China’s Leading Modular Tank Manufacturer

Glass-Fused-to-Steel (GFS) Solutions by Center Enamel for Global Water and Waste Containment

In today’s world, storage solutions must meet far more than simple containment requirements. Increasing consumption, population growth, rising environmental standards, and stringent safety regulations demand storage tanks that are versatile, durable, corrosion-resistant, environmentally compliant, and long-lasting. This is where Center Enamel’s Glass-Fused-to-Steel (GFS) modular tanks set the world standard.

As a pioneer in modular tank systems and one of Asia’s most experienced manufacturers since 2008, Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) has continuously advanced engineered tank technologies. With a portfolio of products exported to more than 100 countries worldwide, Center Enamel has become recognized globally for delivering high-quality, customizable, and scalable modular tank solutions that address critical needs across water, wastewater, industrial liquids, fire protection, agriculture, energy, and environmental infrastructure.

In this article, we explore why Center Enamel is China’s leading modular tank manufacturer, how GFS modular tanks outperform traditional alternatives, and how these solutions support sustainable infrastructure development around the world.

Center Enamel: A Global Leader in Modular Tank Solutions

Since its founding in 2008, Center Enamel has focused on the design and fabrication of engineered storage systems. While the company’s expertise spans multiple tank technologies—such as fusion bonded epoxy, stainless steel, and galvanized steel—its most transformative innovation has been in Glass-Fused-to-Steel (GFS) modular tanks.

Why Center Enamel Stands Out

Nearly 20 years of industry experience

First manufacturer in China to independently develop double-sided enameling technology

Nearly 200 patented enameling technologies

Exported to more than 100 countries across all continents

Products certified to a wide range of global standards

Advanced R&D and precision manufacturing capacity

Comprehensive EPC and after-sales support

Center Enamel is not simply a manufacturer but an innovative solutions provider—delivering modular tank systems that meet the evolving demands of modern infrastructure projects.

What Is a Modular Tank?

A modular tank is a storage system designed from prefabricated panels and components that are manufactured in controlled factory conditions and then assembled on-site. Unlike traditional monolithic tanks (such as cast-in-place concrete or welded steel tanks), modular tanks:

Are built using standardized or customizable panels

Allow for fast on-site assembly

Can be scaled or expanded easily

Enable cost-efficient transportation and installation

Simplify inspection and maintenance

When combined with Glass-Fused-to-Steel (GFS) technology, modular tanks become a superior solution for a wide range of containment applications involving water, wastewater, industrial liquids, biogas, fire protection, agriculture water, and more.

The Strength of Glass-Fused-to-Steel (GFS) Technology

GFS tanks are fabricated by fusing specially formulated glass onto steel plates at extremely high temperatures (820°C–930°C). This results in a metallurgical bond that produces an exceptionally smooth, inert, and corrosion-resistant surface directly on the steel substrate.

Key Benefits of GFS Technology

Feature Advantage

Corrosion Resistance Outperforms epoxy and paint coatings in harsh environments

Liquid & Gas Impermeability Prevents seepage and soil/groundwater contamination

Hygienic & Easy to Clean Smooth, non-porous surface minimizes biofilm and sediment buildup

Long Service Life ≥30 years of reliable performance

Low Maintenance Minimal operational cost

High Structural Strength Steel provides mechanical integrity

GFS represents the ideal marriage of steel strength and glass corrosion resistance—producing modular tanks that maintain integrity under aggressive chemical conditions, heavy use, and long utility life.

Global Standards and Certifications

Center Enamel’s modular GFS tank systems are engineered and manufactured to meet internationally recognized codes, ensuring performance, quality, and safety.

Key certifications include:

ISO 9001 – Quality management system

ISO 45001 – Occupational health and safety

ISO 28765 – GFS tank standard

NSF/ANSI 61 – Drinking water component safety

EN1090 / CE Certification – Structural compliance

WRAS, FM, LFGB, BSCI – Accessory and compliance certifications

Compliance with these global standards ensures that Center Enamel’s modular tanks are accepted and trusted in rigorous municipal, industrial, commercial, and energy markets around the world.

Modular GFS Tanks vs. Traditional Tank Solutions

Modular GFS tanks offer distinct advantages compared with traditional containment solutions:

Versus Concrete Tanks

Concrete can crack, leak, and deteriorate under corrosive load

GFS modular tanks are resistant to chemical attack and impermeable

GFS enables faster site assembly with less civil construction

Versus Welded Steel Tanks

Welded tanks require extensive onsite labor and field coatings

GFS panels arrive factory-controlled and bolt together quickly

Field welding and post-coating inspections are minimized

Versus Epoxy-Coated or Painted Tanks

Organic coatings can peel, chalk, and degrade over time

GFS coatings are fused at high temperature and do not peel

Surface longevity is significantly improved

These comparisons highlight why modular GFS tanks are increasingly specified for demanding applications in water, wastewater, industrial liquids, and environmental containment.

Applications of GFS Modular Tanks

Center Enamel’s modular GFS tanks are engineered to serve a broad spectrum of storage and containment applications:

1. Drinking Water Storage

Ensuring potable water availability is a critical priority for cities, rural communities, and emergency preparedness systems. GFS modular tanks provide:

Corrosion-free storage

Hygienic surfaces for drinking water

Compliance with NSF/ANSI 61 and WRAS

Reliable performance in municipal water systems

2. Wastewater and Sewage Treatment

Wastewater systems contain aggressive chemicals, suspended solids, and variable pH conditions. GFS modular tanks are ideal for:

Equalization and buffer tanks

Primary and secondary clarifiers

Sludge holding and treatment tanks

Industrial wastewater containment

The impermeability and corrosion resistance of GFS surfaces ensure longevity and low maintenance in these demanding applications.

3. Fire Water Storage

Fire protection systems require reliable storage reserves that remain ready when needed. GFS modular tanks:

Withstand environmental exposure without degradation

Provide dependable fire water reserves for industrial and commercial sites

Integrate with firefighting distribution systems

4. Industrial Liquid Storage

From coolant reservoirs and process water to industrial effluents and chemical storage, GFS modular tanks deliver durability and performance in harsh operating environments.

5. Biogas and Anaerobic Digestion Systems

Waste-to-energy installations and wastewater plants that include anaerobic digestion benefit from:

GFS tank resistance to H₂S and acidic conditions

High operational stability

Reduced emissions and odor control

6. Agricultural Water and Irrigation Storage

For irrigation, livestock watering, aquaculture, and rural water systems, GFS modular tanks provide dependable storage solutions that resist corrosion and biological fouling.

7. Dry Bulk and Specialty Storage

GFS tanks can be adapted for dry bulk materials when combined with appropriate internal coatings and access options, showing the versatility of modular design.
