EPC and technical integration services
The company’s global success is backed by nearly 200 patented technologies, extensive R&D, and an advanced manufacturing base of more than 150,000 square meters.
What Makes Glass-Fused-to-Steel (GFS) Special?
Glass-Fused-to-Steel technology is the heart of Center Enamel’s global leadership. In a high-temperature furnace, specially formulated glass frit is fused to high-strength steel plates at temperatures between 850°C and 930°C, creating a composite material that combines the strengths of both glass and steel:
• Structural Strength of Steel
Provides rigidity, load-bearing capacity, and resistance to external forces such as wind, seismic impact, and thermal cycles.
• Corrosion Resistance of Glass
Glass is chemically inert, offering superior protection against rust, chemical attack, moisture, and aggressive industrial environments.
• Smooth, Non-Porous Surface
Prevents bacterial growth, reduces material adhesion, and improves sanitation—making it ideal for potable water, food-grade storage, and wastewater treatment.
• Low Life-Cycle Costs
With a typical service life exceeding 30 years and minimal maintenance requirements, GFS tanks significantly reduce the total cost of ownership.
