High Safety & Hygiene GFS Potable Water Storage Tanks - China Suppliers & Factory for Durable Solutions
Description
Safety, cleanliness and odorlessness are essential requirements for drinking/potable water storage. Glass-Fused-to-Steel (GFS) tanks perform exceptionally well in meeting these standards.
The inner enamel layer is an inorganic glass coating sintered at a high temperature of 820°C – 930°C. It features stable chemical properties, is non-toxic and odorless, and does not release harmful substances into water, ensuring the safety of drinking water. Its surface is as smooth as glass, making it difficult for bacteria to grow. This greatly reduces microbial adhesion and scaling, is easy to clean, and maintains clear and pure water quality over the long term.
🏅
High-quality products will pass authoritative international certifications such as NSF/ANSI 61 (U.S. Drinking Water Standard), which serves as strong proof of their safety performance.
Uses of Glass Fused To Steel Tanks
Glass Fused To Steel Tanks are widely used in various industries and serve different purposes in different environments. These tanks are mainly used for:
- 🏙️ Municipal: Drinking water, sewage treatment, sludge storage, wastewater treatment and anaerobic digestion and biogas.
- 🏭 Industrial: Wastewater treatment, storage, anaerobic digestion and biogas, process water storage and bulk solids storage.
- 🌾 Agricultural: Slurry storage, on- and off-farm biogas production, storage of livestock feeds such as hay, maize and high-moisture grains, and bulk solids storage.

Frequently Asked Questions (FAQ)
What makes Glass-Fused-to-Steel tanks suitable for drinking water storage?
GFS tanks feature an inner enamel coating sintered at 820°C–930°C, which is non-toxic, odorless, and chemically stable. The ultra-smooth glass-like surface inhibits bacterial growth, reduces scaling, and prevents harmful substances from leaching into the water — making them ideal for safe potable water storage.
What certifications do Glass-Fused-to-Steel tanks hold for drinking water use?
High-quality GFS tanks can obtain NSF/ANSI 61 certification, the authoritative U.S. Drinking Water Standard. This certification confirms that the tank materials do not release harmful contaminants into potable water and meet strict health and safety requirements.
What industries and applications are GFS tanks used for?
GFS tanks serve a wide range of sectors. In municipal applications, they are used for drinking water, sewage and wastewater treatment, and biogas. In industrial settings, they handle process water and bulk solids storage. In agriculture, they are used for slurry storage, biogas production, and storage of livestock feeds such as hay, maize, and high-moisture grains.
What is the steel substrate used in GFS tanks, and why is it special?
The steel substrate used is a special low-carbon, high-strength, high-titanium enamelled steel. Its mechanical properties — including yield strength, tensile strength, and elongation — significantly exceed those of conventional steel sheets, providing superior structural integrity and durability for the tank.
How long is the service life of a Glass-Fused-to-Steel tank, and is maintenance difficult?
GFS tanks are designed for a service life in excess of 30 years. Their enamel coating is highly resistant to corrosion and does not require painting or re-coating. Maintenance is simple compared to concrete or traditional steel tanks, resulting in lower long-term operational costs.
Can Glass-Fused-to-Steel tanks be relocated or expanded after installation?
Yes. One of the key advantages of GFS tanks is their modular, bolted assembly design. This makes them flexible for relocation to different sites, easy to expand by adding additional panels, and even recyclable at the end of their lifecycle — offering significant long-term flexibility compared to concrete tanks.
