Round GRP Tanks for Recirculating Aquaculture Systems (RAS)

Round GRP Tanks for Recirculating Aquaculture Systems (RAS)

Our round GRP (Glass Reinforced Polyester) aquaculture tanks are engineered specifically for Recirculating Aquaculture Systems (RAS) used in modern fish farming and hatchery operations. Built for long service life, hygiene, and operational efficiency, these tanks support sustainable, high-density aquaculture production with minimal maintenance.

Designed for commercial aquaculture facilities, RAS farms, research centers, and hatcheries, our GRP tanks deliver reliable performance in demanding environments.

Smooth, Hygienic Interior Surface Safe for Aquatic Life

Both the interior and exterior surfaces of our GRP tanks are finished with a high-quality gelcoat that is fully safe for aquatic life and optimized for aquaculture use.

Key surface benefits include:

• Smooth, glossy interior that prevents waste buildup

• Easy cleaning and disinfection, reducing labor and downtime

• Optional anti-bacterial gelcoat for enhanced biosecurity

• Long-term chemical and biological resistance

• Non-porous surface that supports healthy fish growth and water quality

This hygienic finish makes our tanks ideal for RAS systems, broodstock tanks, grow-out tanks, and nursery applications.

Heavy-Duty, Modular Support Structure

Our GRP tanks are designed to handle high water loads and continuous operation. Depending on your project requirements, tank support systems can be customized for strength and flexibility.

Support structure options include:

• Integrated or separate support legs

• Support legs manufactured from galvanized steel or fiberglass

• Custom leg heights to match site conditions and piping layouts

For additional reinforcement, we offer external galvanized steel or plastic pipe rings, fully coated with polyester and gelcoat. This creates a single, corrosion-resistant structure that improves durability and extends service life in wet and harsh environments.

Custom Sizes, Volumes, and Design Options

Because we manufacture our own composite molds, we are not limited to standard dimensions. We provide fully customizable GRP aquaculture tanks tailored to your RAS design and production goals.

Customization options include:

• Multiple diameters, depths, and volume capacities

• Custom gelcoat colors and surface finishes

• Tank designs compatible with bottom drains, side outlets, overflows, and sensors

• Manufacturing adapted to project-specific technical connections

Whether you need a single tank or a complete RAS tank package, we deliver solutions that integrate seamlessly into your system.
