1. General introduction to containers
Container is a rectangular cargo container, made of steel, has good load-bearing capacity and is widely used in multimodal transport such as: sea, road, rail, etc. At the same time, it is also used in construction, warehousing and used as a type of mobile housing.
Thanks to its sturdy structure and standardized design, containers not only ensure the safety of goods during transportation but also help optimize the process of loading, unloading, storing and preserving goods more effectively.
High quality containers are containers manufactured according to strict international standards such as ISO 668, ISO 11671, ISO 1496 to ensure uniformity and safe load-bearing capacity during transportation, stacking or use for different purposes.
In terms of basic structure, a container consists of six sides forming a closed box: a load-bearing steel frame, bottom and floor, roof panels, longitudinal walls, front, back and doors, and standard assembly angles to facilitate lifting, assembling and transporting the container.
Containers are popular not only for their durability and environmental resistance, but also for their versatility in application – from international freight transport to modern construction solutions such as mobile offices, prefabricated housing and temporary storage.
2. International standards applicable to containers
Containers are manufactured and widely used around the world thanks to their compliance with strict international standards. The application of these standards not only ensures quality and safety but also makes containers easily compatible with transportation, loading and unloading and storage systems in many different countries.
Common international standards for containers include:
-
ISO 668: Regulations on standard dimensions, capacity and load of containers. Thanks to this standard, containers can be stacked, transported and assembled synchronously on ships, trucks, trains without any problems regarding size or load.
-
ISO 1161: Detailed definition of corner fittings/corner castings – important parts that help containers to be lifted, stacked and secured safely during transportation.
-
ISO 1496: Provides technical requirements for construction, materials, load capacity, water tightness, durability and necessary tests to ensure containers meet harsh working conditions.
-
ISO 6346: Standards for container identification codes and symbols, helping to easily manage, trace and control containers globally.
-
CSC (Convention for Safe Containers): International Convention on Container Safety, which specifies requirements for inspection, maintenance and certification of containers before they are put into use.
Benefits of containers that comply with international standards:
-
Ensure absolute safety for goods and people during transportation and unloading.
-
Increased longevity, durability and resistance to weather, impact and corrosion.
-
Easy to maintain, repair and replace components thanks to high synchronization.
-
Supports optimization of transportation and storage costs thanks to flexible stacking and interchangeability.
Compliance with international standards is a must for container manufacturing and supplying businesses, and at the same time brings maximum peace of mind to customers when choosing and using the product.
3. Overall structure of the container
The container has a closed rectangular design, mainly made of high-quality steel to ensure load-bearing capacity, impact resistance and optimal protection of goods during transportation and storage. The overall structure of the container strictly complies with international standards, helping the product to be uniform in size, durability and diverse in use.
The main parts of a container include:
- Container frame (Frame): This is the main load-bearing part, including corner posts, longitudinal beams, cross beams and bottom beams. The container frame creates stability for the entire structure, helping the container withstand large loads and impact forces when loading and unloading or stacking many floors. The structure includes: 4 corner posts, 2 bottom side rails, 2 top side rails, 2 bottom cross members, 1 front top end rail, 1 rear top cross member (door header). The role is to bear the main load, ensuring stability when stacking containers.
-
Bottom & Floor:
The bottom of the container is made up of a system of steel cross beams and longitudinal beams, tightly connected to the frame. The floor is usually made of treated hardwood or steel, ensuring heavy load bearing, anti-warping and termite resistance.
-
Roof Panel:
The roof is usually made of steel or aluminum alloy, flat or wavy design to increase load-bearing capacity and prevent water stagnation, protecting goods from weather effects.
-
Side Wall:
The two sides of the container are made of steel or aluminum, which can be flat or corrugated to increase stiffness, prevent dents and protect goods from external impacts.
-
Front End Wall:
It is a sealing plate at the top of the container, with a similar structure to a longitudinal wall, helping to increase stability and protect goods. -
Rear End Wall & Door:
Behind the container is a sturdy steel double-wing door system, equipped with waterproof rubber gaskets, safety locks and accessories for convenient opening and closing, ensuring that goods are not water-permeable or lost during transportation.
-
Corner Fittings/Castings:
Firmly welded at the four upper and lower corners of the container, these mounting corners comply with ISO 1161 standards, serving as connection points for lifting, stacking and securing containers with specialized equipment.
4. Conclusion
Containers are the optimal solution for modern transportation, storage and construction needs thanks to their solid, synchronous structure and strict compliance with international standards. Every component in the container structure – from the load-bearing steel frame, floor, roof, longitudinal walls to the door system and assembled corners – is designed to ensure durability, load-bearing capacity, impact resistance and maximum protection of goods in all conditions of use.
