In recent decades, Russia, the United States, Japan, three countries have been the world's steel output ranked the top three countries, which steel output ranks first in the world turns. Therefore, these countries steel construction the building boom. 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 and promote China's economic construction has made rapid progress. During this period, China's steel production became the first in the world. 1996 million tons of steel production mark for the first time; 1998 China's steel output reached 114.34 million t, and each year 300 million increase t. The growth of steel production in China for the development of steel construction buildings and create an excellent opportunity. But now, China and the developed countries there are still many significant gaps, therefore, in order to promote the further development of China's steel structure and application, we need to understand the application of foreign construction steel profiles. Total amount of construction steel in China's steel production accounting for about 20% to 25%, while industrialized countries account for more than 30%. Such as the United States and Japan, the indicators have been more than 50%. In China, the steel is mainly used in building construction steel, reinforced concrete with steel bars, steel wire, steel wire, doors and windows, of which only 10% of the steel structure of steel in China one million tons of steel production in , also on the real steel for the 200 to 300 tons.  According to the U.S. in mid-1998 the distribution of the metal construction industry, some of the data, the U.S. metal building industry and the market's basic situation: in the 20th century, 50,60,70,80 and 90 years, millions of dollars in annual sales / in thousands of tons of annual processing capacity were 150/30, 300/65, 1200/110, 1500/125 and 2200/190, as an example of 50 years, respectively, the corresponding increase in multiples of 1,2 / 2  2, 8 / 3  7,10 / 5  7 and 15/6.3 times. Can be seen, the United States with annual sales growing rapidly with a metal building, estimated that more than 25 billion U.S. dollars, an annual processing capacity has reached 200 million tons. Because the building has many years experience in translation, Guangzhou, China Translation Translation Translation of the country for the construction industry has now gained appropriate professional terminology database to ensure translation accuracy and professionalism. The level of high-quality translation is based, we have been in Guangzhou, Beijing, Guangzhou and Shenzhen, where many construction companies and construction units to provide a professional translation service. We always take the quality of translation as the basis for the development of translation companies, and also high-quality translation service to win customers trust.
