Rectangular Tanks

Dura-Tech rectangular fiberglass tanks are built for aquaculture and industrial applications where efficient use of space, custom dimensions, and reliable containment are required. Rectangular tanks are a practical choice when a facility needs to fit tank capacity into a defined room, rack, raceway, processing area, or equipment layout.

Dura-Tech has been building custom rectangular fiberglass tanks since 1986. Standard models are available, and custom tanks can be designed for your specific footprint, volume, flow, fittings, access, and structural needs. Dura-Tech uses 3D modeling software to support tank design, structural review, and shop drawings for customer approval.

Fiberglass construction gives rectangular tanks a strong combination of durability, corrosion resistance, low maintenance, and clean interior surfaces. Tanks can be built open or closed top, insulated, fitted with baffles, sumps, standpipes, anti-vortex plates, mounting brackets, support skirts, or custom fittings.
