The rapid growth of the domestic steel production and laid the foundation for the development of steel industry

The rapid growth of the domestic steel production steel construction industry development foundation laid

The rapid growth of China's steel output has laid a good foundation for the development of steel construction industry:

Steel production

2005 Chinese steel production reached 349.4 million tons, accounting for 31.6 percent of global output, the sum of the United States, Russia, Japan and South Korea have been exceeded.

Steel construction accounts for about 5% of steel production, construction steel construction industry is one of the largest steel industry, steel production by 3% for the construction of steel structures, ie more than 1000 tons.

Large landmark has become fashionable to use steel structure, steel structure has been widely used throughout the industry showing a thriving scene.

Development of steel industry in Foshan

Early 1990s: Steel house built 300 million square meters / year, processing more than 100 tons of steel structure, steel structure production equipment more than 400 companies.

2005: Steel house built more than 28 million square meters / year, processing more than 1,000 tons of structural steel, there are market access conditions for the production of steel construction company thousands of devices. Supporting the construction industry and steel-related companies and is not registered there are tens of thousands of small companies. Where: annual output of 20,000 tons, about 50; part of the company's annual production of 100,000 tons or more.
