High Safety & Hygiene GFS Potable Water Storage Tanks - Durable Solutions from China Suppliers & Factory
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.
🏅 Certified to NSF/ANSI 61 — U.S. Drinking Water Standard
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
Q
What makes Glass-Fused-to-Steel tanks suitable for drinking water storage?
GFS tanks feature an inner enamel layer — an inorganic glass coating sintered at 820°C–930°C — that is non-toxic, odorless, and chemically stable. It does not release any harmful substances into water, and its ultra-smooth surface inhibits bacterial growth and scaling, ensuring long-term water purity.
Q
Are Glass-Fused-to-Steel tanks certified for potable water use?
Yes. High-quality GFS tanks are certified to NSF/ANSI 61, the U.S. Drinking Water Standard. This internationally recognized certification confirms that the tank materials do not contaminate drinking water and meet strict safety requirements.
Q
What industries and applications are GFS tanks used in?
GFS tanks serve a broad range of sectors including municipal (drinking water, sewage and wastewater treatment, sludge and biogas storage), industrial (process water, wastewater, anaerobic digestion), and agricultural applications (slurry storage, biogas production, livestock feed storage).
Q
What are the key material characteristics of GFS tank steel?
The steel substrate used is a specially engineered high-strength enamelled steel characterized by low carbon content, high strength, and high titanium composition. Its yield strength, tensile strength, and elongation significantly surpass those of conventional steel sheets, ensuring durability and structural integrity.
Q
How long is the service life of a Glass-Fused-to-Steel tank?
With simple and straightforward maintenance, GFS tanks are designed to deliver a service life in excess of 30 years. Their excellent anti-corrosion properties and durable enamel coating contribute to this exceptional longevity even in demanding environments.
Q
Can GFS tanks be relocated or expanded after installation?
Yes. One of the key advantages of Glass-Fused-to-Steel tanks is their modular, bolt-together construction, which makes them highly flexible. They can be disassembled and relocated, expanded in capacity, or recycled at the end of their operational life — offering significant long-term value.
