Dura-Tech fiberglass tanks are durable, lightweight and rustproof. We have been building fiberglass rearing and grow out tanks for the aquaculture industry since 1986. We have a large inventory of tank models to suit all types of hatchery and grow out tank requirements. Although we can build virtually any size tank our standard sizes range from 11 US gallons up to and including our largest standard size tank of over 86,000 US gallons.

All of our standard fiberglass tanks are built ready to use with an isopthalic gelcoat providing an easily cleaned interior surface. There is no struggling with liners, unlike steel tanks fiberglass is rustproof and if properly maintained, can last forever. The versatility of fiberglass construction allows us to completely encapsulate insulation or add extra strength in areas where fittings or side pods will be mounted during the laminating process.

Transporting and installation of our fiberglass tanks could not be easier. We work closely with our trucking partners to design loads that maximize efficiency of space to provide the best delivery value to our customers. We offer professional on-site installation of all of our fiberglass tanks.

We can provide cost-effective transportation to your site anywhere in North America. We work closely with our trucking partners to design loads that maximize efficiency of space and provide the best delivery value.

Installation is easy, but if you need help we will provide you with support via our professional on-site services.
