Current situation of steel structure industry in China

Low industrial concentration

At present, there are 143 steel structure (special) grade I construction enterprises in China, plus 427 steel structure additional grade I qualification enterprises, with a total of 570 steel structure grade I qualification enterprises!Recent statistics of Shanghai metal structure association show that in the member units of Shanghai metal structure industry association, there are 380 steel structure manufacturing and installation enterprises (including some other provinces and cities), with an annual output of 3.6 million tons, and it is said that only Shanghai registered steel structure construction enterprises reached 500 or 600.The development of steel structure industry is like the spring and autumn period and warring states period in the history of China. Steel structure enterprises have reached thousands from dozens, but the annual output of 100,000 tons of enterprises is very few, forming a contrast between the rapid development of the market and the increasingly low concentration of the industry.

The main reason is that the entry threshold of the steel structure industry is low, whether it is capital or technical requirements are not too high.

Low industrial concentration is the direct consequences of excessive competition, in 2005, the steel structure enterprise with an average of 5%, in addition to the chongqing steel, pipe truss structure and complex, the difficulty in construction of big project profit space is larger, such as portal rigid frame light steel structure due to the fierce competition, the profit space is generally lower, so just had some companies to bid and steal industrial waste material, so we have a three-dimensional "white paper" sensationalism.

However, it is gratifying to note that in the 13.51 million tons of steel structure processing capacity calculated by the steel structure association in 2005, the processing capacity of the top five steel structure enterprises has exceeded 1 million tons, and the annual processing capacity of the top ten enterprises is basically above 100,000 tons.

Brand chaining

In the face of fierce market competition, in order to reduce the cost of engineering long-distance processing, some large steel enterprises in the development to a certain degree gradually implement low-cost expansion, they started throwing up across the country, such as hangzhou xiao in anhui, shandong, henan, jiangxi, guangdong, hebei branch offices and other places, seiko in zhejiang, anhui, Beijing, hubei and other places are equipped with steel structure processing base, southeast of the rack based in zhejiang, chengdu, tianjin and guangzhou, and architecture as a center of radiation processing network throughout the country, in the steel structure and its main business, at the same time, the establishment of fujian association of foreign languages and basesSoutheast is the tentacles extend to the development of the steel structure of the relevant industries and other industries, the stretched industrial chain, have established real estate companies, zhejiang southeast zhejiang southeast of sheet metal co., LTD., zhejiang and hangzhou xiaoshan hospital studies system building materials co., LTD., but to remind chaining layout may lead to problems, like xuzhou flying quality accident in Inner Mongolia xinfeng power plant and the southeast of guangzhou university town construction accident is worth thinking.

Setting up overseas markets

The domestic amount of steel used in the light steel plant is generally 300-400kg/m2, and the cost is 300-400 yuan/m2. The processing and installation cost of light steel components is 5000-5500 yuan/ton, of which the processing cost of steel components is 1000 yuan, the installation cost is 350-400 yuan/ton, and the material cost is 3,000-4,000 yuan/ton.However, the processing and installation cost of steel components in Japan, Europe and the United States is more than 10,000 yuan/ton, so some domestic steel structure enterprises with strength began to extend their tentacles overseas.

As early as the day after the devastating earthquake that hit the Algerian capital in 2003, a private enterprise in shaoxing undertook the construction of the steel structure of the Algerian airport without hesitation while other international companies were leaving.This "bold" private enterprise is zhejiang jinggong steel structure co., LTD., which is also the first overseas construction steel structure enterprise in China.

Boost strong brand with strong technology

At present, steel structure enterprises need to solve many high-level technical problems to improve their core competitiveness.Fortunately, many steel structure enterprises have attached great importance to science and technology, such as southeast steel structure enterprises and zhejiang university, tsinghua university and other famous universities cooperation, and such as baoye construction and tongji university cooperation, the establishment of tongji robot company, will be advanced hydraulic technology for steel structure construction.For the advanced and representative projects, domestic steel structure enterprises are also gradually breaking through, such as the large span space grid steel structure is the emerging trend of steel structure development, many aspects are still blank.Therefore, national Treasury Department specially funded treasure smelting construction make the comprehensive development of the project, among them, including the large span spatial grid steel structure design software research and development, the large span spatial grid steel structure installation technology research, large-span spatial grid steel structure production technology research, the structure of the large span steel space grid structures without purlin combination pressure plate research and development, the large span spatial grid steel structure design, the cast-steel joints, welding, ultrasonic testing six research, etc.At present, the subject has reached the conclusion requirements.The steel structure project of nanjing Olympic sports center built by baoye construction co., ltd. with its related technologies is the longest in the world with a span of 360 meters.The project won Shanghai king kong award and China gold medal of steel structure, and brought considerable market share to baoye construction in the construction of large-scale exhibition and large-scale sports venues, which laid a solid foundation for the sustainable development of baoye construction steel structure.Zhejiang hangxiao focus on r&d, the company in 1997 and zhejiang university jointly established the "zhejiang hangxiao research and development center", and fuzhou university, tongji university, xian building university of science and technology such as universities, for the some topics in the field of steel structure, experimental study has been developed to form multiple set of enterprise standards, has applied for national patent item 24.

Fuhuang steel structure has established long-term "industry-university-research" and technical cooperation relations with zhejiang university, tongji university, hefei university of technology, anhui building materials industrial design institute, shenyang metal materials research institute and other colleges and research institutes.In recent years, together with Shanghai tongji university, we have organized "anhui fuhuang steel structural engineering design and research institute" and "Shanghai tongji fuhuang steel structural technology research center for multi-high-rise buildings".In line with the development of The Times, representative technological breakthroughs will effectively promote the development of China's steel structure industry and enterprises.

Upstream and downstream mutual penetration, brand three - dimensional trend prominent

Masteel, baosteel and laiwu steel, relying on h-beam and plate and strip, gradually implement the extension to the steel structure industry.Baosteel group corporation to do big, do strong, baosteel steel deep processing industry will be ranked the chongqing steel, high-frequency welding h-beam, light steel and cold bend section steel industry "leader" of Shanghai crown, steel structure co., LTD., Shanghai chase steel structure co., LTD., treasure to produce steel structure co., LTD., Shanghai process units such as the ranks of baosteel industrial development co., LTD., with the aid of "baosteel" brand advantage, the new round of development of baosteel steel structure industry has laid a good foundation.It is worth mentioning that masteel and laiwu steel took promoting the development of steel structure industry as a breakthrough from the perspective of large industry in the early stage of h-beam development and promotion, and also did a lot of work in residential steel structure in recent years.In February this year, shougang shoumetallurgical machinery shi branch, shoumetallurgical junction branch and the original shoujian metal structure plant implement integration, the establishment of shoujian steel structure branch, in less than a year to complete the settlement income of 363 million yuan, the profit of 65.76 million yuan.Successively undertook the tonghui river crossing, feng north road, the capital airport light rail bridge lize bridge, zhangjiakou three Ma Fang bridge, tianjin CiHaiQiao, Beijing central south area (A) the sun B1S4 HuaJun new yunnan crowne plaza, Beijing international center, the CBD ZongCan communications office buildings reconstruction, CCTV new site television cultural center main stage theatre lifting platform, Beijing sevenstar Morgan square of 24000 tons of steel structure production tasks, lit the shougang steel structure brand.

Henan rongtong, shandong mastercard by virtue of the material circulation channel advantage of their business scope also began to steel structure processing progress, hang xiao, seiko to upstream materials, fuhuang attempts to steel structure processing machinery industry all show us the steel structure enterprise multiple brand strategy.
