In the rapidly evolving landscape of global water security and industrial liquid management, the demand for resilient, scalable, and high-performance storage infrastructure has never been greater. As nations face the dual challenges of climate-induced water scarcity and the need for rapid industrial expansion, traditional construction methods—such as reinforced concrete and field-welded steel—are often found lacking in speed, logistical flexibility, and long-term durability.
Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) stands at the forefront of this shift, serving as a premier global manufacturer of Glass-Fused-to-Steel (GFS), Fusion Bonded Epoxy (FBE), and Stainless Steel Bolted Tanks. With a project footprint spanning over 100 countries and adherence to the most stringent international standards (AWWA D103-09, NSF/ANSI 61, ISO 28765), Center Enamel delivers the "Gold Standard" in liquid containment.
At the heart of Center Enamel’s global success is Glass-Fused-to-Steel technology. This "best-of-both-worlds" material combines the structural strength and flexibility of high-grade carbon steel with the permanent corrosion resistance of glass.
Unlike traditional paints or coatings that are applied to the surface, the GFS process involves fusing a specialized silica-based enamel to the steel substrate at temperatures ranging from 820°C to 930°C. This creates a physical, molecular bond that is harder than the steel itself.
● Inert Surface: The glass lining is chemically inert, making it ideal for potable water storage. It prevents the "iron pickup" or mineral leaching common in uncoated steel or aging concrete.
● Impact & Abrasion Resistance: The high-fired enamel surface resists scratching and impact, maintaining its integrity during transport and assembly.
● Low Maintenance (OPEX): GFS tanks require zero repainting over their 30-year design life. This significantly reduces the Total Cost of Ownership ($TCO$) compared to welded tanks that require sandblasting and recoating every 5–10 years.
A definitive example of Center Enamel’s capability is the 2022 Kenya Drilling Water Project. This large-scale infrastructure initiative was designed to provide a secure drinking water supply in a remote, arid region characterized by logistical hurdles and extreme UV exposure.

Configuration | 2 Units x 4,280 m3 |
Dimensions | 27.52 m x 7.2 m (H) |
Tank Type | GFS Bolted Steel |
Roofing | Aluminum Alloy Trough Deck |
Remote accessibility is a primary pain point for African infrastructure. Traditional concrete reservoirs require a massive influx of sand, gravel, and water, which are often unavailable at drilling sites.
● Modular Freight: Center Enamel’s bolted steel tanks were packed into standard 40ft containers. This allowed for transport from the Port of Mombasa to the inland site via standard truck chassis, reducing freight costs by 40%.
● Rapid Commissioning: Using a synchronized jacking system, the tanks were assembled from the top down without the need for scaffolding. This allowed the project to go live 60% faster than a concrete alternative.
A storage tank is only as reliable as its seal. For the Kenya project and various global oil storage applications, Center Enamel utilizes Aluminum Alloy Trough Deck Roofs.
In high-UV environments like Kenya or Southeast Asia, traditional steel roofs are prone to atmospheric corrosion and UV degradation. Aluminum alloy provides:
1. Algae Prevention: By completely blocking UV penetration, the roof prevents the growth of photosynthetic microorganisms in potable water storage.
2. Corrosion Resistance: Aluminum’s natural passivity makes it maintenance-free, even in high-humidity or coastal areas.
3. Airtight Contamination Control: The precision-engineered deck creates a barrier against dust, insects, and birds, ensuring the fluid meets ISO 4406 Cleanliness Standards.
Beyond drinking water, Center Enamel’s engineering expertise extends to specialized industrial sectors.
Our fire water tanks are designed in strict accordance with NFPA 22. These systems are critical for industrial facilities, featuring:
● Anti-Vortex Technology: Custom suction plates ensure maximum flow rates during emergencies without air entrainment.
● Temperature Management: Integrated heating systems maintain water at 5.6°C (42°F) in cold climates to prevent ice damage.
For the automotive and energy sectors, we manufacture Carbon Steel Lubricating Oil Tanks utilizing high-strength Q235B steel.
● Viscosity Management: Our tanks integrate 304/316 stainless steel heating coils to maintain optimal flow temperatures for heavy gear oils.
● Purity Preservation: Internal epoxy liners prevent "iron pickup," protecting the delicate additive packages (like ZDDP) in modern synthetic lubricants.
Center Enamel’s commitment to quality is verified by a comprehensive portfolio of international certifications. This transparency is why EPC contractors and municipal governments trust our solutions.
● NSF/ANSI 61: Verification for drinking water safety and health effects.
● AWWA D103-09: The benchmark for bolted steel water storage design.
● ISO 28765: The international standard for vitreous and porcelain enamels.
● EN1090: Compliance for the execution of steel structures in the European market.

As the world moves toward "Green Building" and sustainable infrastructure, Center Enamel is leading the way. Our GFS tanks are 100% recyclable and possess a carbon footprint significantly lower than that of concrete, which is carbon-intensive in its production and transport.
In regions facing acute water stress, the ability to deploy modular construction water tanks in under 45 days is a literal lifesaver. Our systems serve as the backbone for regional drought relief, accumulating groundwater during high-yield periods to ensure stable distribution during dry spells.
Choosing a storage solution is not just about the tank; it is about the engineering partnership.
● Customized System Integration: We provide fully integrated components, including level sensors, purification loops, and specialized breathers.
● Expert Supervision: Every international project, from the Philippines to Panama, is supported by our technical team to ensure NDT-verified structural integrity.
● Logistical Mastery: Our proximity to major shipping hubs and mastery of containerized freight ensures that your project remains on budget and on schedule.
Whether it is securing a 8,500m³ potable water supply in Kenya or managing high-value lubricating oils for an industrial plant, Center Enamel provides the most reliable, durable, and cost-effective storage solutions available today. Our fusion of material science and modular engineering ensures that your vital liquid assets are protected for decades to come.
Don't settle for "standard" storage. Secure your infrastructure with the global leader in bolted tank technology.
