Salt Water Tanks with Glass-Fused-to-Steel Technology
Enduring, Corrosion-Resistant Solutions by China’s Leading Water Storage Tank Manufacturer — Center Enamel
Salt water — whether used for aquaculture, marine process water, desalination systems, industrial cooling systems, or coastal infrastructure — poses significant challenges to traditional water storage materials. Chlorides and saline solutions accelerate corrosion, compromise structural integrity, and degrade coatings, leading to costly maintenance and premature failure.
For these demanding applications, Glass-Fused-to-Steel (GFS) tanks represent one of the most advanced and durable solutions available. Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) has emerged as China’s leading manufacturer of salt water storage tanks using GFS technology, offering engineered solutions that deliver long-lasting performance, corrosion resistance, and water quality integrity for salt water storage needs around the world.
With nearly two decades of industry leadership, advanced enameling technology, global certifications, and a presence in over 100 countries, Center Enamel stands at the forefront of water storage innovation.

The Challenge of Storing Salt Water
Salt water storage presents a unique set of engineering challenges:
Highly corrosive environment: Chloride ions aggressively attack conventional steel and concrete surfaces.
Material deterioration: Salt water can rapidly degrade coatings and structural materials.
Water quality concerns: Contamination or leaching from tank surfaces can compromise stored water.
Maintenance requirements: Frequent repair and recoating cycles increase lifecycle cost.
Environmental and safety risk: Leaks or tank failures pose environmental hazards in coastal or marine settings.
To overcome these challenges, a tank material must combine structural strength with chemical inertness and long-term corrosion protection — attributes inherent to Glass-Fused-to-Steel (GFS) technology.
What Is Glass-Fused-to-Steel Technology?
Glass-Fused-to-Steel tanks are created by fusing a specially formulated glass coating onto high-tensile steel plates in high-temperature kilns (typically between 820°C and 930°C). The molten glass chemically bonds with the steel surface to form a permanent, inorganic, impervious coating that cannot peel, blister, or separate — even under extreme conditions.
Why GFS Is Ideal for Salt Water Storage
Glass-Fused-to-Steel combines the best attributes of steel and glass:
High structural strength (from steel)
Outstanding corrosion resistance and chemical stability (from glass)
Smooth, non-porous, inert interior surfaces
Impermeability to gas and liquid
Resistance to biological and mineral scaling
Minimal maintenance requirements
Long service life (30+ years)
These features make GFS tanks far superior to conventional alternatives such as painted steel, epoxy-lined steel, concrete, or fiberglass in salt water environments.
Advantages of Glass-Fused-to-Steel Salt Water Tanks
1. Exceptional Corrosion Protection
Salt water is notoriously corrosive, especially to carbon steel and concrete. GFS tanks are protected by a fused glass layer that resists chloride attack, oxidation, and pitting. This results in far longer operational life and dramatically reduced maintenance.
2. Hygienic, Smooth, Non-Porous Interior
The interior GFS surface is smooth and non-adhesive, preventing salt and mineral buildup, biological growth (e.g., algae), or bacterial adhesion. This aids water quality and reduces cleaning needs.
3. Leak-Proof Performance
The glass layer is completely impermeable to both gases and liquids, safeguarding stored salt water from contamination and preventing soil or groundwater infiltration.
4. Structural Strength and Durability
Glass-Fused-to-Steel tanks leverage the mechanical strength of steel while being protected by an inert glass coating — a combination that performs reliably under both static water loads and dynamic environmental stressors.
5. Low Maintenance and Long Service Life
Unlike organic coatings that deteriorate over time, the fused glass bond provides decades of reliable protection with minimal upkeep, lowering total lifecycle costs.
6. Modular Bolted Design
Center Enamel’s GFS tanks use modular bolted construction, enabling:
Efficient on-site assembly
Reduced construction time
Flexibility for expansion or relocation
Delivery to remote or constrained sites

Diverse Applications of Salt Water Tanks
Center Enamel’s GFS salt water tanks are used in a wide range of applications that require corrosion-resistant, long-lasting containment:
1. Aquaculture and Marine Farming
Salt water fish farms, shrimp farms, and seaweed cultivation systems require tanks that withstand high salinity without corroding — a perfect fit for GFS technology.
2. Desalination Plants
GFS tanks provide reliable storage for intake salt water, brine solutions, and treated water in desalination processes.
3. Industrial Cooling and Process Water
Manufacturing facilities, petrochemical plants, and power generation facilities use large volumes of salt water for cooling or processing; GFS tanks provide durable storage.
4. Coastal Infrastructure and Port Facilities
Ports, marinas, and coastal cities store salt water for firefighting, ballast systems, and utility water — requiring tanks that resist corrosion from marine atmospheres.
5. Landscaping and Irrigation
Salt-tolerant landscaping systems and irrigation networks benefit from corrosion-resistant storage that maintains water quality over time.
6. Emergency & Backup Salt Water Reserves
In coastal disaster response planning, reliable salt water reserves may be needed for utilities, firefighting, or industrial purposes.
GFS Tanks vs. Traditional Alternatives
GFS vs. Concrete
Concrete tanks can crack, lose structural integrity, and suffer from chloride penetration — a known issue in marine environments. GFS tanks, by contrast, are unaffected by chloride ingress and maintain structural soundness over decades.
GFS vs. Painted/Coated Steel
Paint and epoxy coatings tend to break down over time due to thermal cycling, abrasion, and salt exposure. Glass-fused coatings are inorganic, bonded at high temperature, and resist degradation.
GFS vs. Fiberglass
Fiberglass can delaminate and degrade under high stress, impact, or temperature variations. GFS tanks combine steel strength with glass durability, offering superior mechanical performance.
