What is Glass-Fused-to-Steel (GFS)?

Glass-Fused-to-Steel (GFS) is a cutting-edge technology that bonds glass to steel at extremely high temperatures (around 800-900°C). This fusion creates a smooth, non-porous, and highly resistant surface that offers outstanding protection against corrosion and wear in even the harshest environments. The result is a tank with enhanced strength, longevity, and reliability, making it the perfect choice for water storage and waste management.

Why Choose Center Enamel’s Glass-Fused-to-Steel Tanks?

1. Adherence to Industry Standards

Our Glass-Fused-to-Steel tanks are designed and manufactured in strict compliance with AWWA D103 and EN ISO 28765 standards, ensuring that every tank we deliver meets or exceeds the highest quality benchmarks in the industry.

AWWA D103 is a standard established by the American Water Works Association (AWWA) for the design and construction of glass-lined steel tanks. This standard ensures that the tanks are built to last, can withstand the pressures of water storage, and can maintain the integrity of the glass coating.

EN ISO 28765 is an international standard that outlines the requirements for glass-fused-to-steel tanks, focusing on the quality of the enameling process, tank design, and material performance. This standard ensures that the tanks are safe, reliable, and suitable for use in drinking water storage, wastewater treatment, and biogas storage applications.

By adhering to these rigorous standards, we ensure that our tanks are not only safe but also long-lasting and highly durable, delivering excellent value over the long term.

2. Exceptional Corrosion Resistance

The corrosion resistance of Glass-Fused-to-Steel tanks is one of their most significant advantages. The glass enamel coating acts as a protective barrier, preventing any direct contact between the steel and the stored liquids. This makes our tanks highly resistant to corrosive chemicals, acids, salts, and abrasion, making them the ideal solution for harsh environments.

Corrosion resistance ensures that our tanks remain functional even in highly corrosive conditions, reducing the need for frequent maintenance and replacement.

The non-porous surface prevents the growth of harmful bacteria and algae, which is particularly important in water storage and wastewater treatment applications.

This corrosion resistance guarantees that the tanks will have a long service life, offering a cost-effective solution with minimal maintenance needs.

3. Long-Term Durability and Strength

Glass-Fused-to-Steel tanks from Center Enamel are designed for maximum durability. The fusion of glass to steel creates a strong and resilient surface that can withstand extreme environmental conditions and heavy operational demands. Whether exposed to high temperatures, extreme weather, or aggressive chemicals, our tanks are built to perform under the most demanding conditions.

Long service life of 30+ years with minimal maintenance.

High mechanical strength to withstand internal and external pressures.

Resistant to both high and low temperatures, ensuring optimal performance in diverse climates.

The durability of our tanks makes them an excellent investment, ensuring that they provide reliable performance for decades, even in challenging conditions.

4. Modular Design for Customizable Solutions

At Center Enamel, we understand that each project has unique requirements. That’s why our Glass-Fused-to-Steel tanks are designed with modular construction that allows for flexibility and customization. This modular approach makes it easy to expand or reconfigure the tank system as your needs change, without the need for a complete replacement.
