NZ Made Fibreglass Tanks

Custom Fibreglass Tanks for Every Industry

At Richmond Fibreglass, we design and manufacture high-quality tanks for aquaculture, research, aquaponics, water storage, and septic applications. Our tanks are proven and trusted across these sectors throughout New Zealand.

We offer both one-off moulds and full-production moulds, built to handle everything from unique prototypes to large-scale production runs. We can add fittings and other add-ons to your exact requirements.

A gel coat surface is ideal for most tanks because it offers a combination of durability, hygiene, and ease of maintenance—all critical for many tank environments.

Here’s why it stands out:

• Smooth, non-porous finish: Gel coat creates a slick surface that resists buildup of debris and makes cleaning much easier, which is essential for maintaining chemical quality, water quality and fish health.
• Corrosion and chemical resistance: It holds up well against chemicals, saltwater, disinfectants, and other harsh substances. 
• UV protection: Gel coat helps shield tanks from sun damage, extending their lifespan—especially important for outdoor installations.
• Long-lasting appearance: It maintains a glossy, professional look over time, even with heavy use.
• Customisation: Gel coat can be tinted to improve visibility inside the tank, provide an ideal environment for growing fish and/or match branding and it can be tailored for specific resistance needs.

In short, gel coat doesn’t just make tanks look good—it helps them perform better, last longer, and stay cleaner with less effort.

We use advanced manufacturing techniques and uphold strict quality control standards, ensuring every product meets your performance and budget goals—on time, every time.
