20ft Used High Cube Shipping Container — Grade A, Wind & Watertight (Used)

Description

The 20ft Used High Cube Shipping Container from Atlas Container Supply is a heavy-duty, wind- and watertight steel unit engineered for secure, long-lasting performance.

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.

• General high-volume storage

Construction & Durability

Every panel on this 20ft steel shipping container is cargo-worthy steel graded wind- and watertight, formed into corrugations that carry load across the wall rather than through it. That is why a container this size can be stacked several high fully laden and still open cleanly on a level pad. The high-cube profile adds a foot of interior headroom over a standard-height unit, which matters for racking, tall pallets, and any fit-out with a ceiling.

Delivery & Site Preparation

Your 20ft steel shipping container arrives on a tilt-bed and is placed directly on your prepared pad. Allow about 75ft of clear, straight approach so the bed can tilt and slide the unit off. Overhead clearance is the detail people forget: branches and low lines will stop a tilt delivery cold, so check the approach as well as the pad.

Why Buy From Atlas Container Supply

Buying used means honest cosmetics — surface scrapes and the odd dent — on a unit that is still certified wind- and watertight. That grading is the whole point: it tells you what you are paying for. Cross-shop 20ft Containers, or start with the buyers guide if this is your first container.
