ZK International to Benefit from New Green Building Standard That Went into

Effect on August 1, 2019

WENZHOU, China, Aug. 20, 2019 -- ZK International Group Co., Ltd. (ZKIN) ("ZK International" or the "Company"), a designer, engineer, manufacturer, and supplier of patented high-performance stainless steel and carbon steel pipe products primarily used for water and gas supplies, today announced that the Chinese government started implementing a new Assessment Standard for Green Buildings (‘the New Standard”) this month, which the Company believes provides a favorable catalyst for the stainless steel pipe industry for years to come and could potentially benefit companies such as ZK International.

The New Standard, coded with National Standard No.: GB/T50378-2019, was jointed promulgated by the Ministry of Housing and Urban-Rural Development and the State Administration for Market Regulation on March 13, 2019 (Notice No. 61) and went into effect on August 1, 2019. As part of the New Standard, it requires the mandatory use of stainless steel or copper pipes over more traditional PPR, synthetic plastic or galvanized pipes for water supply.

Mr. Jiancong Huang, Chairman and Chief Executive Officer of ZK International, commented, "the Chinese government has been encouraging broader application of stainless steel water supply pipes in recent years on the back of increasing evidences of and concerns over secondary pollution in the water pipe network using PPR, synthetic plastic, or galvanized pipes. The New Standard is a testament to the government’s commitment to the water infrastructure upgrade initiatives. According to the National Bureau of Statistics of the PRC, the water supply pipe market reached RMB610.3 billion in 2018, of which stainless steel pipes only accounted for approximately 30% of total. We expect the New Standard to drive accelerated growth of the stainless steel pipe market that would benefit companies like us.”
