Steel structure has high strength, light weight, great impact resistance features that is able to be used for different climates and green projects. It is cheap and can be recycled. The most important is that steel can reduce pollution of the environment. Several years ago, there is a great demand of steel in infrastructure construction, real estate, household appliance manufacturing industry, shipping industry and other industry. So many steel coil manufacturers add relevant production lines of steel products. But with slowing economic growth later, the fast development of the production lines become production surplus. 

What should we do to overcome production surplus these years? Steel coil manufacturers should build long plan and promote steel industry upgrading. Pay more attention to market and make full use of econoic means to solve surplus problem. Analyse the market condition to find a new way that is suitable for our own development. Cooperating with international partner will not be a bad method and can also take good quality steel product out. We should protect the environment and save energy at the same time. Either steel coil manufacturers or traders, they have a strong willing to reduce stock but the demand decreased which led to low steel price. 

On the other hand, China steel technology can not meet its scale. It lacks innovative strength like steel industrial patent. So that we have much to do to improve our own innovative ability to become one of leading steel coil manufacturers.
