Center Enamel provides high-performance galvanized steel fish ponds engineered for intensive aquaculture and Recirculating Aquaculture Systems (RAS). Utilizing Z275 hot-dip galvanized steel and food-grade BPA-free liners, these modular tanks offer superior structural integrity, UV resistance, and rapid on-site assembly. Designed with a 1.5x hydrostatic safety factor, Center Enamel tanks provide a durable, bio-secure alternative to concrete or plastic ponds for global seafood production.
Feature | Technical Specification | Operational Benefit |
Steel Grade | High-Tensile Carbon Steel | Resists hydrostatic pressure without bulging. |
Coating Spec | Hot-Dip Galvanized (Z275 - 600g/m²) | 15–20+ years of rust-free service life. |
Liner Safety | Food-Grade PVC/TPU (BPA-Free) | Zero chemical leaching; Phthalate-free. |
Safety Factor | 1.5x Hydrostatic Load | Zero-failure structural engineering. |
Compliance | AWWA D103-09, ISO 28765 | Meets international industrial benchmarks. |
In modern aquaculture, the material interface is the first line of defense against pathogens. Unlike porous concrete or mud-bottomed ponds, Center Enamel uses non-porous, food-grade liners.
● Non-Leaching Standards: Our liners are certified BPA-free and Phthalate-free, preventing endocrine-disrupting chemicals from entering the water column.
● UV Stability: High-concentration UV stabilizers prevent the liner from becoming brittle or shedding microplastics into the ecosystem, a critical requirement for 2026 environmental standards.
Maintaining stable water temperatures is critical for species like Vannamei Shrimp and Tilapia.
● Structural Chassis for Insulation: The corrugated steel walls provide the necessary rigidity to support external insulation jackets (Rockwool or PU foam).
● Thermal Performance: Integrated insulation allows farms to maintain a stable 28C to 30C environment with 30% lower energy consumption in cold climates.
Water quality in RAS depends on rapid solids removal.
● The Vortex Effect: The circular geometry promotes a natural centripetal flow, driving waste toward the center.
● Center Drain Compatibility: Our tanks integrate seamlessly with bottom-center drainage, removing 90% of solids instantly to prevent the accumulation of toxic ammonia and nitrites.

Durability | High (Steel Support) | Medium (UV warping) | High (Permanent) |
Center Enamel’s metallurgical bond provides two levels of protection:
1. Integrated Barrier: The zinc-iron alloy layers are physically part of the steel, meaning the coating cannot flake off into the water.
2. Self-Healing Cathodic Protection: If the panel is scratched, the surrounding zinc acts as a sacrificial anode, protecting the exposed steel and preventing rust spread.
To manage algae and biosecurity, we integrate Aluminum Dome Roofs:
● Algae Control: Blocks excessive sunlight to prevent oxygen-depleting blooms.
● Pathogen Shield: Seals the pond against bird droppings and wind-blown dust.
● Thermal Management: Aluminum's high reflectivity prevents rapid water heat-gain during peak summer.
Q: Are galvanized steel ponds safe for food-grade fish?
A: Yes. The water only contacts a food-safe, non-toxic PVC or TPU liner that meets global safety standards for aquaculture biosecurity.
Q: Can these tanks be used for saltwater shrimp farming?
A: Absolutely. For marine environments, we offer an optional duplex coating (epoxy overcoat) on the galvanized exterior to resist salt-air corrosion.
Q: What foundation is required?
A: These modular tanks can be installed on compacted soil or sand foundations, eliminating the need for expensive, permanent concrete pads.
