China GFS Tanks for Municipal Wastewater Projects - Reliable Suppliers and Quality Factory Solutions
Description
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 and is the best choice for municipal wastewater treatment project.
Municipal wastewater is a complex mixture characterized by large volume, relatively consistent water quality, good biodegradability, but containing suspended solids, nitrogen and phosphorus, microorganisms, and potentially corrosive gases. GFS bolted tanks have become a classic choice for municipal wastewater storage tanks because their electroplated enamel surface can perfectly solve corrosion, vapor phase corrosion, and coefficient wear simultaneously, and is smooth and not prone to scaling.
Glass fused to steel is a permanent, molecular bond created by fusing a specially formulated silica-based glass enamel to a base sheet of steel at very high temperatures (around 820°C / 1500°F), combines the advantages of both materials -- the strength and flexibility of steel and excellent anti-corrosion properties of glass.
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 is a Glass-Fused-to-Steel (GFS) tank?
A GFS tank is a bolted storage tank constructed from high-strength titanium-rich steel (TRS) plates and silica-based glass enamel. These materials are fused together at temperatures around 820°C (1500°F) to create a highly inert inorganic glaze layer that combines the strength of steel with the anti-corrosion properties of glass.
Q: Why are GFS tanks ideal for municipal wastewater treatment?
Municipal wastewater is highly complex and corrosive. GFS bolted tanks are the classic choice because their enamel surface provides excellent protection against corrosion, vapor phase corrosion, and wear. Additionally, the surface is smooth and highly resistant to scaling.
Q: What are the key material characteristics of the steel substrate used?
The substrate is a specialized low-carbon, high-strength, high-titanium enamelled steel. Its mechanical properties—including yield strength, tensile strength, and elongation—far exceed those of conventional steel sheets.
Q: What is the typical service life and hardness of GFS tanks?
GFS tanks feature a coating hardness of 6.0 Mohs and offer a long service life of more than 30 years with simple maintenance requirements.
Q: What industries and applications use Glass-Fused-to-Steel tanks?
They are widely used for municipal drinking water and wastewater treatment, industrial process water and bulk solids storage, and agricultural applications like slurry storage and biogas production.
Q: What installation advantages do GFS tanks offer?
GFS tanks allow for fast installation and a short construction period. They have low construction environment requirements, strong temperature adaptability, and are highly flexible for relocation, expansion, and recycling.
