China’s Leading GLS Tank Manufacturer: A Global Storage Solutions Pioneer — Center Enamel
In an era where industrial infrastructure, municipal utilities, biogas projects, and water treatment facilities demand flawless storage solutions, Shijiazhuang Zhengzhong Technology Co.,Ltd has risen as a global benchmark for excellence, innovation, and reliability in tank manufacturing. Established in 1989, Center Enamel has continually evolved from a regional enamel products factory into one of the most respected Glass-Fused-to-Steel (GFS/GLS) storage tank manufacturers in China and across the world.
What Are GLS (Glass-Lined Steel) Tanks?
Before delving into the company’s leadership and legacy, it’s essential to understand the product that has become Center Enamel’s hallmark.
Glass-Lined Steel (GLS) tanks, also known as Glass-Fused-to-Steel (GFS) tanks, embody the fusion of two powerful materials — the mechanical strength of steel and the corrosion resistance of glass. Through a specialized high-temperature enameling process, molten glass bonds permanently with steel substrates, creating surfaces that are:
Highly corrosion resistant even in aggressive-medium environments
Smooth and inert, preventing bacterial growth
Easy to clean and maintain
Durable with service lives in excess of 30 years
Economical and modular, thanks to bolted assembly design
This unique combination makes GLS tanks suitable for potable water storage, wastewater treatment systems, biogas containment, industrial effluents, agricultural irrigation systems, petrochemical operations, and more.
A Legacy of Innovation: Center Enamel’s Story
Founded in 1989, Center Enamel began as a manufacturer of enamel products in Shijiazhuang, Hebei Province, China. Over the decades, the company shifted its strategic focus to storage tanks — pioneering enamel-fused technologies long before many competitors entered the market.
Key milestones include:
1993: Establishment of an R&D department dedicated to enamel formula development
1994: First national patent for enamel frit composition — a critical breakthrough in enamel quality
2004: Launch of the first glass-fused-to-steel tank production line in China
2006: Development of specialized steel optimized for enameling in collaboration with Angang Group
2008: Delivering GLS tanks for projects including the Beijing Olympic wastewater treatment infrastructure
2015 and beyond: Expansion into the North American and Australian markets, building global partnerships and exporting tanks to more than 100 countries worldwide
This rich history reflects Center Enamel’s commitment to innovation, quality, and global competitiveness — transforming a local Chinese manufacturing enterprise into a globally recognized industrial brand.
