Center Enamel Enhances Seychelles Water Infrastructure with GFS Technology
In March 2025, Center Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd.) successfully commissioned a critical drinking water storage project in the Seychelles. This installation provides a scalable, durable, and highly sanitary storage solution designed to withstand the unique challenges of a tropical, coastal environment.
As a global leader in bolted tank manufacturing, Center Enamel utilized its signature Glass-Fused-to-Steel (GFS) technology to ensure the region benefits from long-term, reliable potable water access.

Why GFS Technology for Tropical & Coastal Climates?
The Seychelles archipelago presents significant challenges for water storage, including high humidity, salt-spray air, and intense UV exposure. Standard carbon steel or concrete tanks often succumb to rapid corrosion or bacterial growth in these conditions. Center Enamel’s GFS technology offers specific advantages that mitigate these environmental risks:
1. Superior Corrosion Resistance
The GFS manufacturing process involves fusing glass and steel at 820°C–930°C. This creates a chemically inert, non-porous coating that acts as an impermeable shield. Unlike traditional paint coatings that peel or crack in tropical heat, the glass-fused surface remains stable for decades.
2. Global Safety Compliance (NSF/ANSI 61)
Water purity is non-negotiable. Center Enamel’s GFS tanks are certified to NSF/ANSI 61 standards, which govern the health effects of drinking water system components. This certification ensures that no harmful chemicals leach into the water, even when stored for extended periods in high-heat environments.
3. Hygienic Design
The glass-fused interior is exceptionally smooth, which inhibits the growth of biofilm and bacteria. In a tropical climate, maintaining water hygiene is critical; the GFS surface prevents the contamination issues commonly found in more porous storage materials.
4. GFS Roof Integration
The project included a GFS roof, which is essential for protection against:
● Contamination: Keeps debris, insects, and wildlife out of the water supply.
● UV Exposure: Blocks sunlight, preventing algae growth within the tank.
● Environmental Factors: Protects against heavy rainfall and wind-borne contaminants.
Efficiency and Installation Lifecycle
Beyond the material science, the bolted tank design offers a practical advantage for island infrastructure where heavy construction machinery and skilled welding teams may be difficult to mobilize.
● Prefabricated Modular Panels: The tank components are manufactured in the factory, allowing for quality control that is impossible to achieve on-site.
● Accelerated Assembly: The panels are shipped and bolted together at the project site, significantly reducing the project timeline compared to poured-in-place concrete.
● Lower Total Cost of Ownership: With a service life exceeding 30 years and minimal maintenance requirements (no recurring painting or surface repairs), GFS tanks provide the best long-term return on investment for municipal and industrial water projects.
Frequently Asked Questions (FAQ)
Q: Why was Glass-Fused-to-Steel chosen instead of concrete for the Seychelles project?
A: In coastal environments, salt air can penetrate the microscopic pores of concrete, leading to rebar corrosion and structural degradation. GFS technology offers a non-porous, corrosion-proof surface that is immune to salt spray and significantly faster to install than traditional concrete.
Q: Are Center Enamel tanks safe for long-term drinking water storage?
A: Yes. These tanks comply with NSF/ANSI 61 and other international potable water standards. The interior surface is smooth and inert, preventing bacterial colonization and ensuring that the water quality remains high from intake to tap.
Q: How does the GFS tank perform in tropical weather?
A: The GFS coating is thermally stable and highly resistant to UV rays, meaning it does not degrade or become brittle under intense sun or high humidity. It is specifically engineered to maintain structural and aesthetic integrity in harsh climate conditions.
Q: Can these tanks be relocated or expanded?
A: Because they are bolted modular systems, the tanks can be disassembled and moved if necessary. Additionally, the capacity can often be increased by adding more rings to the existing structure, providing a scalable solution for growing communities.
