Center Enamel: China’s Leading Water Storage Tanks Manufacturer Shaping the Future of Global Water Infrastructure
Water sustains civilizations, fuels industrial growth, and anchors agricultural productivity. Yet, the world continues to face growing challenges—climate variability, population expansion, water scarcity, and the increasing demand for reliable, sustainable storage infrastructure. Among the leading innovators tackling these challenges stands Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), recognized as China’s premier manufacturer of high-performance bolted steel water storage tanks.
Since its founding in 2008, Center Enamel has evolved from a regional enterprise into a global leader in water storage technology, serving customers across more than 100 countries. The company’s success is built upon advanced Glass-Fused-to-Steel (GFS) technology, world-class engineering expertise, and a solid commitment to sustainability and water management solutions that meet the demands of the 21st century.
From Local Innovator to Global Leader
Founded in Shijiazhuang, China, in 2008, Center Enamel made history as the first Chinese company to independently develop double-sided enameling technology for hot-rolled steel plates. This breakthrough marked a major milestone for the Chinese manufacturing industry, setting the foundation for localized production of Glass-Fused-to-Steel tanks, which had previously relied on imports.
Through continuous research and technological advancement, Center Enamel earned its reputation as Global leading bolted tank manufacturer, building tanks that are exported to more than 100 countries across North America, South America, Europe, Africa, the Middle East, and Southeast Asia.
Over nearly two decades, Center Enamel has consistently invested in talent, manufacturing infrastructure, and research, nurturing an R&D team with nearly 200 enameling technology patents. With its integrated capabilities—from product design and testing to engineering and service—the company represents not only China’s industrial strength but also the emerging face of sustainable global manufacturing.
Advanced Coating Technology: The Core of Durability
The differentiating strength of Center Enamel tanks lies in its proprietary coating technologies, which ensure long-lasting performance even under extreme environmental conditions.
Glass-Fused-to-Steel (GFS): The Golden Standard
Glass-Fused-to-Steel, also known as enamel-coated steel, is a fusion of two enduring materials—steel and glass. The process involves firing molten glass onto steel at high temperatures between 820°C and 930°C, permanently bonding the two materials to form an inert, anti-corrosive, and glossy surface.
This robust coating technology brings several unmatched advantages:
· Superior Corrosion Resistance: Exceptional durability against pH ranges from 1 to 14, resistant to acids, alkalis, and chlorine.
· Smooth, Non-Porous Finish: Prevents bacterial growth and ensures hygienic conditions ideal for potable water.
· Extended Service Life: Designed lifespan exceeding 30 years, outperforming welded steel and concrete counterparts.
· Impenetrable Surface: Resistant to UV rays, chemical reactions, and temperature variations.
· Environmental Compliance: Non-toxic, eco-friendly production meeting international sustainability standards.
GFS tanks are suitable for potable water, wastewater, agricultural irrigation storage, fire protection, desalination projects, and industrial systems.
Fusion Bonded Epoxy (FBE): Precision and Protection
For specialized applications, Center Enamel also manufactures Fusion Bonded Epoxy (FBE) coated tanks. In this process, epoxy powder is electrostatically applied to steel and cured to create a seamless protective layer.
FBE coatings excel in environments requiring efficient corrosion protection, such as chemical industries, desalination plants, and municipal wastewater systems.
Modular Engineering: Innovation in Structural Design
Center Enamel’s bolted steel tanks are designed using modular construction principles that offer superior flexibility, speed, and cost-effectiveness compared to conventional concrete or welded tanks.
Key Features of Modular Design:
· Prefabricated enamel-coated steel panels assembled onsite using specialized bolts and gaskets.
· Flexible capacities ranging from 20 m³ to over 50,000 m³, adaptable for projects of all sizes.
· Scalable configurations for future expansion or relocation.
· Fast onsite assembly (installations completed in 30–50% less time than concrete).
· Leak-proof seals ensuring 100% impermeability.
By manufacturing panels in a controlled environment and assembling them onsite, Center Enamel minimizes environmental disruption, shortens delivery cycles, and ensures precision quality regardless of project location.
Globally Recognized Quality and International Certifications
Center Enamel’s commitment to excellence is reinforced by comprehensive certifications from leading global authorities. Each tank manufactured undergoes rigorous quality control from raw material selection to final assembly.
