Glass fused bolted steel tanks are made through the process of firing at 820°C-930°C high temperature, the molten glass reacts with the steel plate surface to form an inert and inorganic bond, which combines the strength and flexibility of steel and outstanding corrosion resistance of glass, so Glass-Fused-to-Steel tanks can provide many advantages over standard epoxy or welded painted storage tanks. Glass-Fused-to-Steel technology is the premium coating technology in the storage tanks market, and Glass Fused to Steel tanks are widely used in drinking water, bio-energy, municipal sewage and industrial wastewater treatment etc.
