Containers are a fundamental part of goods transportation.
Due to their airtight and robust structure, they are the most effective solution to protect cargo from weather conditions, as well as potential impacts or theft, ensuring it arrives in optimal condition at its destination. They allow goods to be transported safely, efficiently, and economically by sea, land, and rail.

Regulated by international standards, they ensure a smooth and secure logistics chain worldwide. The use and manufacture of shipping containers are governed by the International Convention for Safe Containers (CSC), which defines the necessary tests and certifications for approval under ISO standards. All containers used in international transport must bear the CSC plate, confirming their compliance.

Our containers are manufactured with a higher number of ventilation grilles (air vents) than standard market models: 14 vents in 20-foot containers and 20 vents in 40-foot containers. This improvement increases internal air circulation, helping to reduce condensation during transportation and storage. This is particularly beneficial in humid environments or when storing moisture-sensitive products.

In this article, we review the most commonly used types of shipping containers, their technical features, and main applications.

Standard 20′ container

It is the most common container for general cargo. Our 20’ units are manufactured with the EOD (Easy Open Door) system.
The difference between a standard 20’ container and a 20’ EOD lies in the door opening and closing mechanism. Its easy opening and closing make it ideal for frequent use.
A standard 20’ container has 4 locking bars—2 on each door leaf—to ensure a hermetic seal, while a 20’ EOD has 2 bars on one leaf and 1 bar on the other.
Both systems guarantee airtightness, and both containers are CSC certified.

Standard 40′ container

This model is widely used for high-volume cargo. Its capacity and dimensions make it an ideal choice for transporting general goods in international operations.
Our 40’ containers are manufactured to the highest quality standards, with a corten steel structure and bamboo wood flooring, ensuring strength, durability, and a completely airtight seal.
Most are built, like the 20’ models, with the EOD (Easy Open Door) system, whose simplified locking mechanism facilitates easy door opening and closing.
The standard 40’ model typically features 4 locking bars (2 per door leaf) to ensure a watertight seal, while the EOD version includes 2 bars on one leaf and 1 on the other, making handling easier without compromising airtightness.
Both versions comply with international CSC regulations and are ready for intermodal transport.

High Cube containers (HC)

It features extra height. Both the 20’ High Cube and 40’ High Cube containers reach 9’6”, equivalent to 2.89 meters. This provides approximately 13% more capacity, making them suitable for higher-volume loads.

This feature makes them ideal for light but bulky goods, or when additional height is required for handling, ventilation, or insulation. Like the other models, most of our High Cube containers are built with the EOD (Easy Open Door) system, which makes them easier to open and close during frequent use, such as in storage or daily loading/unloading.

Double Door containers (DD)

There are 20’ containers with double doors that allow independent access from each end.

The 20’ Double Door shipping container features two access points, allowing both ends of the container to be opened for much more flexible and convenient operation. This feature makes it especially practical for sectors such as self-storage, urban logistics, or modular transformation projects.

The double access makes it possible to divide the container internally into two independent spaces of approximately 3 usable meters each, doubling its functionality and making it ideal for use as mini storage units, rental spaces, or separate compartments for different types of cargo. In addition, we also manufacture them with the EOD (Easy Open Door) system.

High Cube Double Door containers (HCDD)

The High Cube Double Door models combine two of the most in-demand features: the extra height of High Cube units and the dual access of Double Door containers. With an external height of 2.896 meters and doors at both ends, they offer a highly functional solution for operations requiring increased capacity and operational flexibility. We offer the 20’HCDD and 40’HCDD models.

They are especially useful in storage, transformation, or logistics projects that require independent access or frequent handling from both sides of the container. They are particularly recommended for bulky goods, palletized products, or logistics needs that require access from both ends. They are also used in modular installations, mobile storage units, and compartmentalized spaces.

Manufactured with corten steel and bamboo flooring, and available with the EOD (Easy Open Door) system, they guarantee durability, ease of use, and watertightness.

Open Side Containers (OS)

The 20’ Open Side shipping container (ISO 22 GD) features an additional side access, consisting of multi-leaf sliding doors along one side, in addition to the container’s standard double rear doors. This design allows one entire side to be opened, enabling full access to the interior.

This feature makes it a highly practical solution for loading long, bulky, or difficult-to-handle goods, as well as for logistics operations that require frequent access to the contents without needing to unload everything.

The Open Side model is also widely used in transformation projects (such as stands, offices, or industrial equipment) and as a construction site warehouse or mobile workshop, thanks to its versatility and ease of customization.

Other versions of this model include the 20’ container with doors on both sides or the 40’ High Cube Open Side version.
