China's Leading Steel Tanks Manufacturer
In the global industrial landscape, the storage of liquids and dry bulk materials is a fundamental requirement, and the choice of a storage vessel can be the single most critical decision for a project's long-term success. While the market is populated with countless manufacturers, true leadership is defined not by scale alone, but by a relentless commitment to innovation, uncompromising quality, and a proven legacy of trust.
For over three decades, Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) has not only met these standards but has actively set them, establishing itself as the undisputed leading steel tanks manufacturer in China and a globally recognized authority in engineered containment solutions. Our journey from a national pioneer to a worldwide leader is a testament to our core philosophy: that a tank is more than just a container—it is a strategic asset built on a foundation of cutting-edge technology, rigorous compliance, and a deep-seated passion for excellence.
A Legacy of Pioneering Innovation
The story of Center Enamel's leadership begins with a vision. Established in 2008, our company was founded with the mission to revolutionize the steel tank industry by addressing the inherent flaws of traditional methods like welded steel and concrete. We recognized early on that while steel offered superior strength, it required a permanent, robust, and corrosion-resistant coating that could withstand the harshest environments. This led to our most significant breakthrough: becoming the first manufacturer in China to independently develop Glass-Fused-to-Steel (GFS) tank technology.
The GFS process is a marvel of material science. It involves firing a steel plate at a high temperature of 820°C-930°C, causing molten glass to react and permanently fuse with the steel surface. This creates a composite material that perfectly combines the strength and flexibility of steel with the unmatched corrosion resistance of glass. This pioneering step transformed the bolted steel tank from a niche product into a durable, versatile, and long-lasting solution for a wide range of applications, from municipal water and wastewater to complex industrial liquids.
Our commitment to innovation didn't stop there. We further refined the process by developing double-sided enameling technology for hot-rolled steel plates, an advanced technique that provides superior protection on both the interior and exterior surfaces of the tank panels. This unique advantage ensures complete, uniform coverage and a longevity that far surpasses alternative single-sided or field-applied coatings. This relentless pursuit of excellence has culminated in the accumulation of nearly 200 enameling patents, cementing our position as a technological trailblazer.
Uncompromising Quality and Global Compliance
For a steel tank to be considered world-class, it must adhere to a set of global standards that guarantee its safety, performance, and structural integrity. At Center Enamel, our reputation as a leader is built on an unwavering commitment to meeting and exceeding these benchmarks. We do not view certifications as mere formalities; we see them as a solemn promise to our clients that our products are built to the highest possible standards.
Our manufacturing and quality control systems are certified to ISO 9001, a global benchmark for quality management. This ensures that every step of our process, from material sourcing to final packaging, is meticulously controlled. Furthermore, we are certified to ISO 45001, demonstrating our dedication to occupational health and safety, which is a testament to our responsible and ethical business practices.
Our products themselves hold a comprehensive suite of certifications from the most demanding international organizations:
For Potable Water & Public Health: Our GFS tanks are certified to NSF/ANSI 61 and WRAS (Water Regulations Advisory Scheme), which guarantee that the materials will not leach contaminants and are safe for storing drinking water. This is an essential requirement for municipalities and a non-negotiable standard for public health. We are also compliant with LFGB for food contact applications.
For Structural Integrity & Engineering Excellence: Our tanks are engineered to comply with AWWA D103-09, the American Water Works Association standard for factory-coated bolted steel tanks. Our structural steel is certified to CE/EN1090, a standard for load-bearing structures in Europe, and our enamel-coated tanks meet the rigorous requirements of ISO 28765. This extensive list of engineering certifications provides clients with the assurance that our tanks are structurally sound and reliable in any environment.
For Safety & Performance: We are compliant with FM Global and NFPA standards, critical for fire protection systems, and OSHA for safety during installation and operation.
This extensive list of certifications is a powerful differentiator. It proves that our tanks are not just designed to perform; they are certified by independent, global authorities to be safe, reliable, and compliant.
Engineered for the World's Toughest Applications
Our position as a leading steel tank manufacturer is reinforced by the sheer breadth and quality of our product portfolio. We understand that one size does not fit all, and our two primary technologies—Glass-Fused-to-Steel and Fusion Bonded Epoxy—are engineered to excel in specific, demanding environments.
Glass-Fused-to-Steel (GFS) Tanks
GFS tanks are our premium solution, designed for the most aggressive and challenging applications. The glassy, non-porous surface is impervious to a wide range of corrosive agents, from highly acidic wastewater to the organic acids found in biogas reactors. The material's exceptional hardness (6.0 on the Mohs scale) provides unmatched resistance to abrasion from liquids containing suspended solids.
This superior durability translates to an impressive design life of over 30 years, with minimal maintenance requirements. For applications like municipal wastewater treatment, industrial process water, and anaerobic digestion, a GFS tank is a long-term strategic investment that guarantees a low total cost of ownership.
Fusion Bonded Epoxy (FBE) Tanks
For projects where extreme corrosion is not the primary concern, our Fusion Bonded Epoxy (FBE) tanks offer a high-value, durable alternative. The FBE coating is a thermoset polymer powder that is electrostatically applied and then fused to the steel in a controlled factory environment. This process creates a uniform, robust barrier that is far superior to any field-applied coating. Our FBE tanks provide excellent corrosion protection, making them a reliable and cost-effective solution for fire protection, agricultural water storage, and industrial water systems.
Unmatched Scale and Capability
Our ability to handle projects of any scale is another hallmark of our leadership. Our new production base, spanning over 150,000m², is one of the largest and most advanced in the industry. This scale allows us to fabricate projects of monumental proportions, a capability proven by our record-breaking achievements, including the construction of the largest GFS tank in Asia, with a single volume of 32,000m³, and the highest GFS tank, reaching 34.8m. This capacity gives our clients the confidence that we can deliver on even the most ambitious projects.
A Global Footprint of Trust
The ultimate proof of our leadership is our global footprint. Our commitment to quality and compliance has opened doors to the most demanding markets in the world. Our tanks have been exported to more than 100 countries, a testament to the fact that our technology is not just "good for China," but is trusted and accepted worldwide.
Our successful projects span continents, from a drinking water project in the USA to a biogas plant in Malaysia and an irrigation water storage project in Australia. This rich international experience has given us a deep understanding of diverse regulatory environments, logistical challenges, and client-specific needs. We don't just sell a product; we provide a partnership, offering full EPC (Engineering, Procurement, Construction) technical support, from initial consultation and engineering design to on-site installation guidance.
In an industry where reliability is paramount, choosing the right manufacturer is a critical decision. Center Enamel's legacy of pioneering innovation, unwavering commitment to global compliance, and proven track record of delivering superior solutions worldwide make us the clear choice. We are not just a manufacturer; we are the foundation of excellence for your next project.
