Recently, as the international iron and steel association predicts, under the influence of the euro zone debt crisis in 2012, the demand of iron and steel will decline 5.6% in 27 countries of European Union compared with the same period in 2011. Jorgen Nasser, executive director of the European steel dealers association (Euro metal) said that low demand still is the key problems faced by the European steel market; therefore it has brought excess capacity of the iron and steel production and low utilization.

However, with the policy of implementation of steel structure and the development of steel construction housing and engineering promoted by our government, the demand of the steel in china is still growing day by day. Nowadays, China has been the largest exporting and consuming country in steel and iron industry all over the world. As is introduced, the market in China has great potential for the development of the steel industry at home and abroad. During these days, many mining giants such as BHP Billiton display optimistic expectations to "China needs", and increase their production in succession. Besides, as the figures shown by China's industrial development research network, we have increased the importing amount since 2011 from many countries, such as: Indonesia, Australia etc.

As is shown in the development trend of steel industry these years, much more communication between countries is in urgent need. So Steel Build 2015 is really an effective way to achieve this goal. It is really a must-attending event about steel construction industry, for more than 25 thousands professionals will join this grand gathering. At that time we will boost the development of the steel industry in the state of prosperity.
