Global Leading Glass-Fused-to-Steel Tanks Manufacturer: Center Enamel’s Legacy of Quality, Innovation, and Sustainability
For more than three decades, Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) has been a frontrunner in the global storage tank industry, setting benchmarks for quality, technical innovation, and environmental responsibility. As the first manufacturer of Glass-Fused-to-Steel (GFS) tanks in China, Center Enamel has built a worldwide reputation as a trusted provider of durable, high-performance storage solutions for water, wastewater, biogas, and industrial applications.
The Journey of Excellence
Center Enamel’s story began with a mission to pioneer advanced storage solutions for modern industries. The company quickly recognized the potential of glass-fused-to-steel technology—a process combining the structural strength of steel with the durability and chemical resistance of glass—to deliver long-lasting containment solutions.
● 2008 Milestone: Center Enamel launched its first independently developed GFS tank, introducing double-sided enameling technology for hot-rolled steel plates—a pioneering achievement in Asia.
● 2017 Milestone: Successfully fabricated and installed a record-breaking 34.8-meter-high GFS tank, marking another milestone in large-scale storage engineering.
● Global Footprint: Today, with over 150,000 m² of advanced production facilities and a dedicated R&D center, the company exports advanced tank systems to more than 100 countries, including the USA, Australia, Canada, Brazil, South Africa, Malaysia, and the United Arab Emirates.
What Makes GFS Technology Superior
Glass-Fused-to-Steel tanks result from a thermal fusion process in which high-strength steel plates are coated with an inorganic enamel layer and fired at temperatures between 800°C and 900°C. This creates a permanent molecular bond between steel and glass, yielding a non-porous, corrosion-resistant, and structurally robust surface.
This composite material offers unmatched performance advantages over conventional welded steel or concrete tanks:
● Unmatched Corrosion Resistance: The glass layer prevents direct contact between the steel substrate and stored media, delivering exceptional resistance across a wide pH range of 1 to 14.
● Superior Durability: With a design life exceeding 30 years, GFS tanks perform reliably in harsh industrial and environmental conditions.
● Easy Installation and Maintenance: Modular bolted construction ensures rapid on-site assembly, shorter project timeframes, and minimal upkeep costs.
● Environmental Safety: The inert surface properties ensure zero leaching or chemical contamination, making these tanks ideal for potable water and sensitive ecological projects.
● Aesthetic Versatility: Smooth, glossy enamel surfaces resist UV fading and are available in multiple colors to meet architectural design needs.
Center Enamel’s Technological Leadership
At the heart of Center Enamel’s success lies its in-house research and development department, driving continuous industry innovation with nearly 200 patents in enameling technology, coating formulations, and modular assembly systems.
● Proprietary Steel Formulations: Development of specialized Ti-rich steel formulations that enhance enamel bonding and eliminate surface defects like blistering and fish-scaling.
● Advanced Furnace Systems: High-precision industrial furnaces guarantee uniform firing temperatures, ensuring consistent coating thickness and adhesion.
● Precision Engineering: Integration of high-precision CNC machining and laser profiling for seamless on-site structural alignment.
