Product Advantages

Standard 40'GP Dry Cargo Configuration

The 40'GP ISO Dry Cargo Shipping Container is a standard-height 40-foot enclosed freight container designed for general dry cargo transportation.

Unlike a 40'HC high cube container, this model uses the standard 8'6" / 2591 mm external height, making it suitable for conventional dry cargo applications where additional high-cube height is not required. It is classified under our Standard ISO Shipping Containers line.

Verified Cargo Capacity

Standard engineering specifications include:

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

● Tare Weight: 3,740 kg / 8,245 lb

● Maximum Cargo Weight: 26,740 kg / 58,955 lb

● Cubic Capacity: 67.8 m³ / 2,394 cu.ft.

These ratings reflect our strict structural standards for dependable heavy-duty transport.

Enclosed Structure for General Dry Cargo

The fixed roof, enclosed corrugated steel body, and conventional cargo doors provide a practical configuration for non-temperature-controlled freight.

The container is suitable for packaged cargo that requires an enclosed transport space during road, rail, and sea logistics.

Stable Steel Construction

The container is manufactured using precision CNC cutting and standardized welding processes to maintain structural stability and manufacturing consistency.

The main frame, corrugated panels, and other structural components are fabricated according to approved container designs and production requirements.

Anti-Corrosion Coating System

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

The specified heavy-duty coating system consists of:

● Zinc-rich epoxy primer

● Epoxy intermediate coat

● Acrylic top coat

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

This treatment provides robust protection for the steel structure against corrosion associated with outdoor storage, port environments, and marine transportation.

ISO Shipping Container Design

This product complies fully with ISO 1496-1 requirements and undergoes comprehensive testing, with full certification documentation and test reports provided.

Application

The 40'GP ISO Dry Cargo Shipping Container is primarily designed for general dry cargo transportation within multimodal logistics systems.

Cargo dimensions, total weight, and securing arrangements remain strictly within approved container specifications.

Palletized and Packaged Goods

With an internal length of approximately 12,031 mm and an internal width of approximately 2,352 mm, the container provides a long enclosed cargo space suitable for palletized and packaged freight.

The loading plan is optimized around:

● Pallet dimensions

● Cargo weight

● Weight distribution

● Floor loading

● Cargo securing requirements

Industrial Products and Components

Packaged machinery components, manufactured products, and other industrial goods can be transported efficiently within the approved maximum cargo weight limit of 26,740 kg.

High-Volume General Freight

The cubic capacity of 67.8 m³ / 2,394 cu.ft. provides substantial enclosed space for shipments where volumetric efficiency is a critical factor.
