Steel cargo containers, also known as intermodal containers, are robust, rectangular storage units made primarily from high-strength corrugated steel. These industrial-grade boxes, typically 8 feet wide, 8.5 feet tall, and either 20 or 40 feet long, are designed to be easily transported between different modes of transport – from ship to rail to truck – without needing to unload and reload their cargo. These containers are built to withstand the harsh realities of international shipping. Subjected to rough handling, varying weather conditions, and constant motion, they must be strong enough to protect valuable merchandise throughout its journey across the globe. Because of their durability and water-resistance, steel cargo containers are trusted to carry everything from electronics and appliances to clothing and furniture.
Designed with a standard size and shape, they can be stacked neatly like building blocks on cargo ships, making them the backbone of global trade. In fact, approximately 90% of all shipped goods worldwide are transported in cargo containers. Their uniformity means they can easily fit onto trucks, trains, and ships, and can be handled by standard equipment at ports around the world, promoting efficiency in global logistics.
Production of Steel Containers
The production of steel containers, such as cargo containers, involves a complex and multi-stage process. Here's a breakdown of each step in the production process:
1. Unrolling & Cutting: The process begins with the unrolling of large steel coils. These steel sheets are then cut into the required sizes for the sides, roof, and floor of the container.
2. Surface Treatment: The cut steel sheets undergo surface treatment to remove any impurities and to prepare them for further processing. This can include processes like sandblasting, which cleans and etches the surface.
3. Corrugation: The steel sheets for the sides and sometimes the roof are corrugated. This corrugation process involves shaping the steel sheets into a wave-like pattern, which adds strength and rigidity to the container.
4. Fabrication of Roof Panels: Separate roof panels are fabricated, often using a different process or material to optimize for strength and durability.
5. Fabrication of Floor Braces: Floor braces are fabricated separately. These braces will support the container's floor and provide additional structural integrity.
6. Different Stages of Welding: Various components of the container are welded together. This includes welding the sides to the frame, attaching the roof, and securing the floor braces.
7. Door Frame Assembly: The door frame is assembled separately. It includes the frame, the locking mechanisms, and other components necessary for a functional door.
8. Installation of Doors & Walls onto Floor Frame: The doors and corrugated walls are installed onto the floor frame. This step starts to bring the shape of the container together.
9. Installation of Roof: The roof panel is installed onto the top of the container, completing the basic structure.
10. Priming: The assembled container is primed to protect the steel and prepare it for painting. Priming helps in preventing corrosion.
11. Painting: The container is painted, which adds another layer of corrosion protection and gives the container its final appearance.
12. Installing Floor Panels & Door Hardware: The interior floor panels are installed, and the door hardware, such as locking mechanisms, is attached.
13. Water Proofing & Corrosion Resistance: Additional waterproofing and corrosion resistance measures are applied. This may involve sealants and specialized coatings.
14. Waterproof Testing & Final Inspection: The container undergoes waterproof testing to ensure it's airtight and watertight. A final inspection is conducted to ensure quality standards are met.
15. Material Handling Systems Involved: Throughout this process, various material handling systems are used to move components and the container itself. This can include cranes, forklifts, and conveyor systems.
Each of these steps is crucial for ensuring the durability, strength, and longevity of the steel containers, making them suitable for transporting goods across long distances and various environmental conditions.
