"Here, you can feel the world is connected. The industrial chain, chain up every corner, every group, we stand here and deliver products, hopes, and multiple scenes of life to the world ......" Liu Huiwu, director of Jinghai District Development and Reform Commission, introduced it with gusto.

In a workshop in Jinghai, there is a seesaw with the earth model at one end. People can lift it high at the other end. The lever used to pry the "earth" is the structural steel pipe produced by the company. This company is Jinghai YuanTai DeRun Group, the world's first 5 million ton square rectangular steel pipe manufacturing enterprise. After a difficult transformation, its cost, efficiency, benefits and all aspects have made qualitative leaps. In particular, the improvement of quality has enabled the Group to completely open the overseas market.

"Every year, more than 10000 tons of every kind of steel pipes are exported, and the market is spread across the EU, the Americas, Africa, Southeast Asia and other countries and regions. Each bundle of rectangular pipes exported is labeled with" Yuantai "." Gao Shucheng, the general manager of the group, said that the product quality is the largest asset of the group. Recently, Tianjin Yuantai Derun Steel Pipe Group once again became the champion of China's rectangular tube single product. In addition, Jinghai is still exploring to leave more dividends in the industrial chain at home. On the basis of optimizing the rectangular tube industry, we will focus on the development of high value-added industries such as prefabricated and photovoltaic support. Gao Shucheng believes that with the deepening of reform, "high-end" will become the label of Chinese products.
