About WENZHOU ZHENGXIN PIPE FITTINGS CO., LTD

Our products are widely applied in urban residential buildings, public constructions, tourism facilities, water supply & drainage, direct‑drinking water systems, municipal tap‑water networks, gas supply and industrial facilities.
The company has introduced the QS9000 production management system and passed ISO 9001:2000 quality management system certification. Our products are also CE‑certified. Through the joint efforts of all staff, we have achieved an annual production capacity of 1,000,000 stainless steel pipe fittings and 1,000 tons of stainless steel pipes, with an annual output value exceeding RMB 100 million.
