Every year,Changsha Water Group invites the leading piping infrastructure suppliers of China to bid on its budgeted annual pipeline procurement program for the coming year. For this year's bid,ZK International was selected as the major supplier for the projects and ranked number two among all approved suppliers after a comprehensive assessment of product quality,delivery capacity,and engineering support. It is estimated that over $30 million in stainless steel piping infrastructure will be purchased throughout the year for various projects through one or several suppliers at Changsha Water Group's discretion. Historically,bidders ranked first and second are each allocated approximately 30% of the total stainless steel pipe purchases during the year.

Mr. Jiancong Huang,Chairman of ZK International,commented,"We are pleased to once again be selected as one of only a few suppliers to partner with Changsha Water Group in its effort to upgrade the existing water infrastructure of the city.
