High Anti-Corrosion GFS Fire Water Tank - Reliable China Suppliers and Factory Solutions
Description
Fire water storage is a special system that remains stationary most of the time, but must be put into immediate use in an emergency. In this situation, attention must be paid to issues such as microbial growth, sediment accumulation, and increased water corrosivity. Due to the material properties of GFS tanks, they can ensure that long-term contact with fire-fighting water without causing corrosion, water pollution, or loss of strength.
The Glass Fused to Steel (GFS) tank is a kind of bolted storage tank made from two materials: glass and steel. High-strength TRS (titanium-rich steel) plates and enamels are perfectly fused at high temperatures to form a highly inert inorganic glaze layer. This coating system has excellent anti-corrosion properties.
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
❓
What is a Glass Fused to Steel (GFS) tank?
A Glass Fused to Steel (GFS) tank is a bolted storage tank manufactured by fusing high-strength TRS (titanium-rich steel) plates with enamel at high temperatures. This process creates a highly inert inorganic glaze layer that provides excellent anti-corrosion protection and long-term durability.
❓
Why are GFS tanks suitable for fire water storage?
GFS tanks are ideal for fire water storage because their glass-fused coating prevents corrosion, water pollution, and strength degradation even during prolonged static storage. They resist microbial growth and sediment accumulation, ensuring the water remains ready for immediate emergency use.
❓
What is the service life of a GFS fire water tank?
GFS fire water tanks have a service life of more than 30 years. The durable enamel coating with a hardness of 6.0 Mohs and a thickness of 250–450 µm ensures long-lasting performance with minimal maintenance requirements.
❓
What pH range can GFS tanks handle?
Standard grade GFS tanks can handle a pH range of 3 to 11, making them suitable for most water storage applications. For more demanding chemical environments, special grade tanks are available that cover a pH range of 1 to 14.
❓
Can GFS tanks be relocated or expanded after installation?
Yes. One of the key advantages of GFS bolted tanks is their flexibility. They can be disassembled, relocated, and reassembled at a new site. The modular bolted design also allows for capacity expansion, making them a cost-effective long-term solution.
❓
What makes the steel substrate of GFS tanks special?
The steel substrate used in GFS tanks is a specially formulated high-strength enamelled steel featuring low carbon and high titanium content. Its mechanical properties — including yield strength, tensile strength, and elongation — significantly exceed those of conventional steel sheets, ensuring both structural integrity and superior coating adhesion.
