Understanding Glass Fused to Steel Technology

GFS tanks are constructed from high-quality steel panels coated with a specially formulated glass enamel layer fired at temperatures around 830°C to 850°C. This fusion bond creates a glass-ceramic coating that chemically and mechanically adheres to steel, resulting in a composite material renowned for excellent corrosion resistance, durability, and sanitary properties.

Unlike conventional steel tanks that require periodic repainting and are susceptible to rust, GFS tanks have a non-porous, inert glass surface on both the interior and exterior, protecting them from contamination, microbial growth, and chemical attack

Key Advantages of GFS Fresh Water Tanks

1. Exceptional Corrosion Resistance

The glass coating forms an impervious barrier preventing corrosion caused by water, chlorine, and microbial activity, extending tank life to 30+ years with minimal maintenance.

2. Hygienic and Safe Water Storage

The smooth glass surface inhibits algae and bacterial growth, ensuring stored water remains clean, safe, and pleasant in taste and odor.

3. Durable and Impact Resistant

The fusion of glass and flexible steel allows the tank to withstand mechanical impacts, thermal expansion, UV radiation, and environmental stress without cracking.

4. Water Impermeability and Leak Resistance

GFS tanks exhibit zero permeability to water and vapor, preventing leaks and contamination from external sources.

5. Modular and Scalable Construction

Bolted panel designs allow easy factory-controlled manufacturing and rapid onsite assembly to exact client specifications with flexibility for future expansion.

6. Low Life-Cycle Cost

Reduced maintenance, long service life, and rapid installation lower total ownership costs compared to concrete or plastic tank

Design Features and Components

· Panels: Hot-rolled steel plates coated on both sides with 0.25 to 0.45 mm fused glass enamel provide strength and corrosion protection.

· Bolted Construction: Precision-cut panels are bolted with chemical-resistant gaskets, ensuring watertight and structurally sound joints without the need for welding onsite.

· Roof Systems: Aluminum alloy domes, geodesic or membrane roofs designed for weather resistance, UV protection, and minimized contamination ingress.

· Foundations and Supports: Engineered for local soil conditions, seismic loads, and wind forces.

· Accessories: Manholes, ladders, level gauges, vents, and instrumentation tailored to operational requirements.

· Surface Finish Options: Available in a variety of colors and coatings for external durability and aesthetic requirements.

Applications of GFS Fresh Water Tanks

· Municipal Water Supply: Reliable storage for potable water in cities, towns, and rural communities.

· Fire Protection: Dedicated water reserves compliant with NFPA standards for firefighting systems.

· Agricultural Water Management: Irrigation water reservoirs in farms and plantations ensuring sustainable water use.

· Industrial Process Water: Safe storage for process water requiring purity and contamination prevention.

· Emergency Water Storage: Resilient tanks for disaster preparedness and humanitarian aid water supplies.

· Rainwater Harvesting Systems: Hygienic storage preventing contamination and algae growth.
