Product Advantages

Compact High Cube Dry Cargo Design

The 20'HC Dry Cargo Shipping Container combines a compact 20-foot container format with a high cube configuration, providing additional vertical cargo space while maintaining a relatively small overall footprint.

The container is 9'6" / 2.9 m high, featuring a high cube configuration.

This configuration is suitable for dry cargo applications where additional internal height is beneficial but a 40-foot container is not required.

High Payload Capacity

The 20'HC Dry Cargo Shipping Container has the following weight and capacity specifications:

● Maximum Gross Weight: 30,480 kg / 67,200 lb

● Tare Weight: 2,340 kg / 5,160 lb

● Payload / Net Weight: 28,140 kg / 62,040 lb

● Cubic Capacity: 37.5 m³ / 1,322 cu.ft.

These are the product-specific weight and capacity values for this container rather than generic container specifications.

Final cargo loading should always comply with the approved container documentation and applicable transportation requirements.

Enclosed Structure for General Dry Cargo

The fully enclosed steel body is designed for transporting general dry cargo that does not require temperature-controlled equipment.

The conventional rear-door configuration provides a practical solution for standard cargo loading, unloading and containerized transportation.

Stable Steel Structure

The container is manufactured using precision CNC cutting and standardized welding processes, helping maintain structural stability and production consistency.

The corrugated steel body, frame and door structure form a conventional enclosed dry cargo container suitable for repeated logistics use.

Anti-Corrosion Coating System

Before painting, the steel structure undergoes Sa2.5 abrasive blast cleaning.

The coating system includes:

● Zinc-rich epoxy primer

● Epoxy intermediate coat

● Acrylic top coat

Paint thickness and coating adhesion are also inspected during production.

This coating system helps protect the container steel structure against corrosion associated with outdoor storage, port environments and transportation.

ISO Shipping Container Configuration

The 20'HC container follows ISO 1496-1 requirements and undergoes third-party professional testing, with applicable certification documents and test reports available.

Application

The 20'HC Dry Cargo Shipping Container is primarily intended for general dry cargo transportation and multimodal logistics.

General Dry Cargo

The enclosed container body is suitable for a wide range of non-temperature-controlled cargo, including:

● Cartoned goods

● Palletized goods

● Packaged industrial products

● Consumer products

● General manufactured goods

● Other suitable dry cargo

The final cargo type, weight and loading arrangement should remain within the approved container specification.

Cargo Requiring Additional Height

Compared with a standard-height 20-foot container, the high cube configuration provides additional vertical space.

This makes the 20'HC suitable for cargo where height or cubic capacity is important but the additional length of a 40-foot container is unnecessary.

Palletized and Packaged Cargo

The enclosed rectangular cargo space can be used for palletized and packaged products handled through conventional container doors.

Cargo arrangement should be planned according to:

● Pallet dimensions

● Total cargo weight

● Floor loading

● Cargo securing requirements

Industrial Products

Packaged components, manufactured products and other suitable industrial cargo can be transported where their dimensions and weights comply with the approved container limits.

Multimodal Logistics

Standard ocean containers are suitable for multimodal logistics shipments across global ports.

The container can therefore be used within compatible sea, rail and road logistics systems, subject to carrier, terminal and route requirements.
