In recent decades, the three countries of the former Soviet Union, the United States, Japan has been the steel output ranked the top three countries, the output of steel turns ranked first in the international. Therefore, these countries, the construction of a steel structure construction enterprise vigorous development. While in the same period, China's development in this area is relatively slow, the level is relatively backward. In recent years, with the implementation of China's reform and opening up policy, China's economic construction has made rapid progress. During this period, China's steel production has become the first international.
In 1996, China's steel production for the first time to break the million tons; in 1998, China's steel output has reached 11434 million tons and annual yield increase of 300 million tons of steel production for the development of China's construction of steel structure building construction has created great opportunities. But now, our country and the developed countries compared in many ways still exist significant distances, so in order to promote our country to build the steel made the further development and use, we need to understand the foreign building steel using sketchy.
The total amount of steel in our country is about 25% to 20% of the total steel production, while the industrial developed countries account for more than 30%. Such as the United States and Japan, the project have exceeded 50%. In our country, steel construction is mainly used for building made of steel, steel bars for concrete reinforcement, steel wire, steel wire, doors and windows, and the steel steel accounted for only 10% the left and right sides, in China 100 million tons of steel production, true for steel manufacture is 200 ~ 300 million tons.
According to the 1998 mid American metal construction industry spread some of the data and the metal building is the basic situation of the development of the industry and the market: in the 20th century 50, 60, 70, in the 1980s and 1990s, in millions of dollars in annual sales / with tons of annual processing capacity of parting 150/30 / 65, 1200/110, 1500/125 and 2200/190, such as during the 1950s, as an example the corresponding increase multiple parting reached 1, 2 / 2. 2, 8. 7, 10 / 5. 7 and 15/6.3 times. Can be seen from the United States, the construction of the metal in the year of the increase in sales of very fast, now has more than 2 billion 500 million U.S. dollars, the annual processing capacity has reached more than 2 million tons.
