China’s Leading Large-Capacity Water Storage Tank Manufacturer

Center Enamel’s Glass-Fused-to-Steel Tanks — Reliable, Durable, and Globally Trusted Solutions for Water Storage

In today’s rapidly evolving world, reliable access to water is critical for communities, industries, agriculture, and power systems. Whether for municipal potable water supply, industrial process water, environmental buffering, agricultural irrigation, fire protection reserves, or emergency storage applications, large-capacity water storage tanks play a vital role in ensuring the continuity of water services, protecting public health, and supporting economic development.

At the heart of this global need stands Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) — widely recognized as China’s leading large capacity water storage tank manufacturer. With nearly two decades of expertise, a portfolio of nearly 200 patented technologies, advanced manufacturing capabilities, and products certified to international standards, Center Enamel’s Glass-Fused-to-Steel (GFS) tanks provide unmatched performance, durability, and long-term value.

This article explores why Center Enamel is trusted worldwide for large-capacity water storage tanks, how GFS technology redefines tank reliability, and why these tanks are ideal for even the most demanding storage applications.

Center Enamel — A Global Leader in Engineered Tank Solutions

Since its founding in 2008, Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) has grown from a regional manufacturer into a globally recognized supplier of advanced engineered containment systems. While our products cover a wide range of storage needs — including fusion bonded epoxy tanks, stainless steel tanks, galvanized steel tanks, and aluminum geodesic dome roofs — Glass-Fused-to-Steel (GFS) tanks remain our flagship for large-capacity water storage.

By combining technical innovation with manufacturing excellence and global execution capabilities, Center Enamel delivers water storage solutions that perform in demanding conditions and meet stringent regulatory standards worldwide.

Understanding Glass-Fused-to-Steel (GFS) Technology

Glass-Fused-to-Steel (GFS) is a highly advanced tank manufacturing technology that creates a permanent bond between glass and steel. The process involves fusing specially formulated glass enamel onto hot-rolled steel panels at temperatures of 820°C–930°C, resulting in an inorganic, corrosion-resistant surface that is bonded at the molecular level to the steel.

This unique composite material combines the mechanical strength and structural capacity of steel with the chemical inertness and corrosion resistance of glass — making GFS tanks particularly suited to long-term, large-capacity water storage applications.

How GFS Tanks Are Constructed

Steel plates are prepared and cleaned under strict quality control.

Glass enamel coating is applied evenly.

Plates are fired at high temperatures in a kiln.

Enamel forms a permanent metallurgical bond with steel.

Finished panels are precision-cut and assembled into modular tanks on-site.

This controlled manufacturing process yields tanks with performance characteristics far superior to conventional concrete, painted steel, or epoxy-coated systems.

Key Advantages of GFS Large Capacity Water Storage Tanks

1. Exceptional Corrosion Resistance

The fused glass surface forms an impermeable, inert barrier that resists corrosion from water, chemicals, oxygen, and microbial activity — a critical advantage for long-term water storage.

2. Impermeability and Leak Prevention

Unlike many traditional materials, GFS technology creates a liquid- and gas-impermeable surface, significantly reducing the risk of leakage, seepage, or soil contamination.

3. Hygienic Smooth Surface

The smooth, non-porous interior surface prevents biofilm adhesion and sediment buildup, facilitating easier cleaning and helping preserve water quality.

4. Long Service Life and Low Maintenance

GFS tanks are engineered for a service life of 30 years or more, with minimal maintenance requirements compared to concrete, epoxy-coated, or painted steel alternatives.

5. Modular Bolted Panel Assembly

Center Enamel’s modular design enables efficient on-site construction, reduces dependency on skilled welders or concrete crews, and supports installation in remote or constrained locations.

6. Structural Strength and Flexibility

Steel provides reliable structural integrity for large-capacity tanks, while the fused glass surface protects against aggressive conditions and supports consistent performance under load.

International Standards and Certifications

Center Enamel’s GFS large capacity water storage tanks are designed and manufactured in compliance with globally recognized standards, ensuring safety, quality, and performance consistency:

ISO 9001 — International Quality Management System

ISO 45001 — Occupational Health & Safety

ISO 28765 — Glass-Fused-to-Steel Tank Standard

AWWA D103-09 — Steel Water Storage Tank Standard

NSF/ANSI 61 — Safety for Drinking Water Systems

EN 1090 / CE — Structural Compliance

WRAS — Water Safety Certification

FM, LFGB, BSCI — Additional Accessory and Quality Certifications

These certifications demonstrate that Center Enamel’s GFS tanks meet or exceed international engineering and safety benchmarks for water storage infrastructure.

Why GFS Tanks Are Ideal for Large Capacity Water Storage

Large capacity water storage presents unique challenges that GFS technology addresses better than traditional options:

Concrete Tanks

While concrete is durable, it is prone to cracking, leakage, and seepage without extensive joint sealing and maintenance. GFS tanks offer a seamless impermeable solution without the risk of concrete deterioration.

Painted or Epoxy-Coated Tanks

Organic coatings degrade over time under cycling temperatures and moisture exposure. GFS glass enamel is inorganic and permanent, resisting peeling, chalking, or blistering.

Fiberglass or Plastic Tanks

Fiberglass and plastic tanks suffer from UV degradation, creep under load, and limited long-term rigidity. GFS steel provides superior structural performance and longevity.

Applications of GFS Large Capacity Water Storage Tanks

1. Municipal and Public Water Supply

Drinking water reservoirs

Urban and rural water distribution systems

Emergency and drought backup storage

GFS tanks ensure potable water quality with NSF/ANSI 61 compliance, supporting community health and continuity of supply.

2. Industrial Water Storage

Process water supply

Cooling water reservoirs

Boiler feed water storage

Durability and corrosion resistance make GFS tanks ideal for demanding industrial environments.

3. Fire Protection and Safety Reserves

Industrial fire water storage

Airport fire protection reserves

Commercial and municipal firefighting systems

Reliable storage capacity, combined with corrosion-resistant surfaces, supports critical safety infrastructure.

4. Agricultural and Irrigation Water Storage

Irrigation reservoirs

Agricultural water buffering systems

Aquaculture water tanks

GFS tanks support farm irrigation, livestock watering, and water reuse with minimal maintenance.

5. Wastewater and Environmental Management

Equalization basins

Sludge or effluent buffers

Combined sewer overflow containment

The impermeable surface prevents groundwater contamination and supports environmental compliance.
