1600 Gallon 30 Degree Cone Bottom Tank with Poly Stand: Complete Buyer's Guide
A 1,600-gallon 30-degree cone-bottom tank from Norwesco shipped with its poly stand for turnkey self-draining mixing, in 1.5-specific-gravity polyethylene.
Specifications at a Glance
Every figure below is pulled straight from the live product record for this exact tank — the same data on the product page, so what you read here and what you buy never disagree.
Standards & Materials
- ASTM D1998 — Standard Specification for Polyethylene Upright Storage Tanks. Governs wall-thickness and hydrostatic design for vertical rotomolded poly tanks of this class.
- FDA 21 CFR 177.1520 — Olefin polymers. The food-contact regulation the FDA-grade resin in this tank is compounded to meet.
- Specific gravity rating 1.5 — the tank is engineered for liquids up to 1.5× the density of water (water is about 8.34 lb/gal). Confirm your fluid’s SG before storage.
Product Overview
The 1,600-gallon 30-degree cone-bottom tank arrives complete with its poly stand, a turnkey self-draining vessel for serious mixing and batch processing. The 30-degree cone is steep enough to clear most slurries and settled solids to the center outlet, and bundling the matching stand means you are not sourcing or matching support separately. Standing 96 inches tall on an 89-inch diameter, the combined tank and stand weigh 524 pounds.
The seamless one-piece rotomolding of virgin linear polyethylene is rated to 1.5 specific gravity — dense liquids up to 12.5 pounds per gallon. Through the translucent white walls you read the level by eye; they reflect sun to keep contents cooler, and the resin is FDA-compliant for food-grade liquids.
The included poly stand carries the full load — about 20,540 pounds at the rated gravity — through its legs and the tank's flange, never on the cone apex. At the cone tip, a factory-installed 2-inch outlet is leak-tested for clean draw; the 16-inch lid opens the top. Norwesco's 3-year warranty applies.

Installation and Setup Guide
The matching poly stand in the box simplifies setup, but ten tons of liquid still demand a level pad and an assembled stand that shares its load evenly. The cone apex carries nothing.
Site Preparation and the Stand
Assemble the included poly stand per instructions and set it on a four-inch compacted gravel pad or a concrete slab, finished flat so all legs share the 20,540-pound load. The stand is engineered for this tank; do not substitute an undersized one or rest the cone on the ground. Anchor as specified and add containment where the chemistry warrants it.
Placement and Connections
The stand raises the cone outlet enough for a full-port valve and a drain line beneath. Pipe the 2-inch center outlet down through a brief, chemical-rated flexible link to preserve the complete-drain advantage at the discharge, choosing valve and seals to suit the chemistry.
Venting
Vent generously through the lid so the tank breathes on fill and drain, and fit a chemistry-rated relief vent for off-gassing contents.
Maintenance and Long-Term Care
Keep the included stand on the inspection list — its legs carry the full ten tons.
Quarterly Inspection Checklist
- Poly stand: check legs and joints for cracks, loosening, or settling, and confirm even leg loading.
- Cone and shell: inspect the 30-degree cone and the cone-to-sidewall transition for stress whitening or bulging.
- Outlet and seals: look the center valve and gaskets over for chemical attack, check that it actuates freely, and never wrench the poly threads.
- Vent: verify the lid vent is clear.
Cleaning and Chemical Changeover
The 30-degree cone drains complete, so changeovers rinse clean without a residual heel. Run the manufacturer's decontamination protocol, capture and dispose of the rinsate by label and regulation, and confirm the new chemical suits the polyethylene and seals before refilling.
UV and Weather Protection
Some light passes through the white wall; shield light-sensitive or algae-prone contents from strong sun and check the wall annually.
Alternatives and Comparisons
This 1,600 ships stand-included with a 30-degree cone — the all-purpose self-draining angle. The same tank is available without a stand if you have suitable support. A 15-degree cone of similar volume stands lower but leaves a flatter floor; a 45-degree cone clears the heaviest sludges at greater height. For storage without a drainage requirement, the flat-bottom 1,600-class verticals need no stand.

Frequently Asked Questions
How long will the 1600 Gallon 30 Degree Cone Bottom Tank with Poly Stand last?
With compatible chemistry, the included stand maintained and level, and use within its 1.5 SG and 120 F limits, expect 15 to 20 years. The stand's integrity is as decisive as the shell — keep both sound and the seamless tank reaches the long end of that range.
What chemicals can I store in this tank?
Rated for 1.5 specific gravity, it carries agricultural chemicals, fertilizers, slurries, and industrial solutions of that weight, in FDA food-grade resin. Not for fuels, solvents, or flammables. Run your chemical and your elastomers past a compatibility chart before filling.
What kind of foundation does a 1600-gallon tank need?
The included poly stand carries the tank's full 20,540-pound load through its legs and flange, never the cone apex, so the foundation supports the stand. Assemble the stand per instructions and set it on a four-inch compacted gravel pad or a concrete slab, finished flat so all legs share the load, then anchor it as specified. Do not rest the cone on the ground.
Does this tank come with a warranty?
A three-year Norwesco warranty stands behind the build, covering factory molding and fitting defects. Overloading, an inadequate or damaged stand, chemical attack, and impact fall outside coverage. Keep records for any claim.
Can I install this tank underground?
No. Cone-bottom tanks are above-ground, stand-mounted vessels and are never buried. Any below-grade need calls for purpose-engineered underground tanks.
Buying Considerations
With the stand included, the checks simplify: a flat pad for the assembled stand, a chemical at or under 1.5 SG compatible with the polyethylene and seals, and a freight plan — this tank-and-stand ships LTL by flatbed and needs a forklift to unload. Let us know your site access and we will set up the delivery.
