Choose one of our many standard fiberglass rectangular tanks or let us design a custom built fiberglass rectangular tank specifically suited to your needs. For a list of our standard tanks: View Rectangular Tank Sizes and Specifications Fiberglass rectangular tanks may be the best example of the versatility of fiberglass when it comes to custom built liquid containment. We have been building custom rectangular fiberglass tanks since 1986 and have extensive experience in designing high performance tanks for aquaculture and industrial applications. In 2012 Dura-Tech increased our capacity to meet our customers’ needs by investing in 3D modeling software.  We now can produce any size and shape tank model and test it for structural integrity then produce detailed shop drawings for customer approval. This significantly reduces the turnaround time for custom fiberglass tanks. All Dura-Tech fiberglass tanks are durable, and corrosion resistant and 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 virtually last forever. 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. Installation is easy, but if you need help we will provide you with support via our professional on-site services. Options:
  • Closed top or open top.
  • Encapsulated Insulation can be added during the lamination process
  • Fittings / baffles / anti-vortex plates/ mounting brackets are all available
  • Sumps, (standard and double drain)
  • Stand pipes (internal and external)
  • A wide variety of interior and exterior gelcoat colours are available
  • Flat bottom or sloped available on most models
  • Support stands or skirts
