Shipping Container in Green Color RAL 6007
What is a Shipping Container in Green Color RAL 6007?
A shipping container in green color RAL 6007 is a standardized transport unit, typically of the 20ft General Purpose type (also known as a universal 20-foot container), whose outer surface is covered with a protective coating in a precisely defined shade of RAL 6007 – dark bottle green. This specific shade is not only an aesthetic choice, but primarily a functional protection that fundamentally affects the lifespan, usability, and integration of the container into the environment.
The RAL 6007 container combines robust Corten steel construction, precise color specification according to international RAL standards, and wide range of applications from global logistics to modular buildings such as shipping container homes, warehouses, workshops, and residential projects. The popularity of the RAL 6007 shade stems from its universal appearance, high resistance to dirt, and ability to naturally blend into both natural and urban environments.
Detailed Definition and Context
1. Shipping Container: Construction, Standards, and Types
Structural Properties
- Material: The basis is Corten steel (COR-TEN), a special alloy with high resistance to atmospheric corrosion. The surface patina protects the steel from further rusting.
- Floor: Most containers have a floor made of 28mm waterproof plywood (Marine Plywood), capable of withstanding point loads up to 3,000 kg/m².
- Dimensions:
- 20′ (6.058 m × 2.438 m × 2.591 m)
- 40′ (12.192 m × 2.438 m × 2.591 m)
- Smaller (e.g., 6′, 8′, 10′) and larger sizes exist for special purposes
- Doors: Double-leaf doors with robust locking bars, equipped with rubber sealing and the option to install a lockbox (lock protection).
- ISO Corners: Corner fittings allow safe stacking and handling by crane or forklift.
- Ventilation: Standard ventilation openings prevent condensation and facilitate air circulation.
Standardization
- ISO 6346: The standard establishes systematic marking and coding of containers, enabling their tracking within global intermodal transport.
- CSC Plate: Every container intended for international transport must be equipped with a safety plate confirming compliance with structural and safety requirements.
Container Types
| Type | Use | Characteristics |
|---|---|---|
| General Purpose (Dry Van) | Standard transport/warehouses | Most common, closed construction |
| High Cube | Larger volume | 30 cm higher than standard |
| Open Top | Bulk and oversized cargo | Open roof, tarpaulin |
| Reefer | Refrigerated goods | Insulation + cooling unit |
| Flat Rack | Heavy, oversized cargo | No walls/roof, collapsible ends |
2. Green Color & Coating Significance
Protective Function
- Corrosion Protection: Quality coating protects Corten steel from corrosion caused by rain, snow, salt water, and UV radiation. Especially in coastal areas, the lifespan of the coating is crucial for long-term use.
- Maintenance Reduction: Properly applied coating minimizes the need for frequent repairs and extends the container’s lifespan.
Identification, Branding, and Environmental Integration
- Branding: Major shipping companies use typical colors (e.g., Maersk blue, Evergreen green, Hapag-Lloyd orange) for quick fleet identification.
- Aesthetics: Dark bottle green RAL 6007 is desired for an inconspicuous appearance in nature, near family homes, on farms, or in parks.
- Safety: Special colors (yellow, red) signal containers for storing hazardous materials.
Advantages of RAL 6007 Shade
- Effective masking of dirt and scratches
- Universal use in natural and industrial environments
- Popular for corporate and private projects
3. RAL 6007: Standardization and Properties
What is RAL?
- RAL: German color standardization system (Reichs-Ausschuss für Lieferbedingungen), since 1927. Each shade has a four-digit numerical code and precisely defined composition.
- RAL 6007 (Bottle Green): Saturated, dark green color, officially “bottle green.” Allows precise shade matching across manufacturers and subsequent modifications, which is key for fleet appearance or multiple containers in one location.

Industrial Container Painting Process
1. Surface Preparation
- Removal of dirt, rust, old labels, and paint residue – using sandblasting/shot blasting (minimum cleanliness SA2.5), or sanding and wire brushes.
- Degreasing the surface – using special degreasers, ensuring coating adhesion.
- Repair of minor damage – filling and sanding “hot spots” (welds, corners).
- Thorough drying – painting only on dry surfaces!
2. Primer Coat
- Anti-corrosion base – typically two-component epoxy or zinc-enriched primer, providing active cathodic protection.
- Special attention – bare metal, welds, and corrosion-damaged areas.
3. Top Coat
- Color according to RAL 6007 – polyurethane or acrylic-polyurethane paints with high resistance to UV, salt, and chemicals are used.
- Spray application – for uniform, professional appearance; brush only for details.
- Number of coats – typically 2–3 coats for optimal coverage.
4. Coating Thickness and Quality Control
- Dry Film Thickness (DFT): 80–120 microns is the standard for long lifespan.
- Quality Control: Thickness measurement and visual inspection.
5. Additional Protection
- Roof: Often application of bituminous/epoxy coating additionally (increased protection against standing water).
- Interior: Light colors for better illumination (often RAL 7035).
6. Types of Paints Used
| Paint Type | Properties and Use |
|---|---|
| Two-component epoxy | Excellent adhesion, anti-corrosion effect |
| Polyurethane | High resistance to UV, mechanical damage |
| Acrylic | More eco-friendly, lower VOC, suitable for interior spaces |

Can You Modify a 40ft High Cube Container?
The short answer is yes — you absolutely can modify a 40ft high cube container, and it is one of the most popular container types for modification projects worldwide. But the real question is not whether you can modify one; it is how to do it correctly, safely, legally, and within budget. This guide answers every dimension of that question, drawing on engineering principles, real-world pricing data, and the collective experience of thousands of modified container projects.
Key Takeaway: A 40ft high cube container offers 320 square feet of floor space with an extra foot of ceiling height compared to a standard container — making it the ideal canvas for offices, workshops, homes, retail spaces, and industrial applications. The extra height is particularly valuable when you add insulation and still want comfortable headroom.
Cargo worthy container
If you have ever shopped for a used shipping container, you have almost certainly encountered the term cargo worthy — often abbreviated as CW or CWO (Cargo Worthy Only). It is one of the most important classifications in the container industry, yet it is also one of the most misunderstood. A cargo worthy container is not a container that looks new. It is not necessarily a container that has a valid CSC plate. And it is definitely not the same as a wind and watertight container. This guide explains what cargo worthy really means — from its technical definition and historical origins to the precise structural criteria, inspection process, cost implications, and common misconceptions that trip up even experienced buyers.
Shipping container home
A shipping container home is a residential dwelling constructed from one or more steel intermodal containers — the same standardized metal boxes that transport goods across oceans, railways, and highways. These containers, engineered from corrosion-resistant Corten steel and designed to withstand brutal maritime conditions, are repurposed into fully habitable living spaces through insulation, structural modifications, and the installation of all standard residential utilities. A shipping container home can range from a minimalist 160-square-foot studio built from a single 20-foot container to a sprawling multi-level compound combining dozens of 40-foot high-cube units.
Core Definition: A shipping container home is a code-compliant, habitable structure built from one or more steel intermodal shipping containers that have been insulated, structurally reinforced where modified, and fitted with windows, doors, plumbing, electrical systems, and interior finishes to function as a permanent or semi-permanent residence.
Corner casting steel vs aluminum
Every shipping container in the world — all 40 million of them — rests on eight critical components. Corner castings are the load-bearing blocks at each corner of an ISO shipping container, and they are the universal interface between the container and every crane, twistlock, spreader, and chassis on the planet. When you lift a container, stack it nine high on a ship, or lock it to a truck trailer, every ton of force flows through these fittings.
