    Heavy-Duty Galvanized Steel Stock Tank for Outdoor Use

    You don’t want to keep replacing tanks every few years just because they can’t survive a little sun, salt, or structural load. That’s where YUTANK’s Heavy-Duty Galvanized Steel Stock Tank comes in.

    Built from Q235B structural-grade steel, fully hot-dip galvanized inside and out, this tank is designed to handle extreme RAS aquaculture conditions, high-capacity grow-out operations, and even outdoor rooftop installations in coastal cities. It’s modular, relocatable, and strong enough to support thousands of liters of water without a single weld seam.

    Whether you’re looking to expand your recirculating aquaculture setup or need rugged containment that won’t buckle in the heat — this tank is ready.

    The YUTANK Heavy-Duty Galvanized Steel Tank isn’t just any stock tank. It’s engineered specifically for commercial-scale aquaculture operations that demand long service life, structural integrity, and fast on-site deployment—even under tough conditions.

    🔩 Construction That Holds Up

    Each tank panel is made from Q235B carbon structural steel, laser cut and cold-bent for high load capacity. Then it’s fully hot-dip galvanized (not just electroplated), giving it a zinc layer thickness of 80–120μm that protects against seawater, UV rays, and corrosion in all-weather environments.

    The walls are assembled using pre-drilled flanged panels joined with galvanized bolts and waterproof sealing tape. That means:

    • No on-site welding

    • No expensive coating repairs

    • 100% modular and relocatable

    🛠 Flexible Configurations

    Available in round and rectangular formats, these tanks range from 1.5 meters to 6 meters in diameter, with custom heights from 1m to 2.5m. They can also be tailored with inlet/outlet ports, overflow protection, slope-bottom drainage, or even canvas inner liners for enhanced hygiene in fish fry applications.

    Whether you’re installing on rooftops, indoor farms, coastal outdoor grow-out sites, or mobile testing stations—this tank adapts to your plan.

    🐟 Built for Aquaculture, Not Just Water

    This isn’t a general-purpose metal tank. Every design choice—from the smooth interior for easy cleaning to lift lugs for crane hoisting—is made with RAS farms, hatcheries, and grow-out modules in mind.

    You’re not just getting a tank. You’re getting a scalable infrastructure component that fits seamlessly into professional fish farming systems.

    Here’s the technical breakdown of the Heavy-Duty Galvanized Steel Stock Tank based on verified YUTANK engineering parameters:
