Center Enamel: The Global Authority in Coated Steel Storage Tanks
For industrial, municipal, and agricultural sectors, the integrity of a storage vessel is the foundation of operational security. Center Enamel stands as the global leader in the design and fabrication of bolted storage tanks, providing premium Glass-Fused-to-Steel (GFS) and Fusion Bonded Epoxy (FBE) solutions. With over 30 years of experience, we deliver storage infrastructure that balances structural strength with superior chemical resistance.
Core Technologies: Why GFS and FBE Lead the Industry
Center Enamel specializes in two primary coating technologies, each engineered to solve specific industrial containment challenges.
Glass-Fused-to-Steel (GFS)
GFS tanks (also known as enamel-coated tanks) are the gold standard for corrosive environments. By firing molten glass onto steel plates at 820°C–930°C, we create a molecular bond that is chemically inert, hard, and highly resistant to abrasion.
Best For: Wastewater treatment, anaerobic digesters, biogas production, and landfill leachate, where hydrogen sulfide ($H_2S$) and low-pH effluents would destroy standard steel.
Key Advantage: A 30+ year design life with minimal to no maintenance.
Fusion Bonded Epoxy (FBE)
FBE tanks utilize a thermoset polymer coating applied electrostatically to steel, creating a durable, impact-resistant shield.
Best For: Potable water storage, fire protection reservoirs, and general industrial applications where high-purity water containment is required.
Key Advantage: Cost-effectiveness and excellent adherence, fully compliant with NSF/ANSI 61 standards.

Why Industry Leaders Choose Center Enamel
Our reputation as a premier manufacturer is built on rigorous engineering standards and global project success.
Finite Element Analysis (FEA): We eliminate guesswork. Every tank is optimized via FEA to withstand site-specific seismic activity, wind loads (up to 250 km/h), and hydrostatic pressure variables.
1500V Holiday Testing: Coating continuity is the lifeblood of a tank. 100% of Center Enamel panels undergo high-voltage holiday testing to ensure the barrier is free of microscopic pinholes.
Synchronized Hydraulic Jacking: Our proprietary installation method assembles tanks from the top down, keeping labor at ground level for improved safety and speed—3x faster than field welding.
Frequently Asked Questions (FAQ)
Q: Why are bolted tanks preferred over welded tanks for industrial storage?
A: Bolted tanks offer factory-controlled coating quality (verified by high-voltage testing), significantly faster site assembly (3x faster than welding), and the ability to relocate or expand the structure, which is not possible with field-welded tanks.
Q: Are Center Enamel tanks suitable for potable water?
A: Yes. Our tanks are certified to rigorous international standards, including NSF/ANSI 61 and WRAS, ensuring they provide a biofilm-resistant, non-toxic environment for drinking water storage.
Q: Can these tanks be used in cold climates?
A: Absolutely. Our tanks are engineered to withstand extreme thermal fluctuations. When paired with appropriate insulation and internal heating systems, they maintain optimal operational temperatures for biogas or water processes in any climate.
Q: How do you ensure the tanks are leak-proof?
A: We use a dual-protection strategy: high-grade EPDM/Silicone sealants applied at every joint combined with precise torque application on every bolt, followed by full hydrostatic testing to confirm 100% leak-proof performance.
Q: Does Center Enamel support global projects?
A: Yes. As of 2023, our tanks have been exported to over 100 countries, including the USA, Australia, Russia, and Brazil. We provide full EPC technical support, from design and manufacturing to installation supervision.
