Product Advantages

Full Side Opening for Easier Cargo Access

The 40'HC Full Side Opening Container is designed with an extended opening along the side of the container, providing significantly more lateral access than a conventional dry cargo container that relies mainly on end-door loading.

The side-opening arrangement is particularly useful when cargo dimensions, shape or handling procedures make loading through standard end doors inconvenient.

It provides greater flexibility for loading and unloading:

● Large industrial equipment

● Bulky cargo

● Wide components

● Irregularly shaped cargo

● Cargo requiring access from the side

The actual loading method should be determined according to cargo dimensions, weight and handling requirements.

Side Vertical Middle Post Structure

A vertical middle post is incorporated into the opening side as part of the container's structural configuration.

This central structural member helps maintain the integrity of the side-opening arrangement while allowing extensive access to the cargo space from the side.

Because the exact middle-post and door configuration may vary according to the approved design, details such as the opening arrangement and operating method should be confirmed from the final technical drawing.

40'HC High Cube Configuration

The 40'HC configuration provides the additional vertical space associated with a high cube container while retaining the advantages of full-side cargo access.

This combination is useful for cargo that requires both:

● Greater internal height

● Wider side access during loading and unloading

The exact dimensions and loading parameters should be confirmed according to the approved product specification.

High-Strength Steel Construction

The container is manufactured using a high-strength steel structure with precision CNC cutting and standardized welding processes.

The frame, wall structures and side-opening components are fabricated according to the approved container design to maintain structural stability during handling, transportation and repeated use.

Anti-Corrosion Coating System

The steel surface undergoes Sa2.5 abrasive blasting before application of the specified protective coating system.

The coating configuration includes:

● Zinc-rich epoxy primer

● Epoxy intermediate coat

● Acrylic top coat

Paint thickness and coating adhesion are inspected during the coating process.

This surface treatment helps protect the steel structure against corrosion during outdoor storage, marine transportation and normal logistics operations.

Application

The 40'HC Full Side Opening Container is primarily designed for cargo transportation applications where convenient side access can improve loading and unloading efficiency.

Industrial Equipment Transportation

Large machinery and industrial equipment may be difficult to position through conventional container end doors.

The full-side opening provides a wider access area, allowing loading arrangements to be planned around the shape and dimensions of the equipment.

Bulky and Irregular Cargo

The container is suitable for bulky or irregularly shaped cargo where restricted end-door access makes conventional loading inefficient.

Side access provides greater flexibility when positioning cargo inside the container.

Large Components and Project Cargo

Long, wide or large industrial components can benefit from an extended side opening, particularly when multiple access points are required during cargo positioning and securing.

The final suitability depends on cargo dimensions, weight distribution and securing requirements.

Cargo Requiring Frequent Side Access

For logistics operations where cargo needs to be accessed from different positions along the container body, a full-side opening configuration can provide greater operational flexibility than a conventional end-opening dry container.

Multimodal Logistics

As an ISO shipping container product, this container is intended for multimodal logistics applications involving road, rail and sea transportation.

The final transportation arrangement should comply with the approved container specification, CSC requirements where applicable, cargo securing requirements and individual carrier rules.

FAQ

What is a 40'HC Full Side Opening Container?

It is a 40-foot high cube shipping container designed with extensive cargo access along the side of the container rather than relying only on conventional end doors.

This configuration is ideal for cargo that is difficult to load or unload through standard end-door openings.

What is the function of the side vertical middle post?

The vertical middle post forms an essential structural member along the opening side of the container.

It maintains the structural rigidity and load-bearing integrity of the full-side opening configuration while providing wide lateral access to the cargo space.

Is the middle post removable?

Standard configurations include a fixed structural vertical middle post. We can also engineer and manufacture a removable or swing-away middle post upon request to meet specific cargo loading requirements.

What is the advantage of full-side opening compared with a standard dry container?

A conventional dry cargo container is primarily loaded through its end doors.

A full-side opening container provides much broader lateral access, simplifying the handling of long, wide, or irregularly shaped cargo, and enabling direct access to goods positioned at any location along the container body.

What types of cargo are suitable for this container?

Typical applications include:

● Industrial equipment

● Bulky cargo

● Wide components

● Large machinery

● Irregularly shaped cargo

● Project cargo requiring side access

Is this container suitable for multimodal transportation?

Yes. It is fully engineered as an ISO shipping container for multimodal logistics applications across road, rail, and sea networks, compliant with all standard payload and CSC certification requirements.

What standard does the container follow?

The container is designed and manufactured in full accordance with ISO 1496-1 requirements.

Can Boxwell provide a CSC Certificate?

Yes. We supply CSC Certificates and safety approval plates according to project and order specifications.

Is this an offshore container?

No. This model is categorized under ISO Shipping Containers for standard multimodal logistics. It is not an offshore CCU designed for offshore dynamic lifting under DNV-ST-E271 or EN 12079.

Does every container require NDT or offshore lifting tests?

No. As a standard ISO shipping container, it undergoes standard ISO structural and load tests. Specialized non-destructive testing (NDT) or offshore dynamic load testing can be arranged upon request for specific project requirements.

What anti-corrosion treatment is used?

The standard surface treatment includes:

● Sa2.5 abrasive blasting

● Zinc-rich epoxy primer

● Epoxy intermediate coat

● Acrylic top coat

Coating thickness and adhesion are strictly verified during the quality control process.

Can the side-opening configuration be customized?

Yes. We support custom manufacturing based on customer drawings, specific door configurations, locking mechanisms, and dimensional requirements, ensuring the final design satisfies all structural and certification standards.

Are the dimensions and payload the same as every standard 40'HC container?

Because the full-side opening and vertical middle post involve specific structural reinforcements, the exact internal dimensions, tare weight, and payload are defined by the approved engineering drawing and CSC plate for each order.

What information should I provide for a quotation?

To evaluate the appropriate container configuration, please provide:

● Cargo type

● Cargo dimensions

● Cargo weight

● Loading and unloading method

● Required side access

● Required door opening size

● Whether the middle post requires a specific operating arrangement

● Required certification

● Quantity

● Destination

● Customer drawings or technical specifications, if available
