out" green construction steel was included in the ranks, it has also been given appropriate incentives.
After 2008, in promoting the Beijing Olympic Games, the domestic steel construction boom emerged, built a large number of steel stadiums, airports, railway stations and high-level construction. But overall, the general home market China, the concrete structure which still accounts for more than 90%.
Preliminary estimates, in 2014 the national housing new construction area of nearly 180,000 square meters, for example, if steel consumption per square meter of 100 kg calculated as steel shelter, the proportion of steel shelter 1% to 10% if the annual increase 16.2 million tons of steel demand, reducing concrete occupy 40 percent of the total amount of municipal solid waste and other garbage build up to 400 million tons.
Implementation problems
In front of the huge market potential and the pressure of overcapacity, some steel companies began to expand related businesses plan their steel company, the implementation of seismic, environmental protection, construction cycle short steel construction. However, compared with a variety of good expectations the industry level, the social level and the national level, domestic steel construction in particular to carry out the civil construction field power is obviously insufficient to carry out slow.
High cost is the primary problem. Hou trillion new introduction, steel shelter than concrete shelter direct cost per square meter is higher 200,400 yuan, while keeping costs down, but the quality of construction is still no obvious advantage.
Especially in the case of live experience is not very good, developers and consumers less active. Many developers will be low for the cost of steel, hoping to "spend money to buy a cotton-padded jacket Down", resulting in some of the low quality of construction steel, the steel structure for the implementation of negative effects.
Industrial chain is not mature enough. Steel construction, involving supporting beams, walls and floors, doors, windows and other structures and components, but the market has not yet formed scale effects, and effective convergence yet to be standardized. Steel construction "fast, and the province, and beautiful, and comfortable" features on the market yet effective flash.
March 2015, Department of Housing held a special meeting to once again wish to implement Guangzhou Steel, currently still being worked out concrete measures.
Way Out
Overcapacity in the steel and energy savings in the background, to carry out the construction of the steel structure is the trend.
Hou Zhao new that, in the high-rise steel construction 100 meters above has absolutely competitive. Steel's future is more prevalent in the lower to the construction.
To do this, you can take the "detour to carry out" strategy, led by local government, office buildings, school buildings, hospitals, affordable housing and other government investment, regular and relatively simple to use common construction steel.
Once the construction of steel with good function put into use, will play an exemplary role in society as a whole. After improved in terms of market share, social influence and customer acceptance, etc., and then gradually focus to residential towers built on class.
At the same time, you can boot using the commercial development of steel structures by increasing the preferential policies. For example, the right to further improve the steel weight of green building ratings. You can also let developers select the volume of steel to improve development rates and get tax breaks, which will greatly enhance the enthusiasm of the market for steel use.
The industry also suggested that countries could use central finance capital fund set up steel structure implementation, steel structure technology elements to support research and development, accelerate technological progress, to reach more excellent features to further reduce costs.
CISA vice chairman said that if the country given the necessary policy support, the future construction of the steel has a very broad prospects for implementation. Guangzhou Steel
