Core Manufacturing Excellence and Product Ecosystem
As an industry pioneer that introduced advanced Glass-Fused-to-Steel (GFS) technology to China, Center Enamel operates a massive, modern production base equipped to deliver top-tier containment solutions:
Glass-Fused-to-Steel (GFS) Tanks: Produced by fusing molten glass to high-strength steel plates at extreme temperatures between 820°C and 930°C, this creates an impenetrable molecular bond that completely resists corrosion, abrasion, and UV degradation.
Fusion Bonded Epoxy (FBE) & Bolted Steel Tanks: Engineered for superior chemical resistance and structural flexibility, bolted tanks allow for rapid, weather-independent assembly anywhere in the world.
Aluminum Geodesic Dome Roofs: Lightweight, corrosion-resistant maintenance-free covers that shield stored water from biological contamination, wind, and debris.
Global Compliance and Safety Certifications
Safeguarding public health and municipal water supplies requires strict adherence to global regulatory frameworks. Center Enamel’s water storage tanks meet or exceed the world's most demanding standards:
NSF/ANSI 61 & WRAS: Certifying that materials in contact with drinking water are completely safe, non-toxic, and hygienic.
AWWA D103-09: Complying with American Water Works Association standards for bolted steel water storage.
ISO 9001, ISO 14001, and ISO 28765: Ensuring uncompromising quality control across every stage of manufacturing and export documentation.
