Most plastic tank “problems” are not material problems — they're geometry and spec problems. Round tanks waste space in square footprints. Rectangular geometry engineered to cut freight costs by up to 80% versus comparable cylindrical tanks, while maximizing volume inside standard containers, trailers, frac tanks, and tight mechanical rooms.
- Fits 20' & 40' Shipping Containers
- Extrusion-Wound HDPE & PP — No External Cages
- Field-Repairable, Field-Weldable Designs
- 110% Double-Wall “Tank-in-a-Tank” Containment
Frequently Asked Questions
Why choose a rectangular tank instead of a cylindrical tank?
Rectangular geometry fits where cylinders can't — inside shipping containers, frac tanks, and tight plants — while maximizing volume utilization and cutting freight costs by up to 80% versus comparable cylindrical tanks.
What's the maximum capacity for a rectangular tank?
Typically up to 18,000 gallons in a rectangular footprint, engineered with extrusion-wound walls that don't bulge under repeated fill-and-drain cycles.
Do rectangular tanks fit standard shipping containers?
Yes — rectangular tanks are commonly engineered to fit inside 20' and 40' shipping containers, a key advantage for facilities needing containerized or mobile chemical storage.
