Leading the Way in Global Water Infrastructure: Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel)

In the rapidly evolving industrial landscape of 2026, the preservation and management of water resources have become the primary focus of sustainable development worldwide. As urban centers expand and industrial processes become more complex, the need for safe, durable, and rapidly deployable storage systems is paramount. Shijiazhuang Zhengzhong Technology Co., Ltd., operating under the globally renowned brand Center Enamel, stands at the apex of this industry as the premier China Glass-Fused-to-Steel (GFS) water storage tank manufacturer.

With a manufacturing legacy rooted in nearly four decades of innovation and a sprawling production base exceeding 150,000 m², Center Enamel has revolutionized the containment sector. By fusing the structural strength of high-performance steel with the chemical inertness of glass, we provide storage solutions that safeguard the world’s most precious resource in over 100 countries.

1. The Science of the Fusion: Understanding Glass-Fused-to-Steel (GFS)

The "heart" of our leadership lies in the mastery of GFS technology—a process that creates a material far superior to traditional concrete or painted steel. Glass-Fused-to-Steel tanks, also known as glass-lined bolted steel tanks, are created through a high-temperature firing process.

The Fusion Process

At Center Enamel, we utilize specialized, titanium-rich steel (TRS) plates. These plates are coated with a proprietary glass frit and fired in automated tunnel furnaces at temperatures ranging from 820°C to 930°C. At these temperatures, the glass and steel undergo an interfacial fusion reaction, forming a permanent, molecular inorganic bond.

Technical Performance Characteristics

2. Global Quality Standards and Certifications

In the water storage industry of 2026, trust is built on compliance. Center Enamel is the first manufacturer in China to produce GFS tanks that meet and exceed the world's most stringent engineering mandates.

AWWA D103-09: The American standard for factory-coated bolted steel water tanks.

NSF/ANSI 61: Global certification for drinking water safety and public health.

ISO 28765: The international standard for vitreous and porcelain enamels.

WRAS & LFGB: British and German certifications for contact with food and water.

FM Global: Insurer-approved standards for fire protection water storage.

Every single plate that leaves our facility undergoes a rigorous 1500V Holiday Test, ensuring that our global partners receive a product with zero coating discontinuities.

3. Advantages of the Bolted Modular Design

Center Enamel’s tanks are engineered for the modern construction environment, where efficiency and site safety are as important as the product itself.

Rapid Construction and Low Cost

Unlike welded tanks, our GFS tanks are delivered as a complete, ready-to-assemble kit.

Top-Down Installation: Using a synchronized hydraulic jacking system, the tank is built at ground level and lifted ring-by-ring. This eliminates the need for massive cranes and significantly reduces the risks associated with "working at heights."

Logistics: A 20,000 m³ tank can be flat-packed into standard sea containers, reducing international freight costs by up to 70%.

Expandability and Flexibility

The bolted nature of our tanks means they are inherently future-proof. If a facility needs to expand its capacity in 2030, additional rings can be bolted to the existing structure. Furthermore, the tanks can be dismantled and relocated if necessary, protecting your long-term capital investment.

4. Diversified Applications Across the Water Sector

While we are the leading GFS tank manufacturer, our engineering team provides integrated storage solutions for the entire water cycle.

A. Potable and Drinking Water Storage

Our GFS tanks are inert and non-porous, preventing the growth of bacteria, algae, and biofilms. They are the ideal choice for municipal drinking water reservoirs, ensuring purity from the source to the tap.

B. Industrial Wastewater and Effluent Treatment

Handling harsh industrial fluids—ranging from chemical processing runoff to high-temperature effluents—requires the extreme chemical resistance that only glass-lined steel can provide.

C. Fire Protection Water Systems

Compliant with NFPA 22 and FM Global, our fire water tanks provide a reliable, maintenance-free reservoir for industrial plants, airports, and high-density residential complexes.

D. Anaerobic Digestion and Biogas

The airtight integrity of our bolted tanks makes them the primary reactor for waste-to-energy projects. As the leading China Digester Tank Manufacturer, we help convert municipal sludge and agricultural waste into renewable energy.

5. Strategic 2026 Outlook and ESG Commitment

As Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) looks forward, our commitment to Environmental, Social, and Governance (ESG) principles remains unwavering.

Sustainability: Our tanks are 100% recyclable, and our factory-based manufacturing process significantly reduces on-site construction waste and local environmental disruption.

Innovation: With over 200 enameling patents, our R&D center continues to develop anti-microbial coatings and high-end materials designed for the next generation of industrial storage.
