In the recent steel diving market, the rebar, wire rod as the representative of the long wood, showing better resistance than the plate. Insiders said that the optimization of steel product structure can not blindly pursue high-end technology content, should be market-oriented, to prevent the serious oversupply of single steel varieties, impact on the market and impact. China Iron and Steel Industry Association released data show that the end of 10, the domestic steel composite price index was 108.59 points, down 35.35 points, a decline of 24.56%, October since 2001, the biggest monthly decline in the price index. Sub species, the end of 10 long timber price index was 110.47 points, down 33.21 points, a decline of 23.11%; plate price index of 106.74 points, down 37.24 points, a decrease of 25.86%. Specifically, the plate decline is particularly fierce, individual varieties fell nearly 50%, while the long material rate of decline is relatively small, the cumulative decline of 38%, Shanghai 20mm two screw prices in late September and 4.75mm carbon hot rolled prices, late October is more anti HRC price, the price difference between the two is the highest up to 400 yuan / ton. The price is lower than the hot rolled steel, make domestic projects each with tens of millions of tons of steel plate mainly in an awkward position, also let the major steel mills have to re consider the optimization of product structure thinking. A Beijing area steel trader to Hua Caixun said, at present domestic steel facing enormous pressure on the stock, to promote the sales staff all out of Baosteel, which is rare in the past. And when they sell, the most concerned question is what kind of product is available on the market. In this regard, the executive vice president of Chinese iron and Steel Industry Association, Luo Bingsheng warned that there are some differences among the consumption structure of present product structure China stainless steel tube production market with apparent consumption, should attract attention in domestic and international market demand weakened, the consumption structure of the steel will also change, to adapt to the production of steel structure products for this change, to prevent serious oversupply of steel products for single impact and impact on the market. Rebar and wire rod as the representative of the long material due to the cost of production is relatively low, the process is relatively simple and has been regarded as low value-added steel products, iron and steel industry in Chinese in recent years, the rapid expansion of production capacity, to grow stronger in the process, the major domestic steel prices have increased R & D investment, to strip in the production of high value-added steel, equal timber yield decreased year by year. It is reported, including Bayuquan Anshan, Shougang Beijing Tangshan Iron and steel, Baosteel Zhanjiang, Fangchenggang Liuzhou Iron and steel Wuhan Iron and steel and other large projects, is the basic of hot rolled wide strip steel rolling mill, cold rolling and wide heavy plate rolling mill as the focus, according to incomplete statistics, by the end of 2008, China hot rolled wide steel strip rolling mill production capacity will reach 1.72 tons, is expected to more than 2009 at the end of the year over the same period of 2 tons, steel plate production capacity will reach 58 million 300 thousand tons and 73 million tons respectively. In recent years, as long as the steel plant has new projects, basically the same, with plates, rebar and wire basically become the main production of small and medium-sized steel mills, and new production capacity is very limited. Although the long wood board will face the dual pressures of domestic demand due to the economic slowdown and sluggish external demand, due to the deterioration of the international economic environment and reduce the investment for 4 trillion countries, but the demand for long products provide a guarantee, but not from the new capacity of the pressure, the surface of the supply and demand situation is low growth and low demand. The plate is of high growth and low demand for long products so the overall trend is expected to continue strong in the plate. Guoxin Securities in the latest research report on the contribution of increased infrastructure investment in steel consumption forecast, the amount of investment 4 trillion assumes that the railway and highway investment since 2008 were 300 billion yuan and 610 billion yuan, 45 million yuan in 2009 and 2010 850 billion yuan, 550 billion yuan and 900 billion yuan, then this three years of railway the use of steel and steel highway will reach 5 million 500 thousand tons and 10 million 500 thousand tons in 2009, 8 million 200 thousand tons and 14 million 500 thousand tons, 14 million tons and 15 million 800 thousand tons in 2010. In three years, the contribution rate of steel consumption was 3.56%, 4.73% and 5.96% respectively. From the investment of steel varieties, the main consumption of highway construction steel, wire rod, hot-rolled steel plate, steel and galvanized steel pipe, construction steel production enterprises have a higher proportion of Bayi Iron and steel Minguang, Laiwu Steel; and a large number of needs in the construction of railway rail, Panzhihua steel, Baotou Steel, Anshan Iron and steel will benefit; steel wheel, Maanshan will from the 90% share of the national benefit.
