20ft HC Shipping Container with Rollup Door – Extra Height, Secure & Easy Access
This 20-foot high cube shipping container offers a secure and weather-resistant storage or transport solution for commercial, industrial, and agricultural applications. The unit features an additional one foot of vertical space compared to a standard container and is fitted with a rear rollup door for convenient ground-level access. Constructed from weathering-resistant COR-TEN steel, this container is designed to withstand harsh elements while protecting its contents. It is suitable for use as onsite storage, a mobile workshop, or for the secure shipment of goods .
Key Features

High Cube Design: Provides approximately one foot of additional interior height (9’6″ externally) compared to a standard 20ft shipping container, allowing for taller equipment or additional shelving.

Rollup Door for Easy Access: Fitted with a rear rollup door that operates on spring-assisted tracks, allowing for full-width access and easier loading and unloading of palletized or bulky items from ground level.

Durable Weather-Resistant Construction: Manufactured with weathering COR-TEN steel to form a rigid, waterproof structure that resists corrosion and rust development over time.

Secure Locking Mechanism: The container includes welded-on locking hardware on the rollup door to accommodate customer-supplied padlocks, helping to deter unauthorized access and secure inventory or equipment .

Ventilated Design: Passive vents are integrated into the container structure to reduce condensation and promote airflow, helping to protect the interior and contents from moisture buildup.

CSC Plate Compliant: Manufactured in accordance with International Convention for Safe Containers (CSC) requirements, certifying the container as safe for transportation and handling.

Detailed Description
The 20ft High Cube (HC) Shipping Container with Rollup Door is a specialized cargo container designed to bridge the gap between standard secure storage and the need for frequent, easy access. Unlike traditional swing doors that require clearance space to open outward, the corrugated sliding rollup door retracts into a box above the opening, making this unit ideal for locations with limited space or for drive-in access with a forklift or pallet jack.
Built for longevity, the container frame and panels are constructed from heavy-gauge weathering steel, which develops a protective patina over time to resist atmospheric corrosion. This makes the container suitable for long-term outdoor placement in various climates across the United States. The flooring consists of marine-grade plywood treated to withstand heavy point loads from forklifts or stored machinery.
The interior of this high cube unit offers ample vertical clearance, making it easier to store tall machinery, racking systems, or bulkier items that would not fit in a standard container. The combination of the high cube height and the full-width rollup door transforms the unit into a versatile asset for job sites needing a secure yet accessible tool shed, or for warehouse expansion requiring durable, modular storage. All structural components, including the door tracks and bottom rails, are built to ISO standards, ensuring the container remains stackable and transportable if needed.

Package Includes

1 x 20ft High Cube Shipping Container with integrated Rollup Door

Unit is sold as a complete, pre-assembled structure. Padlocks, shelving, and interior modifications are not included.

Dimensions and capacity

Internal dimensions are approximately 19 ft 4 in × 7 ft 8 in × 7 ft 10 in (5,898 × 2,350 × 2,393 mm), giving 1,170 cu ft (33.1 m³) of usable space, with double doors at one end. These are the standard figures for a 20ft container; exact internals vary slightly by manufacturer.

Condition

This is a used container that has been in service. It is wind and watertight — no holes, working door seals, an intact roof — but it shows its history: surface rust, dents and previous owner markings are normal and do not affect how it performs.

What it is good for

This unit is commonly used for general cargo and secure storage. Doors, windows, insulation, electrics and paint can all be added before it ships — it is cheaper and neater to specify a conversion while the container is still in our yard than to modify it on your site afterwards.

Standards and inspection

Containers intended for international shipping carry a valid safety approval plate under the Convention for Safe Containers, administered by the International Maritime Organization. Condition grades such as cargo-worthy follow the inspection criteria published by the Institute of International Container Lessors. If you need a unit for shipping rather than static storage, tell us and we will confirm its plate before dispatch.

Delivery

Delivery is quoted against your site access rather than published as a flat rate, because haulage for a container depends on the distance, the approach and whether a crane is needed. Most deliveries use a tilt-bed truck, which needs a clear and reasonably level run about twice the container length. We price it before you commit.
