　　At the 2015 Construction Steel Structure Industry Conference held recently, Party Guard, President of the Construction Steel Structure Branch of China Construction Metal Structure Association, made a special topic on how to adapt to the new normal, accelerate the development of my country's construction steel structure industry, and lead the industry's transformation and upgrading. Report. Below are excerpts from the report.

　　Ⅰ. Macro Background

　　Four industrial policies with the greatest impact on the steel structure industry in 2014 and their significance

　　1. On April 8, 2014, in order to promote green construction and building energy conservation and emission reduction, and promote the transformation and upgrading of the construction industry, the Ministry of Housing and Urban-Rural Development issued Jianshi [2014] No. 45 document, approving some steel structure enterprises to carry out pilot projects of general contracting for housing construction. Its significance It is to broaden the market access and contract scope of the steel structure as the main project of the industry enterprises, and is conducive to the industry to develop the green integrated building market and promote the process of building industrialization.

　　2. On May 15, 2014, the document "2014-2015 Action Plan for Energy Conservation, Emission Reduction and Low-Carbon Development" of the State Council issued [2014] No. 23 proposed "focusing on housing, focusing on building industrialization, and increasing support for the production of building parts" "Strengthen, promote the modernization of the construction industry", the exact meaning is to represent that the main force of construction parts is steel structure buildings, and the steel structure is completed in the factory as much as possible, which has positive significance for promoting the application of steel structure in the construction field.

　　3. On May 27, 2014, the "Green Building Evaluation Standard" was approved as a national standard, and it was implemented on January 1, marking the beginning of China's green building 2.0 era. "One of the two building systems required to be promoted is also the main direction of energy conservation and emission reduction in the building industry.

　　4. In October 2014, the Ministry of Housing and Urban-Rural Development's "Thirteenth Five-Year Plan for the Construction Industry", the steel structure industry and construction industry construction were compiled as separate chapters. Steel structure will become an important pillar of the construction industry. This means that we The following points are considered: the promotion of steel structure is an important means to promote the transformation and upgrading of the construction industry and realize the modernization of the construction industry; it is also an important guarantee for improving the seismic performance of buildings and reducing the losses caused by earthquake disasters; It is an important measure to promote the innovation of wall materials and promote the upgrading of the traditional building materials industry; it is an important carrier to develop a low-carbon economy and realize the requirements of green buildings.

　　Ⅱ. Current status of the industry

　　(1) Development of output value and capacity of construction steel structure industry in 2014

　　The technical management level and scientific and technological content have been continuously improved. Last year, we added 118 provincial and ministerial-level construction methods, and 11 new ones; 835 new patents; 56 new provincial and ministerial-level scientific and technological progress awards, and two new ones. . In terms of steel structure brand engineering construction, the seven skyscrapers over 500 meters under construction last year all use steel structures, and it is also the construction of our company here. They are Ping An International Financial Center, Wuhan Greenland, Shanghai Tower, Tianjin 117, Guangzhou East Tower, Tianjin Chow Tai Fook and China Zun projects.

　　On June 8, 2014, the results of the selection and award ceremony for Chinese contemporary architecture were announced, including: China Zun, Bird's Nest National Stadium, Shanghai Jinmao Tower, Taipei 101 Building, Guangzhou TV Tower, China World Trade Center Phase III, Shanghai Tower and other new buildings. A batch of "Chinese contemporary high-end buildings" are all buildings with steel structure as the main body. In addition, some steel structure buildings have also won many international awards: China Construction Steel Structure and the Guangzhou Opera House constructed by Zhejiang Jinggong have been selected by USA Today. Rated as "Top Ten Opera Houses in the World"; Sheraton Huzhou Hotel was awarded the 2014 Architectural "Oscar" Ampolis Skyscraper Award by Ampolis, the world's leading real estate research agency, and the Shenkeng Hotel constructed by Hangxiao steel structure was selected as the world's leading architectural wonder The hotel category in China is a miracle, and it is praised as a "world architectural wonder" by the National Geographic Channel of the United States; the "Chinese drum" constructed by Anhui Honglu has been certified by the headquarters of the Guinness World Records certification agency as the largest single drum in the world today. type building. Last year, the steel structure industry also participated in the polar construction of the national key project, which set a record: Shanghai Baosteel’s Antarctic Taishan Station in Antarctica faced the extreme low temperature of minus 40 degrees Celsius, extreme dryness, violent storms and snow, altitude sickness, UV damage and many other challenges. In just 45 days, the Chinese red lantern - Mount Taishan Station in Antarctica was "hanged" on the polar ice cap, setting a record for the shortest construction period in the polar region; Jiangsu Huning Steel Machinery participated in the National Astronomical Observatory's 500-meter-aperture spherical radio telescope in Guizhou (FAST) construction. The terrain surrounded by mountains and the millimeter-level precision requirements make the construction unprecedentedly difficult. Through technological innovation, a series of technical problems have been solved. To ensure the smooth progress of the construction project; at the same time, there are many companies participating in the construction of the main stadium and supporting facilities of the 2nd World Youth Olympic Games in 2014, and the final conclusion.

　　According to preliminary statistics of the industry in 2014, the amount of steel used in construction steel structures was more than 46 million tons, a year-on-year increase of 12%, accounting for 5.6% of crude steel output. There are 8 companies with a completed output value of more than 5 billion yuan; 9 companies; 25 companies with an output value of more than 2 billion yuan; 25 companies with a completed production capacity of more than 100,000 tons; 36 companies with a completed production capacity of more than 50,000 tons.

　　China Construction Steel Structure Co., Ltd. 980,000 tons, Anhui Honglu Steel Structure (Group) Co., Ltd. 850,000 tons, Zhejiang Southeast Grid Group Co., Ltd. 630,000 tons, Zhejiang Jinggong Steel Structure Group Co., Ltd. 590,000 tons, Jiangsu Huning Steel Machinery Co., Ltd. 450,000 tons. This is the top five manufacturers in the industry. From the above data, it can be found that the industry concentration is still not high. The top five enterprises have completed a production capacity of 350 tons, accounting for about 7.6% of the annual steel consumption for construction steel structures. Compared with the national crude steel output in 2014, which reached 822.7 million tons, a slight increase of 0.9% year-on-year, the other is the relevant data released by the National Bureau of Statistics, which shows that the national housing construction area in 2014 was 7.2 billion square meters. We conservatively estimate that the amount of construction steel is close to 4 100 million tons, construction steel accounts for nearly half of 48% of steel production, and our construction steel structure steel accounts for about 5.6% of steel production, accounting for about 10% of construction steel. The total output value of the overall construction industry was 17.67 trillion yuan, an increase of 10.2% over the previous year. In fact, this growth rate has slowed down significantly. The output value of our steel structure is 510 billion yuan, accounting for about 2.9% of the total output value of the construction industry. This ratio is very low, but on the other hand, it also shows that the development space of steel structure in the construction industry is still very large.

　　In 2014, the gross domestic product (GDP) was 63,646.3 billion yuan, calculated at comparable prices, an increase of 7.4% over the previous year. In 2014, the industry statistics completed more than 46 million tons of steel for construction steel structures, an increase of 12% over the previous year. %.

　　Last year, the application of steel structures in the construction field accounted for 87% of the overall housing construction completion, and the decline in the proportion of infrastructure accounted for 11.5%.

　　Judging from the distribution of completed projects in various economic regions, the eastern coastal region still accounts for more than half of the 55.3%, the northeast region still accounts for a relatively low proportion of 8.9%, the central and western regions have developed, the western region accounts for 19.4%, and the central region accounts for 16.4% %. This is in line with the economic development situation of our country.

　　(2) The specific situation of the development of scientific and technological progress in the construction steel structure industry in 2014

　　Member companies participating in scientific and technological achievements have won two second prizes of the National Science and Technology Progress Award. One is "Key Construction Technology Innovation and Application of 100-Story High-rise Building" participated by China Construction Steel Structure and other companies, and the other is "Key Technology and Engineering Application of Large-span Steel Structure Fire Prevention and Corrosion" participated by Zhejiang Seiko and Shanghai Baoye. There are also a number of projects that have won provincial and ministerial demonstration awards.

　　(3) The specific situation of standardization construction of building steel structure industry in 2014

　　Last year, there were 27 national standards compiled and participated in by the industry, and 60 provincial and ministerial industry standards. China Construction Steel Structure edited the National Standard Atlas of "Steel Structure Connection Construction Diagram (Welded Connection)" last year; in addition, last year, the association led the application to edit the JGJ industry standards "Technical Specifications for Metal Sandwich Panels" and "Technical Specifications for Stainless Steel Pipes for Construction". The project was approved; the Hong Kong and Macau Association jointly published the "EU Standard Steel Material Equivalent Design Application"; the Macau Association translated the "Steel Structure Design Manual" of the British Steel Structure Society. Officially approved and released by the Hubei Provincial Department of Housing and Urban-Rural Development, and edited by China Construction Steel Structure Co., Ltd., "Technical Regulations for Construction Safety Protection Facilities for Steel Structures in Construction Engineering" (DB42/T990-2014), which will be implemented on September 1. It is the best local standard in the field of steel structure construction safety protection in my country; Anhui Province "Technical Regulations for High-rise Steel Structure Housing", edited by Anhui Fuhuang Steel Structure Co., Ltd. and Honglu Steel Structure (Group) Co., Ltd., July 2014 It was implemented on January 1, and it is also the national standard for high-rise residential buildings with steel structures. The member companies of the association have also compiled many corporate standards, such as the "China Construction Steel Structure Manufacture Safety Standard Atlas" issued by China Construction Steel Structure, the "Light Steel Metal Profiled Steel Plate Building Structure" issued by Hangxiao Steel Structure, and the flooding collection. Edges, etc. standard atlas.

　　(4) For the work of construction industrialization, at the end of last year, the Association took the lead in completing the acceptance of the project results of the Science and Technology Plan Project of the Ministry of Housing and Urban-Rural Development, "Research on the Promotion of Industrialization of Steel Structure Housing".

　　This is the first ministerial-level research project for steel structure housing in my country. Academician Nie Jianguo of the Chinese Academy of Engineering serves as the leader of the expert acceptance team. At the same time, a number of steel structure residential projects have won the National Comfortable Housing Project. Qianjiang Century City Talent Special Housing Project Phase I and Bid Section II recently won the honor of "National Demonstration Project of Land-Saving, Energy-Saving, Environmental-Friendly Housing National Well-being" by the Ministry of Housing and Urban-Rural Development; Wanjun Metropolis successfully passed the National Health Comprehensive evaluation of residential demonstration projects. At the same time, a number of enterprises are actively promoting the industrialization of steel structure housing; the first high-rise steel structure housing in Beijing built by the Steel Structure Branch of Shougang Construction Group will only take 75 days, and the 20-storey Mentougou Lead Wire Factory will rent 1 The "skeleton" of the No. 1 building rose from the ground. The project is expected to be ready for occupancy in May this year, and can meet the housing needs of 320 families. Baosteel actively promotes the construction of housing industrialization bases. Handebon Building Materials has successfully passed the certification of "New Wall Material Products in Zhejiang Province", China Construction Steel Structure was awarded the title of "Shenzhen Housing Industrialization Demonstration Base"; Southeast Grid was awarded "Zhejiang Province The title of “Demonstration Enterprise for Promoting New Building Industrialization”; the industrialization project of modular and prefabricated new high-rise residential main structure system and energy-saving exterior wall system declared by Jinggong Green Building Integrated Building System Industry Co., Ltd. won the investment of 10 million yuan from the central budget of the National Development and Reform Commission. grant.

　　(5) In terms of overseas business, in 2014, the overseas market of member companies completed a production capacity of more than 800,000 tons, with an output value of more than 20 billion (exports of metal plates exceeded 2.5 billion yuan), which is a leap forward compared to 2013. Benefit from the promotion of the new "One Belt, One Road" strategy.

　　Explosive growth of overseas orders: Baosteel Steel Structure won the steel structure engineering orders for two projects of American National Oil Well; Zhejiang Hangxiao Steel Structure Co., Ltd. undertook the Georgia Hualing International Trade Plaza Project, Singapore Shipyard Phase II Steel Structure Installation Project, etc.; Seiko Steel Structure Co., Ltd.

It is the largest order for the export of sheet metal in the industry; Zhejiang Southeast Grid Co., Ltd. and the Venezuelan Motherland Development Fund 2000 signed the Venezuelan Conference Center and Parking Building Project, with a total amount of about 1.069 billion yuan. The project is the Ministry of Housing and Urban-Rural Development. After the issuance of the first-class qualification for general contracting of steel structure for housing construction, the first overseas general contracting project won by using this qualification. Overseas projects under construction have performed well, and Chinese brands are well-known all over the world: Abu Dhabi Airport, Algeria Grand Mosque, National Bank of Kuwait and other projects undertaken by China Construction Steel Construction are progressing smoothly; China Construction Eighth Bureau successfully completed the largest single-scale comprehensive sports center project in Africa - Congo (Brazzaville) Brazzaville Sports Zongxin project (10,000 tons).

　　(6) The general contracting pilot work has achieved gratifying results for one year, which is mainly reflected in the improvement of the organization, the strengthening of team building, and the standardization of the market.

　　Since April 2014, steel structure enterprises have carried out the pilot project of general contracting of housing construction projects, under the guidance of the Ministry of Housing and Urban-Rural Development, local competent departments and industry associations, pilot steel structure enterprises have seized opportunities, pioneered and innovated, and strengthened their own capacity building. While its own development and growth, it has promoted the transformation, upgrading and healthy development of the industry.

　　Each enterprise sets up a general contracting team (general contracting department, green building business department), forms a general contracting management structure, exercises general contracting functions, and establishes and improves the relevant management system of general project contracting. Each enterprise has supplemented more than 100 senior talents such as first-level construction engineers and senior engineers, and completed nearly 1,000 professionals in design, civil engineering, electromechanical, decoration, and curtain wall. The wages of working migrant workers have been better guaranteed than ever before. The capital increase and capital increase of the joint-stock enterprises have promoted the investment in science and technology of various enterprises. The capital increase and financing of the enterprises reached 2.83 billion yuan, which increased the financial capital for the research and development and expansion of the enterprise. Enterprises generally increase investment in scientific and technological research and development and trial production of construction products, and scientific and technological progress has reached a new level.

　　The growth rate of market development, the business volume of each company has been enlarged to varying degrees, and actively develop the housing construction market with steel structure as the main project. After one year of implementation, each company has undertaken a total of 52 general contracting projects with a contract value of more than 7 billion yuan . It is relatively obvious to open up overseas markets. In the general contracting market of steel structure housing construction projects, Zhejiang Southeast Grid Co., Ltd. and Beijing Duowei United Group Co., Ltd. have undertaken projects in Venezuela, Singapore and other countries; among which, the contract value of the Venezuelan Conference Center project reached 1.07 billion Yuan. A typical project case The Southeast Grid took 160 days to build a 100,000-square-meter school, an architectural miracle, Mianyang Fuller International School. It is the country's first fully assembled steel structure earthquake-resistant school.
