Shijiazhuang Zhengzhong Technology Co., Ltd.: A Legacy of Innovation and Global Growth
For over two decades, Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) has pioneered the development of enamel-lined assembled tank technology. From our early breakthrough as the first professional manufacturer of this technology in Asia, to our current status as a global leader managing multi-thousand-cubic-meter projects, our growth path is a testament to unwavering engineering standards and a commitment to international expansion.
1. Foundation and Breakthroughs (Early Years – 2009)
Our trajectory began with a focus on technical superiority in the domestic Chinese market. We fundamentally changed the industry landscape by successfully developing double-sided enamel-lined hot-rolled steel plates.
● Pioneering Status: Became the first professional enamel-lined assembled tank manufacturer in Asia.
● Foundational Projects: Completed the initial Beijing Shunyi Wastewater Treatment Project, validating our technology's viability in large-scale municipal infrastructure.
● The Olympic Milestone (2008): Secured our position as the designated supplier for the Beijing Olympics wastewater treatment project, a pivotal trust signal that solidified our reputation.
● Global Vision (2009): Partnered with a major central state-owned enterprise, marking our first successful expansion into international markets.
2. Global Expansion and International Standards (2010 – 2018)
As our project portfolio expanded across Africa and Southeast Asia, we focused on aligning our manufacturing processes with the highest global benchmarks.
● International Certification (2015): Achieved the prestigious NSF61 international certification, making us the first enamel tank manufacturer in Asia to do so. In the same year, we established a strategic partnership with a premier U.S. storage tank company.
● Breaking Height Records (2018): Successfully completed the Indonesia Fire Water Tank Project, establishing a new record for the tallest enamel-lined assembled tank in Asia at 34.8 meters.
3. Innovation and Peak Performance (2019 – 2021)
During this period, we transitioned from a component supplier to an end-to-end industrial solutions provider, characterized by rapid technological advancement and official national recognition.
● Technological Pinnacle (2019): Perfected a two-stage enameling and firing process for hot-rolled steel plates, representing the highest standard of enamel technology in Asia.
● Manufacturing Excellence (2020): Completed the Swaziland Industrial Wastewater Storage Tank Project, setting the record for the largest single-tank volume for an enamel-lined assembled tank in Asia (21,094 m³). This achievement earned us the Provincial Manufacturing Single Champion Award.
● National Recognition (2021): Passed the National Specialized, Refined, and Innovative "Little Giant" Certification, confirming our status as a high-growth, high-tech enterprise. In the same year, we launched our first self-developed Aluminum Dome Cover project.
4. Scaling New Heights (2022 – Present)
Building on our foundation of innovation, we have scaled our production capacity and global footprint to meet the increasing demand for sustainable infrastructure.
● Strategic Growth (2022–2023): Held the groundbreaking ceremony for our new headquarters production base, which officially commenced production in 2023. This year also marked our achievement of the EU CE Certification, further solidifying our presence in the European market.
● The 2024 Milestone: Launched the Italy Project, which currently holds the record for the largest single tank volume of enameled assembled tanks worldwide at 30,549 m³.
