Product Advantages

Soft Open Top Design for Flexible Cargo Loading

The 40'GP Soft Open Top Container features an open roof structure covered by a removable PVC tarpaulin.

Compared with a conventional dry cargo container with a fixed steel roof, the open-top configuration provides direct access from above. This makes loading more convenient for cargo that is difficult to handle through standard container doors.

The PVC tarpaulin provides a flexible roof covering after cargo loading and can be removed when top access is required.

Suitable for Heavy and Oversized Cargo

The open-top structure is particularly suitable for cargo requiring vertical loading by crane or other suitable handling equipment.

Typical cargo can include:

● Heavy machinery

● Industrial equipment

● Tall cargo

● Bulky components

● Cargo that cannot be conveniently loaded through standard container doors

The actual cargo weight, dimensions and securing method should always be confirmed against the approved container specification before shipment.

High-Strength Steel Structure

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

The frame and body are designed to provide structural stability during cargo handling, transportation and repeated use.

Structural details are manufactured according to the applicable container design and approved production requirements.

Anti-Corrosion Surface Protection

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

The coating system includes:

● Zinc-rich epoxy primer

● Epoxy intermediate coat

● Acrylic top coat

Paint thickness and coating adhesion are inspected as part of the coating quality control process.

This surface protection helps improve corrosion resistance during transportation, outdoor storage and marine shipping environments.

ISO Shipping Container Configuration

The container is designed according to ISO 1496-1 requirements applicable to general-purpose freight containers.

Its 40'GP configuration allows it to be used within conventional container logistics systems while providing additional loading flexibility through the soft open roof.

Application

The 40'GP Soft Open Top Container is primarily designed for international cargo transportation where conventional closed-roof containers cannot provide suitable loading access.

Heavy Machinery Transportation

Machinery that is difficult to move through standard container doors can be lowered into the container from above using suitable lifting equipment.

This provides greater flexibility for industrial equipment transportation.

Oversized and Over-Height Cargo

Open top containers are commonly used for cargo whose dimensions or loading requirements make conventional general-purpose containers unsuitable.

Where cargo extends above the normal roof line, the transportation arrangement must be evaluated according to the actual cargo dimensions, route and carrier requirements.

Industrial Equipment and Components

Large industrial components, production equipment and other bulky cargo can be loaded vertically where appropriate.

This is especially useful when cargo shape or handling restrictions prevent conventional horizontal loading.

Multimodal Cargo Transportation

As an ISO shipping container product, the 40'GP Soft Open Top Container is intended for multimodal logistics applications involving container terminals, ports and other conventional freight handling systems.

Actual acceptance for a specific shipment depends on cargo dimensions, weight, securing arrangement and the requirements of the carrier and transportation route.

FAQ

What is a 40'GP Soft Open Top Container?

It is a 40-foot standard-height general-purpose shipping container designed with an open roof structure covered by a removable heavy-duty PVC tarpaulin.

This configuration allows overhead vertical crane loading when handling cargo that is difficult or impossible to load through conventional end doors.

What is the roof cover made of?

This model uses a high-durability, weather-resistant PVC tarpaulin supported by removable steel roof bows.

The tarpaulin and bows can be fully removed during top-loading operations and secured with TIR cords once loading is complete.

What type of cargo is suitable for an open top container?

Open top containers are commonly used for:

● Heavy machinery

● Bulky industrial equipment

● Tall cargo

● Large structural components

● Cargo requiring top loading

Can cargo be loaded by crane?

Yes. The open-top design is engineered specifically for vertical loading and unloading via overhead cranes, mobile cranes, or gantry lifting systems.

Can it carry over-height cargo?

Yes. Open top containers can accommodate cargo that exceeds the standard roof line (Out of Gauge / OOG), subject to carrier stowage approvals, transit route clearance, and specialized lashing requirements.

What standard does the container follow?

The container is designed, fabricated, and tested in strict accordance with ISO 1496-1 requirements for Series 1 freight containers.

Can you provide a CSC certificate?

Yes. Every container is supplied with a valid CSC Certificate and safety approval plate for international multimodal shipping.

What anti-corrosion treatment is used?

Our standard marine surface protection includes:

● Sa2.5 abrasive blasting

● Zinc-rich epoxy primer

● Epoxy intermediate coat

● Acrylic top coat

Paint dry film thickness (DFT) and coating adhesion are strictly inspected and verified during quality control.

Is this an offshore container?

No. This product is categorized under ISO Shipping Containers for standard multimodal logistics.

For offshore energy and marine platform operations requiring DNV-ST-E271 or EN 12079 certification, our offshore CCU container line should be selected.

Does every container include DNV-ST-E271 certification?

No. DNV-ST-E271 applies specifically to offshore containers. Standard ISO open-top containers are supplied with ISO 1496-1 compliance and CSC certification.

Do you provide third-party testing?

Yes. We coordinate third-party professional testing and certification through major classification societies (such as ABS, BV, CCS, DNV, or LR) based on project requirements.
