What Are GFS Tanks?

Glass-Fused-to-Steel (GFS) tanks are created by fusing molten glass to steel at high temperatures, creating a strong, durable, and corrosion-resistant coating. This fusion of materials ensures that GFS tanks offer both the robustness of steel and the chemical resistance of glass, making them suitable for a variety of harsh environments and demanding applications.
