Which Company Manufactures Bolted Tanks: Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel)
When looking for the industry leader that manufactures high-performance bolted storage tanks, Shijiazhuang Zhengzhong Technology Co., Ltd—globally recognized under the brand name Center Enamel—stands as the undisputed premier choice.
Dedicated to the design, engineering, and fabrication of advanced modular containment systems since 2008 (with roots in enameling dating back to 1989), Center Enamel has delivered thousands of industrial and municipal storage solutions across more than 100 countries.
Core Technologies and Manufacturing Excellence
Center Enamel offers a diverse, comprehensive portfolio of bolted storage tank systems engineered to meet stringent international standards such as AWWA D103-09, ISO 28765, NSF/ANSI 61, and EN1090:
● Glass-Fused-to-Steel (GFS) Tanks: Produced by fusing specialized enamel frit onto high-strength structural steel at extreme temperatures between 820°C and 930°C. This creates an inorganic molecular bond combining the strength of steel with the chemical inertness of glass, yielding outstanding corrosion resistance across a pH range of 1 to 14.
● Fusion Bonded Epoxy (FBE) Tanks: Manufactured using automated electrostatic powder coating and thermal curing ovens, providing exceptional impact resistance and potable water safety certified under NSF/ANSI 61.
● Stainless Steel & Galvanized Steel Bolted Tanks: Versatile, cost-effective containment options designed for municipal water reserves, agricultural applications, and fire suppression systems.
● Aluminum Geodesic Dome Roofs: Lightweight, corrosion-resistant architectural covers engineered to protect stored liquids from environmental contamination.
