20' Tank Container (T11)
A cylindrical stainless-steel pressure vessel mounted in a standard 20' ISO frame — for bulk liquid chemicals, foodstuffs and other non-hazardous or hazardous liquid cargo. Frame envelope and corner-casting positions match the standard 20' box, so Twistlock Africa's standard-range hardware still applies at the corners; the barrel itself is not a Twistlock Africa product.

Standard: ISO 1496-3 (tank containers); UN Portable Tank / IMDG / RID-ADR approvals; CSC. Source: Eurotainer and Seaco Global T11 standard tank container datasheets (two independent tank-container lessors, figures cross-checked and consistent). Covers the general-purpose chemical/food-grade T11 type only — pressurised gas tank containers (T50 series) are built to a different pressure rating with materially different tare/gross figures and are not represented here. Always confirm the specific unit's CSC plate and T-code before use.
