Water Supply Tanks: Advanced Glass-Fused-to-Steel Solutions by Center Enamel
Reliable and safe water supply infrastructure is fundamental to public health, urban development, industrial growth, and emergency preparedness. As global demand for clean and secure water storage continues to rise, the need for durable, hygienic, and long-lasting tank solutions has never been greater. Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) delivers world-class Glass-Fused-to-Steel (GFS) Water Supply Tanks, providing a proven, high-performance solution for municipal, industrial, agricultural, and emergency water storage applications worldwide.
Since its establishment in 2008, Center Enamel has grown into the leading bolted storage tank manufacturer in Asia, exporting premium water storage systems to more than 100 countries and earning global recognition for quality, innovation, and reliability.
Why Glass-Fused-to-Steel Tanks Are Ideal for Water Supply Storage
Water supply tanks must meet stringent requirements for safety, corrosion resistance, impermeability, and long service life. Traditional welded steel tanks, concrete tanks, and organic-coated tanks often face challenges such as corrosion, cracking, leakage, and high maintenance costs over time.
Glass-Fused-to-Steel technology offers a superior alternative. By fusing molten glass to high-strength steel plates at temperatures of 820°C–930°C, Center Enamel creates a permanently bonded, inorganic coating that combines the flexibility and strength of steel with the exceptional corrosion resistance of glass. This unique fusion delivers a smooth, non-porous, and chemically inert surface that is perfectly suited for potable and treated water storage.
Compared with fusion-bonded epoxy tanks or conventional welded steel tanks, GFS tanks provide longer service life, higher reliability, and lower lifecycle costs.
Center Enamel: Global Leader in GFS Water Supply Tanks
Center Enamel is widely recognized as:
With a dedicated enameling R&D team and nearly 200 patented enameling technologies, Center Enamel continues to advance GFS tank performance. A major technological milestone is the company’s double-sided enameling technology for hot-rolled steel plates, which ensures comprehensive corrosion protection on both internal and external tank surfaces—critical for water supply applications exposed to varying environmental conditions.
Certified to International Drinking Water and Engineering Standards
Quality assurance and regulatory compliance are essential for water supply infrastructure. Center Enamel’s Glass-Fused-to-Steel water supply tanks are designed, tested, and manufactured in strict accordance with leading international standards, including:
In addition, Center Enamel is certified by ISO 9001, ISO 45001, CE/EN1090, WRAS, NSF 61, FM, FDA, LFGB, ROHS, and BSCI, ensuring global acceptance and compliance for potable water storage projects.
Technical Advantages of GFS Water Supply TanksExceptional Corrosion Resistance
The glass coating provides outstanding resistance to corrosion, acids, and alkalis. With a standard pH range of 3–11 and optional resistance from pH 1–14, GFS tanks perform reliably in a wide variety of water qualities and environmental conditions.
Hygienic and Safe for Potable Water
The smooth, glossy, and inert glass surface prevents bacterial growth, biofilm formation, and contamination, ensuring long-term water quality and safety for drinking water applications.
Superior Impermeability
GFS tanks are completely gas- and liquid-impermeable, eliminating the risk of leakage and protecting valuable water resources.
High Mechanical Strength and Durability
With an adhesion strength of 3,450 N/cm², excellent impact resistance, and a hardness rating of 6.0 (Mohs), GFS tanks maintain structural integrity even under challenging operational loads.
Long Service Life
Designed for a service life of 30 years or more, Center Enamel’s water supply tanks deliver exceptional long-term value with minimal maintenance requirements.
Modular Bolted Design
The modular bolted structure enables fast transportation, rapid on-site installation, and easy expansion or relocation, making GFS tanks ideal for both urban and remote water supply projects.
