Especially in recent decades, the wire industry in China sustained rapid development, with an annual net increase of more than 200 million tons of high speed growth, the yield from 1987 to 693 million tons, increased to 2608 million tons in 1999. An increase of 2.8 times; high speed wire rod production over the same period from 32 million tons increased to 1218 tons, up 37 times; wire self-sufficiency rate reached 99% above; in variety and quality also greatly improved, the current can produce according to the advanced technical indicators. The variety and quality of most lines can meet the requirements of the use of wire products enterprises. All of which shows that China has become the worlds largest producer of wire rod for the worlds attention. But it should also be noted that although China is the worlds leading wire rod production, but also can not be said to be a strong wire production; at present, there are still some types of wire rod still rely on imports to maintain production. Such as steel cord, high stress spring steel, stainless steel, cold heading steel wire. In the physical quality of the important use of wire, still with the worlds advanced industrial countries still have a large gap.
