    1. Space steel structure buildings benefit from a large number of public buildings such as airports and railway stations, and develop rapidly. From 2010 to 2012, there are more than 500 new railway passenger stations in China. The corresponding steel consumption per platform is about 5,000 tons per year, which is more than 2.5 million tons per year, with an average annual steel consumption of about 800,000 tons. Among them, many representative terminal buildings and railway platforms are mostly built by member enterprises of the association, and have been awarded the "China Steel Structure Gold Award". In addition, member enterprises of the association construct more than 10 million square meters of heavy industrial plant every year; more than 1,000 space trusses and latticed shells are constructed, about 2.5 million square meters, using more than 70,000 tons of steel; 20 space trusses are constructed annually, about 600,000 square meters. Ten thousand square meters. In 2011, a total of 102417584 square meters of maintenance structure were built by the top 30 enterprises in the industry. In addition, suspension and membrane structures are still in the development stage, and the consumption is not large. It is expected that the annual growth rate will be 20%. The urbanization process of multi-storey and high-rise steel structures will promote the sustained growth of demand.

    For some high-rise buildings with large span, super high-rise and novel shape, we must get rid of the shackles of cost and cost by virtue of the advantages of steel bonds. Compared with reinforced concrete structure, steel structure can save 30% in the cost of foundation construction, and the utilization ratio of building area is 7% - 10% higher than that of concrete structure, and the construction period can be shortened by about 30%. According to the survey data, 13% of the steel structures under construction in 2011 were high-rise buildings. According to public statistics, in 2011, there were about 357 super high-rise buildings under construction over 150 meters in China, which increased in number and expanded in size compared with the same period last year. Among them, 43 (12%) are over 300 meters in height and 200,000 square meters in area; 6 (1.6%) are over 400 meters in height and 300,000 square meters in area; 3 (0.8%) are over 600 meters in height, and the highest international center of Ping An is 660 meters. By the end of 2012, there were more than 470 skyscrapers in China.

    At the same time, we should also note that there are many hidden dangers in skyscrapers, such as skyscraper fire rescue problems, high-rise shaking problems that have not been effectively solved so far, as well as non-environmental protection, non-low-carbon, high investment costs. In addition, the mentality of blindly striving for heights in construction planning has not been effectively curbed. In order to solve the above problems, the steel structure industry can carry out technological innovation to solve the problems of fire prevention, anti-corrosion and high-rise shaking of super high-rise buildings. It can also implement the "Green Energy Conservation Plan for Tall Buildings" to install energy-saving tools such as motion sensors on office lighting equipment, reducing energy use by 20%. These thermostats are then connected to the building's management system, which means that they can allow room temperature to rise or fall outside the standard comfort range before being registered in the room. The infrared sensor in the device means that the energy-saving process does not stop there. Once a person leaves the room, the room temperature starts to rise or fall again, allowing the heating or refrigeration system to rest until they are needed to work again.

    According to statistics, China accounts for six of the top ten skyscrapers in the world. According to "2011 China Skyscraper City" in the United States, the total number of similar skyscrapers. It is gratifying to the steel structure industry that most of China's super high-rise buildings adopt steel structure as the main structural form. Many top-ranking domestic steel structure enterprises undertake a lot of processing and construction tasks of super high-rise buildings. 3. According to the latest data of the National Bureau of Statistics, from January to November 2012, the national real estate industry opened. The development investment was 6477.2 billion yuan, a nominal increase of 16.7% over the same period of last year; the construction area of real estate development enterprises was 5566.58 million square meters, an increase of 13.3% over the same period of last year; the new construction area of houses was 1624.13 million square meters, a decrease of 7.2%; the completed area of houses was 677.06 million square meters, an increase of 14.1%. In November 2012, the prosperity index of real estate development was 9571 points, an increase of 115 points over October. In addition, the construction of guaranteed housing in 2012 also went smoothly.

    In January and October 2012, 722,000 new projects for affordable housing in cities and towns across the country were started, which exceeded the target for the whole year. Industry insiders expect the real estate industry to recover in 2013.
