GFS Fire Water Tanks: Reliable Fire Protection with Superior Engineering and Global Standards
In industrial facilities, commercial complexes, energy plants, and municipal infrastructure, maintaining a reliable fire suppression water supply is essential for safety and resilience. Glass-Fused-to-Steel (GFS) Fire Water Tanks, manufactured by Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), represent the world’s most advanced fire protection water storage technology. Combining steel’s strength and glass enamel’s corrosion resistance, these tanks deliver decades of dependable performance with minimal maintenance requirements.
A GFS Fire Water Tank is a bolted modular tank system built using glass-fused-to-steel panels, connected by high-strength bolts and sealed with industrial gaskets. Each panel is coated with a specialty vitreous enamel layer that fuses with the steel structure at temperatures between 820°C–930°C, forming a permanently bonded composite of steel and glass.[1][2][3][4]
This process creates a durable, corrosion-resistant, and non-porous surface ideal for storing fire suppression water long-term—without the maintenance issues found in concrete or welded tanks. The advanced engineering makes GFS tanks the preferred solution for commercial, municipal, and industrial fire protection systems.
Center Enamel’s GFS tanks are manufactured using a tightly controlled production process that ensures high performance and consistent quality:· Surface Preparation:
Steel plates are shot-blasted to remove oxides, rust, and imperfections, achieving a clean substrate for enameling.
· Application of Glass Frit: A fine layer of glass powder is electrostatically sprayed on both sides of each steel plate.
· Fusion at High Temperature: Panels are fired in a furnace at 820–900°C, permanently fusing the glass and steel into one material.· Quality Testing: Every panel undergoes a 1,500V spark test, adhesion testing at 3,450 N/cm
Through this process, Center Enamel creates tanks that resist corrosion, chemicals, and high temperatures—key requirements for long-term fire water storage.
The GFS fire water tank design uses prefabricated panels, high-tensile bolts, and flexible silicone gaskets. This modular structure simplifies transport and enables quick onsite installation—often in a fraction of the time required for conventional welded or concrete tanks.
· Ease of assembly: No on-site welding or coating needed.
· Reusability: Tanks can be expanded, relocated, or reconfigured easily.
· Efficient logistics: Panels are flat-packed for economical global shipment.
Center Enamel’s tanks are designed to meet or exceed major international standards for fire protection and pressure containment:
· AWWA D103 – Bolted steel tank standard (for potable and industrial water).
· NFPA 22 – Fire water storage tank standard.
· FM Certified – Factory Mutual approval for fire protection use.
· ISO 28765 – Design and manufacture of enameled steel tanks.
· WRAS / NSF/ANSI 61 – Hygiene certification for water storage.
These certifications guarantee that every GFS fire water tank provides reliable performance under emergency conditions.

These materials give GFS tanks exceptional resistance to corrosion, erosion, heat, and UV degradation, making them reliable even after decades of service.
The glass-enamel coating forms an inert barrier that prevents rust and corrosion—even in humid, chemical, or saline environments. Unlike epoxy or painted tanks, GFS surfaces never require recoating and maintain their integrity for over 30 years.
Factory-fabricated panels minimize onsite labor and project timelines. Bolted modular assembly eliminates the need for expensive welding, painting, or curing processes—reducing total cost of ownership.
Thanks to their anti-adhesive properties and corrosion resistance, GFS tanks require little to no maintenance. Smooth internal walls prevent scaling and bacterial buildup, ensuring stored fire water stays clean and ready for emergency use.
Center Enamel can produce tanks from 20 m³ to 60,000 m³ capacity. Modular design allows easy expansion or relocation if fire protection requirements evolve over time.
With their glossy finish and color flexibility, GFS tanks complement both industrial and urban environments. They are fully recyclable and free from harmful field coatings, aligning with green building and sustainability objectives.
An engineered sealing system using EPDM or silicone gaskets ensures absolute water tightness and airtight protection. The glass surface’s impermeability minimizes evaporation and contamination risks.
Withstanding a broad pH range (1–14) and extreme temperatures, GFS tanks maintain excellent mechanical and aesthetic properties, even in challenging climates or chemical-prone fire safety setups.
GFS Fire Water Tanks serve as critical components of fixed fire suppression systems. They are widely used in:
· Industrial complexes – For power plants, oil refineries, and chemical facilities.
· Commercial buildings – Shopping malls, warehouses, and logistics centers.
· Municipal fire stations – Ensuring ready water supply for firefighting operations.
· High-risk processing zones – Refineries and energy sectors requiring continuous fire readiness.
· Remote infrastructures – Agricultural or mining installations with limited water sources.
By maintaining a constant reserve of pressurized water, GFS tanks play a vital role in protecting life, assets, and critical
