The Chem-Tainer 360 Gallon PP Cylindrical Open Top Tank (SKU TC4848AB) is a natural white polypropylene open top tank built for straightforward, gravity-fed water storage, process staging, and batch work where you need full top access. At 48 inches in diameter and 48 inches tall, it holds a nominal 360 gallons and sits on a clean 48.0 x 48.0-inch footprint, so you can lay out your pad or platform around a four-foot square.
Will this open top tank work for your setup?
This is a cylindrical open top tank: the top is fully open for manual filling, mixing, dipping, and batch handling rather than sealed or pressure service. It is a bare vessel — no pre-installed bulkhead fittings, drain outlet, or gasketed penetrations ship with this SKU, so any bottom or side connection must be field-added and sealed to suit your plumbing. The polypropylene construction suits water storage and process staging, including warmer service than a standard polyethylene water tank. Size it honestly: at 360 gallons of water this tank carries roughly 3,002 pounds when full, and that loaded weight — not the 360-gallon label — governs your install. Run your capacity against our Tank Sizing Calculator and cross-check the method in the Tank Sizing Guide before you commit.
Foundation and support
A full 48-inch tank drops more than 3,000 pounds onto a small square of ground, so the base must be flat, continuous, and rated for the load. For an above-ground slab install, our guide to concrete pad sizing for above-ground tanks walks through the ACI framework for getting the pad right. Support the full flat bottom across its whole footprint rather than on isolated points, and because the top is open, site the tank where debris, weather, and contamination stay controlled. If this vessel is one stage in a larger holding train, our guide to industrial water-reuse tank topology covers how open and banded storage vessels sequence together.
The mistake to avoid
The most common misstep with an open top tank is treating rated gallonage as the only number that matters. The figure that governs your install is the full-water weight — about 3,002 pounds here — not the 360 on the label. Undersize the pad or the support and you invite settling, stress, and eventual failure. Confirm your foundation carries the loaded weight, and match the tank to your real duty rather than buying on capacity alone.
