When it comes to safe, long-lasting water storage, Glass Fused to Steel Tanks (GFtS) stand out as one of the most reliable options available. Combining the strength of steel with the corrosion resistance of glass, these tanks are ideal for storing drinking (potable) water in municipal, industrial, and rural applications.
What Are Glass Fused to Steel Tanks?
Glass Fused to Steel Tanks are made by fusing a layer of glass to a steel panel at high temperatures, typically around 850°C. The result is a strong, inert coating that protects the steel from corrosion, chemicals, and weather conditions.
This fusion process produces a smooth, hard surface that is:
- Non-porous.
- Highly durable.
- Safe for storing potable water.
Key Benefits of Glass Fused to Steel Tanks
- Exceptional Corrosion Resistance: The fused glass surface is immune to rust, corrosion, and UV degradation. This makes these tanks especially suitable for storing drinking water over the long term, even in harsh climates.
- Long Lifespan: With proper maintenance, Glass Fused to Steel Tanks can last 30 years or more. The durable coating prevents internal and external damage, reducing the need for frequent replacements.
- Hygienic and Safe: The glass lining is non-toxic and biologically inert, ensuring the water stays clean and safe for human consumption. Most GFtS tanks meet NSF/ANSI 61 and AWWA standards for potable water.
- Quick Installation: Modular construction allows for fast on-site assembly. Pre-fabricated steel panels and bolted connections reduce labor time and disruption.
- Low Maintenance: The tough surface resists scaling and buildup. It’s also easier to clean and less prone to algae growth compared to concrete or plastic tanks.
Common Applications
- Municipal drinking water reservoirs.
- Emergency and rural water supply.
- Industrial process water.
- Agricultural irrigation with potable-grade standards.
- Fire suppression systems.
