Glass Fused to Steel
Heritage Steel Storage Pvt. Ltd.
designs and manufactures Glass-Fused-toSteel (GFS) Tanks for the storage of potable water, wastewater, industrial liquids, fire water and biogas applications. GFS technology combines the structural strength of steel with the superior corrosion resistance of glass, delivering exceptional durability and long service life.
In this process, glass enamel is permanently fused to the steel surface at high temperature, creating a chemically inert, corrosion-resistant coating with excellent adhesion.
Our Glass-Fused-to-Steel (GFS) designed and manufactured in accordance with applicable AWWA D103, ISO and project-specific engineering requirements, wherever applicable.. These tanks are suitable for both small and large storage capacities and can be customized as per project requirement, site condition, liquid type, and storage volume.
KEY BENEFITS
➤ Excellent corrosion resistance
➤ Modular bolted construction
➤ High structural strength
➤ Long design life
➤ Fast installation
➤ Expandable storage capacity
➤ Hygienic and smooth internal surface
➤ Customized capacity and design available
GLASS-FUSED-TO-STEEL (GFS) TANKS MANUFACTURING PROCESS & TECHNOLOGY
The glass enamel coating is permanently fused to the steel surface at high temperature, producing a chemically inert, highly corrosion-resistant finish with exceptional bond strength. All tanks comply with applicable AWWA D103, ISO standards, and approved project specifications, wherever applicable. AWWA D103, ISO standards and approved project specifications wherever applicable.
PANEL CUTTING & PUNCHING
Steel panels are cut as per tank design. Nut-bolt holes, manholes, nozzles, and required openings are accurately punched for easy site assembly.
SHOT BLASTING / SURFACE PREPARATION
Panels are cleaned through shot blasting to remove rust, dust, scale, and impurities. This helps create a strong bonding surface for glass enamel coating.
PRE-TREATMENT
Panels are prepared before coating to improve surface quality, coating adhesion, and long-term durability.
ENAMELLING PROCESS
A special glass enamel coating is applied on the steel panels to provide corrosion resistance, chemical protection, and smooth surface quality.
FURNACE FIRING / GLASS FUSION
Coated panels are fired at high temperature, where glass fuses with steel and forms a strong protective layer.
INSPECTION & TESTING
Each panel is checked for coating quality, thickness, surface finish, impact resistance, and hole alignment. Testing Includes: Spark Test, Coating Thickness Verification (where applicable), Visual Inspection, and Holiday Test (if applicable), Dimensional Inspection.
PACKING & DISPATCH
After final approval, panels and accessories are safely packed and dispatched to the project site for installation.
