High Safety & Hygiene GFS Potable Water Storage Tank - China Suppliers & Factory Direct Products
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.
Material Characteristics of Glass-Fused-to-Steel Tanks
Low Carbon, High Strength, High Titanium
The steel substrate employed in the construction of glass-fused-to-steel tanks is a special high strength enamelled steel with a unique design and superior properties. Its mechanical properties, including yield strength, tensile strength, and elongation, far exceed those of conventional steel sheets.

Frequently Asked Questions
Q
What makes Glass-Fused-to-Steel tanks suitable for drinking water storage?
A
GFS tanks feature an inner enamel layer sintered at 820°C–930°C, which is non-toxic, odorless, and chemically stable. The glass-smooth surface resists bacterial growth and scaling, ensuring long-term water purity and safety for potable water applications.
Q
What international certifications do GFS tanks hold for drinking water safety?
A
High-quality GFS tanks can pass NSF/ANSI 61, the U.S. Drinking Water Standard. This certification confirms that the tank materials do not leach harmful substances into water, providing authoritative proof of safety performance.
Q
What industries and applications are Glass Fused To Steel Tanks used in?
A
GFS tanks serve municipal (drinking water, sewage, sludge, wastewater, biogas), industrial (wastewater treatment, process water, bulk solids), and agricultural sectors (slurry storage, biogas production, livestock feed storage).
Q
What type of steel is used in the construction of GFS tanks, and why is it special?
A
GFS tanks use a low carbon, high strength, high titanium enamelled steel substrate. This specially engineered material offers superior yield strength, tensile strength, and elongation far exceeding those of conventional steel sheets, making it ideal for demanding storage applications.
Q
How long is the service life of a Glass-Fused-to-Steel tank, and how easy is it to maintain?
A
GFS tanks are designed for a service life in excess of 30 years. Their enamel surface is easy to clean and highly resistant to corrosion, requiring minimal maintenance compared to conventional concrete or standard steel tanks.
Q
Can GFS tanks be relocated or expanded after installation?
A
Yes. One of the key advantages of Glass-Fused-to-Steel tanks is their modular, bolt-together design, which allows for flexible relocation, capacity expansion, and even recycling of components — making them a highly adaptable long-term investment.
