A model of building energy efficiency: As a new industry in my country's construction field, steel structure has received great attention from the country and is listed as one of the top ten new technologies of the Ministry of Construction. Large room for development: At present, the amount of steel structure in my country is small, and the output of steel structure in developed countries accounts for more than 10% of crude steel. my country has only about 4%, and there is huge room for it. As steel structure buildings have the characteristics of environmental protection and energy saving, good earthquake resistance, light weight, and high strength, my country attaches great importance to the development of the steel structure industry, and has issued a series of policies to promote the development of the steel structure industry and increase the degree of industry concentration.

Steel structure demand side: The application of steel structure in construction accounts for 55% of the total operation of steel structure. In the steel structure of construction, factory buildings account for 51% and high-rise buildings account for 20%. Therefore, my country's long-term industrialization and urbanization are the cornerstones of industry development. Industrial transfer favors the construction of steel structure workshops: Industrial upgrading and industrial regional transfer have brought about an increase in the demand for steel structure workshops, which is beneficial to the light steel industry used in various industrial buildings, warehouses, supermarkets, and multi-storey steel structures. Consumption upgrades and infrastructure investment are good for steel structure construction: consumption upgrades have brought about the construction of cultural and sports centers, stadiums, etc., and large-scale infrastructure investment has brought about the construction of steel structure infrastructure projects such as subways, railway stations, and airports.

Industry competition pattern: In 2009, the number of steel structure processing enterprises rose to more than 3000, and the competition within the industry was fierce. In terms of geographical distribution, Shanghai, Zhejiang, and Jiangsu are relatively concentrated, and the top five provinces and cities together account for more than 1/3 of the national steel structure output. At present, there are three main types of steel structure enterprises: state-owned large and medium-sized enterprises, formal private enterprises, and small steel structure enterprises. Based on our estimated steel structure output in 2009, the market share of the top 20 steel structure companies is 14%, and the market share of the top 40 must be less than 28%. The industry concentration needs to be improved in the future.

Comparison of steel structure enterprises: Jinggong steel structure: industry leader, all-round development, 6 major industrial bases have a production capacity of 500,000. The company develops light steel structure, space steel and heavy steel structure in parallel. The company has a leading position in heavy steel and space steel. The major projects are mainly heavy steel and space steel. 1) Rich experience in mergers and acquisitions; 2) Management model advantages: design-manufacture-installation integration, project manager responsibility and benefit contract system; 3) brand, technology and construction strength. Hangxiao Steel Structure: A pioneer in the development of residential steel structures and international business, the contract value in 2009 was 3.126 billion yuan, of which overseas contracts were 195 million yuan. Light steel and multi-high-rise steel accounted for 43% and 37% of the revenue, respectively. Southeast Grid: One of the most well-known and strongest large-scale comprehensive steel structure production bases in the country, with strong spatial steel structure. Revenue accounted for 46%. The company's current production capacity has reached 400,000 tons, with orders of 3.521 billion in 2009. Guangzheng Steel Structure: A leading steel structure enterprise in Xinjiang, whose profitability and growth are higher than those in the eastern region. Fully enjoy the regional prosperity and limited competition brought about by Xinjiang's large-scale development.

Industry development is currently in the critical period of the Twelfth Five-Year Plan, and policy guidance is expected to drive the industry momentum and downstream demand for the rapid development of steel structure enterprises. Jinggong steel structure: 2010-12 EPS 0.63, 0.82, 1.07 yuan, target price of 16 yuan; focus on the listing of Guangzheng steel structure.
