WENZHOU,China,Oct. 9,2018 -- ZK International Group Co.,Ltd. (Nasdaq: ZKIN) ("ZKIN","ZK International" or the "Company"),a designer,engineer,manufacturer,and supplier of patented high-performance stainless steel and carbon steel pipe products that require sophisticated water or gas pipeline systems,today announced that the Company has been chosen by Zhuhai Water Environment Holding Group Co.,Ltd. ("Zhuhai Water"),as a leading supplier of stainless steel piping for updating the water supply infrastructure in Zhuhai,China.

Zhuhai is a city on the southern coast of Guangdong province in China,located in the Pearl River Delta that borders Hong Kong and Macau. In November 2017,the municipal government issued regulation to immediately begin updating the existing water supply infrastructure by increasing the use of stainless steel piping and decreasing the use of plastic and galvanized piping in the water supply infrastructure due to the potential contamination they may cause to the water. To conform to the new regulation,Zhuhai Water organized a call for tenders to invite leading stainless steel pipe manufacturers in China to bid for stainless steel pipe procurement program in 2019.

The China Water Network and China Water Supply and Drainage Committee have recognized Zhuhai Water as China's most socially responsible water service enterprise and one of China's top 40 most influential water groups. Zhuhai Water evaluated each bid by various criteria,such as production flow,manufacturing capacity,delivery period,and financial liquidity. Among all the companies that were accepted as suppliers,ZK International ranked number one. Due to the new regulations in place regarding piping material,Zhuhai Water is going to use stainless steel pipe for all of its future water pipe construction projects and pipe replacement projects. By ZK International's estimate,the total demand of stainless steel pipe by Zhuhai Water for the next year should amount to approximately $2 million to $3 million.

Mr. Jiancong Huang,Chairman of ZK International,commented,"We are pleased to be selected first amongst several of our competitors during this bidding process,as well as,begin a new working relationship with Zhuhai Water. We look forward to cultivating our relationship with their team and being part of the new government regulations in the Guangdong province."
