What is a shipping container? Comprehensive definition
Shipping container is a large, standardized steel box designed for transporting and storing goods. Officially it is called an intermodal container, whose essential feature is the ability to be used across various modes of transportation – sea, rail, and road – without the need to rehandle the cargo. This principle, known as containerization, caused a revolution in global trade from the mid‑20th century – dramatically reducing transport costs, increasing efficiency and safety of shipments.
Production and materials: Containers are primarily manufactured from high‑strength Corten steel (also known as “weathering steel”), which due to its composition forms a surface passivation layer and is therefore extremely resistant to corrosion, especially in aggressive marine environments. Modern containers are designed with long service life, high load capacity, and resistance to mechanical stress during stacking and handling in mind.
Key characteristics of a shipping container:
| Characteristic | Description |
|---|---|
| Standardization | Most containers conform to ISO standards (especially ISO 668, ISO 1496, ISO 1161), which enables easy stacking, handling (cranes, forklifts) and transport worldwide. The most common lengths are 20 ft (6 058 mm) and 40 ft (12 192 mm), width 2 438 mm, height standard 2 591 mm (High Cube 2 896 mm). |
| Durability and service life | Corten steel ensures long service life – containers typically last 25–30 years even in harsh conditions. |
| Safety | Massive steel construction, robust doors and sophisticated locking systems provide protection against burglary, damage and vandalism. |
| Intermodality | Corner castings allow safe lifting, stacking and attachment on ships, trains and trucks. |
Anatomy of a shipping container
At first glance a simple steel box is actually a precisely engineered technical structure. Understanding the individual parts is the key to exploiting its strength and versatility.
Key structural components:
| Component | Description and technical details |
|---|---|
| Corner castings | 8 reinforced corners made of cast iron according to ISO 1161; they determine strength during stackingand are the main points for crane or twist‑lock attachment. Without them containers could not be efficiently transported and stacked. |
| Frame | Main load‑bearing structure of rolled steel profiles, providing rigidity and dimensional stability even under full load. |
| Corrugated walls | Walls of corrugated steel (typically 1.6 mm – 2.0 mm thick), welded to the skeleton to increase strength without unnecessary weight gain. |
| Flooring | Usually marine plywood 28–30 mm thick, impregnated against moisture, pests and rot. Some types have steel or composite floors. Floor load capacity commonly exceeds 2 000 kg/m². |
| Cargo doors | Double doors on one of the short sides, with multi‑point locking, weather sealing and optional sealing. Designed for easy handling even in freezing temperatures. |
| CSC label (Container Safety Convention) | Mandatory metal plate confirming that the container meets international safety standards for transport. The date of the last inspection and its validity are crucial for international shipping. |

Condition and quality of shipping containers
When purchasing a shipping container, it is essential to distinguish several quality categories that correspond to condition, history and potential further use.
| Quality/category | Description and use |
|---|---|
| New (One‑Trip / IICL 6) | Container used only for a single trip from the factory (usually Asia), virtually without wear, maximum service life, suitable for representative warehouses, residential and commercial conversions. Highest IICL 6 standard. |
| IICL 5 | Minimally used, meets Institute of International Container Lessors (IICL) standards; suitable for demanding customers. |
| Cargo Worthy (CW) | Used but certified for international transport (valid CSC label), may have cosmetic defects (dents, surface corrosion), always wind‑ and watertight. |
| Wind and Watertight (WWT) | Used, no longer approved for transport, but guaranteed wind‑ and watertight – ideal for storage, workshops, garages, conversions without transport needs. |
| Decommissioned (AS IS) | Decommissioned, sold as‑is (may have holes, significant corrosion), suitable for projects with major modifications or temporary use. The cheapest option. |
