This 20ft used high cube shipping container is a Grade A used ex-shipping-line unit in Wind and Watertight (WWT) condition, fully inspected and confirmed to be in excellent structural and weatherproofing condition before dispatch. Grade A is a supplier-grade designation indicating a higher-quality selection within the used WWT category — units graded at this level are chosen for minimal denting, better surface condition, and consistent door and seal performance compared to standard WWT stock. The unit does not carry a valid CSC plate and is intended for on-site storage use rather than active international freight.

The high cube configuration provides an external height of 9ft 6in (2,896mm) and an internal height of 8ft 10in (2,698mm) — one full foot taller than a standard 20ft container — giving a cubic capacity of approximately 1,320 cu ft. This additional headroom is suited to tall racking, large equipment, stacked goods, and conversion projects where internal lining or insulation will reduce finished clearance. The taller door opening height of 8ft 6in (2,591mm) also provides greater vertical clearance for loading tall items through the end doors compared to a standard 8ft 6in external height container.

Access is via exterior double hinged cargo doors at one end, each fitted with two heavy-duty locking bars for secure closure. Four vents provide passive airflow to manage condensation. Forklift pockets are fitted on both sides for straightforward site repositioning. The floor is 28mm marine-grade plywood on steel cross-members. The frame, cladding, and corner castings are COR-TEN weathering steel throughout.

For guidance on container siting and permit requirements in the USA, refer to the International Code Council building standards reference.
