Glass-Fused-to-Steel Technology for Rainwater Storage
Center Enamel’s GFS tanks are built using high-temperature enamel fusion technology, where molten glass is fired onto hot-rolled steel plates at 820°C–930°C. This process creates a durable metallurgical bond that merges the strength and flexibility of steel with the corrosion resistance of glass, producing tanks that can withstand decades of exposure to water and environmental elements.
Key benefits of GFS technology for rainwater storage include:
