INTRODUCTION
Tangshan Huijin Trade Co.Ltd was initially founded in March, 2006 with a registered
capital amounting to 23,000,000. Its predecessor—Yutian Yuanfang logistics Co.Ltd was
established on May 4, 1998. To enlarge the business scope of Huijin, Tianjin Yutian
Yuanfang Steel Trade Co.Ltd and Tangshan Degao Trade Co.Ltd were established
respectively. Tangshan Huijin Trade Co.Ltd deals mainly in Cold-rolling steel products,
cold-rolled, hot-rolled steel sheets, and zinc-coated steel sheets which are produced by
Tangshan Iron and Steel Co. Ltd , Baosheng Iron and Steel Co. Ltd, Tianjin tiantie Iron
and Steel Co. Ltd, Tianjin Xinyu Co. Ltd and other steell companies in the North
China.Huijin has adopted efficient management system, and has made great progress in
its business line. As the first-grade agent of Tangshan Iron and Steel Co. Ltd and Tianjin
Tiantie Co.Ltd, Huijin has been awarded “consumer trusted company” by Local
Commercial and Industry Bureaus for 5 years ( from 2003 to 2007 ), at the same time,
Huijin has been rated as AA level and above credit enterprises. In 2007, the total sales
amount of Huijin reached 180,000 tons, and the turnover exceeded 1,000,000,000 RMB.
The total sales amount of 2008 is expected to reach 250,000 tons, and the turnover can
exceed 1,500,000,000 RMB.
Since the foundation of Huijin, we take “honesty, credit, pragmatic, progress” as our
motto. With our safe purchase channels, improved distribution networks, dedicated staff,
and honest business operation, Huijin receives universal praise under fierce competition
in the market. With the continuous update and development of business mode and
philosophy in trade practice, we always hold on the policy—Advance With the Times.
Under the circumstance of huge market demands, our company will continue to sell steel
products, and our sales will be based on Tianjin and other domestic markets. To enhance
the overall strength of Huijin, we will actively explore new ways in circulation and trade
circle, and find the benefits of new growth points which will lay a solid foundation for our
further development.
