Sobre nosotros WENZHOU ZHENGXIN PIPE FITTINGS CO., LTD

Wenzhou Zhengxin Pipe Industry Co., Ltd. was founded in August 2013. We focus on the R&D, production and sales of new‑type water supply pipeline systems.
Our self‑developed products, including European‑standard single press‑fit fittings, Chinese‑national‑standard double press‑fit Series 1 and Series 2, socket‑weld and grooved quick‑assembly metal pipelines, are well‑received and highly praised by customers at home and abroad.
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. While our double press‑fit Series 1 & 2, socket‑weld and grooved fittings sell well in the domestic market, we have successfully entered European and American markets with a stable customer base.
We uphold the service philosophy: “Full‑quality service, century‑long maintenance‑free performance; Integrity First, Quality First, Customer First, Service First”. We pursue excellence and continuous innovation, refining every product detail to realize a service life matching that of buildings with zero maintenance. Guided by the business tenet of integrity and win‑win cooperation, we build a sound corporate environment. We take innovative management modes, mature technologies, thoughtful services and superior quality as our cornerstone. We always put customers first, serve clients whole‑heartedly and win recognition with reliable product quality. We strive to develop best‑in‑class pipeline management solutions for the future.
