What Are Glass-Fused-to-Steel Tanks?
Glass-Fused-to-Steel (GFS) tanks — also known as glass-lined steel or glass-enamel tanks — are a highly advanced storage solution manufactured by fusing specially formulated glass onto steel plates at extremely high temperatures (typically 820°C–930°C). This process creates a permanent, inorganic bond between the glass and steel, producing a composite surface with remarkable properties.
How GFS Technology Works
During production:
Steel plates are cleaned and prepped.
Powdered glass coating is applied.
Plates are heated in kilns at 820°C–930°C.
The molten glass chemically bonds to the steel.
Enamelled panels are precision-cut and fabricated for tank assembly.
The result is a storage tank that couples the structural advantages of steel with the chemical inertness and corrosion resistance of glass — making GFS tanks exceptionally suited for long-term storage of water and various liquids.
Why Choose GFS Steel Storage Tanks?
Glass-Fused-to-Steel tanks outperform traditional materials such as concrete, painted steel, epoxy-lined tanks, and fiberglass in virtually every performance category. Here’s why:
1. Superior Corrosion Resistance
The glass enamel coating provides a chemically inert surface that resists corrosion from water, effluent, chemicals, and atmospheric contaminants. Unlike organic coatings (e.g., paint or epoxy), fused glass does not peel, crack, or blister over time — ensuring decades of service life.
2. Impermeability to Liquids and Gases
GFS tanks create a complete barrier that prevents water, wastewater, and other liquids from permeating the tank walls. They also prevent gas escape and odor emission — a critical attribute for both potable water and wastewater applications.
3. Long Service Life (≥ 30 Years)
Designed for longevity, GFS tanks require minimal maintenance and deliver exceptional lifecycle value. Their corrosion resistance and impermeability translate into a service life exceeding 30 years in many projects.
4. Hygienic Smooth Interior
The glossy, inert enamel surface resists adhesion of sediments, biofilm, and contaminants — reducing cleaning requirements and helping preserve water quality in potable and process applications.
5. Enhanced Structural Strength
GFS tanks leverage steel’s mechanical strength, enabling them to withstand hydrostatic pressure, seismic forces, wind loads, and thermal cycling without deformation.
6. Modular Bolted Assembly
Unlike welded or poured concrete tanks, GFS tanks use modular bolted panel construction that simplifies transport, accelerates onsite assembly, and supports expansion or relocation if needed.
