High-Quality Glass Fused to Steel Tanks by China Suppliers | Durable Corrosion Resistant Storage Solutions from Factory
Description
Bolted steel tanks made of Glass-Fused-to-Steel are widely used for all kinds of storage solutions. Glass fused to steel is a permanent, molecular bond created by fusing a specially formulated silica-based glass enamel to a base sheet of steel at very high temperatures (around 820°C / 1500°F), combines the advantages of both materials — the strength and flexibility of steel and excellent anti-corrosion properties of glass.
LIDA's glass fused to steel (GFS) storage tanks are composed mainly of enamel panel, special sealant and self-locking bolts, etc. The steel plates are overlapped, bolted together and sealed with high performance seals. All the bolt heads are plastic-capped to provide protection against corrosion in the process environment. Mastic is extruded between the panels and the bolt heads seal the bolt shank to prevent contact with process fluids.

Uses of Glass Fused To Steel Tanks
Glass Fused To Steel Tanks are widely used in various industries and serve different purposes in different environments. These tanks are mainly used for:
- Municipal drinking water, sewage treatment, sludge storage, wastewater treatment and anaerobic digestion and biogas.
- Industrial wastewater treatment, storage, anaerobic digestion and biogas, process water storage and bulk solids storage.
- Agricultural slurry storage, on- and off-farm biogas production, storage of livestock feeds such as hay, maize and high-moisture grains, and bulk solids storage.
Renowned for their extended service life and minimal maintenance requirements owing to corrosion resistance and UV stability, glass-fused tanks cater to municipal, industrial, and agricultural needs.
Their superior corrosion resistance, durability and ease of maintenance make them ideal for storing and handling a wide range of liquids, chemicals and gases. Additionally, these glass fused bolted steel tanks can be used for rainwater harvesting, firefighting and storage of various industrial liquids.

Glass Fused To Steel Bolted Tanks Manufacturing Process
Glass-Fused-To-Steel Tank adopts high strength glass fused special steel as the base material, and uses the honing technology at high temperature of 800 degrees Celsius to fuse the anti-corrosion glaze layer with high inertia onto the surface of the base material to make standardized steel plate module. It combines both strength and flexibility of steel and excellent corrosion resistance of glass as well as the perfect impact and abrasion resistance, and that withstands the extreme temperature and harsh weather conditions.
Compared with other tanks (Carbon Steel Welded Tank / Reinforced Concrete Tank), Glass-Fused-To-Steel Tank has achieved breakthrough innovations in materials, anti-corrosion technology and installation methods, and is a kind of advanced storage tank manufacturing technology.
❓ Frequently Asked Questions
Q What is Glass-Fused-to-Steel (GFS) and how is it made?
Glass-Fused-to-Steel is a permanent molecular bond created by fusing a specially formulated silica-based glass enamel to a base sheet of steel at very high temperatures — around 820°C (1500°F). This process combines the mechanical strength and flexibility of steel with the excellent corrosion resistance and chemical inertness of glass, resulting in a highly durable tank material.
Q What industries and applications are GFS tanks suitable for?
GFS tanks are suitable for a broad range of applications including municipal drinking water storage, sewage and wastewater treatment, sludge storage, anaerobic digestion and biogas systems, industrial process water storage, agricultural slurry storage, livestock feed storage, rainwater harvesting, and firefighting water reserves.
Q How long is the service life of a Glass-Fused-to-Steel tank?
With simple and minimal maintenance, GFS tanks are designed to have a service life in excess of 30 years. Their superior corrosion resistance and UV stability ensure long-term performance even in harsh environmental conditions.
Q What are the main advantages of GFS tanks over concrete or welded steel tanks?
Compared to Carbon Steel Welded Tanks and Reinforced Concrete Tanks, GFS tanks offer breakthrough innovations in materials, anti-corrosion technology, and installation methods. Key advantages include faster installation, lower construction environment requirements, excellent anti-corrosion properties, strong temperature adaptability, and the flexibility to be relocated, expanded, or recycled.
Q How are GFS tank panels connected and sealed to prevent leakage?
GFS tank panels are overlapped and bolted together using self-locking bolts with high-performance seals. Mastic sealant is extruded between the panels, and all bolt heads are plastic-capped to prevent corrosion. The bolt shanks are also sealed to prevent any contact with process fluids, ensuring a fully leak-proof structure.
Q What type of steel is used in Glass-Fused-to-Steel tanks?
The steel substrate used in GFS tanks is a special high-strength enamelled steel with low carbon and high titanium content. Its mechanical properties — including yield strength, tensile strength, and elongation — far exceed those of conventional steel sheets, making it an ideal base material for long-lasting, high-performance storage tanks.
