The Open Top Plastic Tanks catalog at OneSource Plastics includes every active manufacturer SKU across Norwesco, Snyder Industries, Chem-Tainer, Enduraplas, and Bushman — rotomolded polyethylene tanks. Certifications such as ASTM D1998 construction and FDA 21 CFR 177.1520 food-contact resin compliance vary by model and manufacturer, so check each product's Specifications for what applies to that tank. Use the sort and filter controls below to narrow by capacity, brand, or dimensions.
Applications
Water storage — potable, irrigation, fire suppression, livestock
Industrial process holding, batch mixing, and dosing
Agricultural — fertilizer, herbicide, water hauling, livestock watering
Compliance & Standards
All polyethylene tanks in this category are rotomolded from FDA 21 CFR 177.1520 compliant resin and manufactured to ASTM D1998 specification for upright polyethylene storage. UV stabilizers are co-extruded into the resin for outdoor installation. Maximum operating temperature 120°F for HDPE; higher for XLPE (cross-linked polyethylene). NSF 61 certified models available on request for potable drinking water applications — call to specify.
Freight & Delivery
Tanks ship LTL motor freight from the closest stocking warehouse to your delivery ZIP. Typical transit 5-10 business days. Liftgate available at delivery (per-shipment fee). Always inspect at delivery and note any damage on the bill of lading before signing — that is the LTL carrier claim trigger. Bulk-order consolidation reduces per-tank freight 25-40%. Same-business-day quotes: call 866-418-1777 with MPN, quantity, and delivery ZIP.
Sizing & Selection
Pick capacity first, then verify dimensions against your installation footprint. Most rotomolded tanks are built to OEM standard dimensions ± standard rotational-molding tolerance of ±2-3%. Vertical tanks need flat-pad foundation; horizontal/leg tanks need stand or cradle (check listing — some are sold with integrated stand, others require separate stand or band purchase). Application engineering: call 866-418-1777 for sizing, layout, and accessory recommendations.
