Product Details

Inspect the industrial-grade materials and precision manufacturing that define a Bancy tank.

Corrosion-Resistant Galvanized Sheets

Built to last 10+ years. We use hot-dip galvanized corrugated steel sheets that withstand humid environments and saltwater corrosion better than standard metal tanks. The corrugated design adds structural integrity, preventing deformation under high water pressure.

Corrugated hot-dip galvanized steel sheet for aquaculture tanks, offering superior corrosion resistance for saltwater environments.
High-quality welded PVC fish tank liner seam ensuring a smooth and flat surface safe for sensitive fish skin.

Fish-Safe Smooth Seams

The heart of the tank. Our liners utilize High-Frequency Welding to ensure smooth, flat seams that won’t injure fish skin.

Modular Bolt Assembly

Reduce your construction costs significantly. The modular bolt-together design allows for rapid assembly by a team of 2-3 people without heavy machinery. Perfect for remote farm locations.

Frequently Asked
Questions

Answers to common queries regarding installation and materials.

Can this galvanized steel fish tank be used for saltwater?

Yes. The galvanized coating provides basic rust protection, and the high-grade PVC liner completely isolates the water from the steel wall, making it safe for saltwater environments like shrimp or eel farming.

To ensure cost-efficiency and fast delivery, we provide standardized assembly schematics and manuals. These are sufficient for installation.

PVC is cost-effective and suitable for most freshwater projects. TPU is a premium option that is food-grade, more resistant to abrasion and oil, and remains flexible in extreme cold temperatures.
