Use of 45’HC Pallet Wide Double Curtain Side Container
In the dynamic world of global logistics and transportation, efficiency is key. Standard shipping containers have revolutionized the movement of goods, but their rigid, closed construction presents challenges for certain types of cargo and logistics operations. In response to this need, specialized units have emerged that combine the best of different worlds. One of the most innovative and versatile solutions in this field is the 45’HC Pallet Wide Double Curtain Side container.
This glossary article provides a comprehensive and in-depth look at this specific container type, its construction, properties, main areas of use, and its place in the broader ecosystem of intermodal transport.
What is a 45’HC PW Double Curtain Side Container?
45’HC Pallet Wide Double Curtain Side (often abbreviated as 45’HCPWCS) is a specialized intermodal shipping container that combines the robustness and standardized dimensions of a large steel container with the flexibility and easy access of a curtain-sided trailer. Its unique design is a response to the need for fast and efficient loading and unloading of goods that are difficult or impossible to handle through standard front doors.
Meaning of Individual Name Parts
| Abbreviation/Part | Meaning | Technical Notes |
|---|---|---|
| 45′ | 45 feet (13.72 m external length) | Largest commonly used dimension in intermodal transport, competes with standard road trailers, permitted in the EU in combined transport mode. |
| HC (High Cube) | Increased height (2.896 m external, 2.695 m internal) | 30 cm higher than standard container, allows stacking of goods and transport of taller loads. |
| PW (Pallet Wide) | Pallet width (2.44 m internal) | Allows placement of two Euro pallets 1200×800 mm side by side, up to 33 total in one layer, which is the maximum for a European truck. |
| Double Curtain Side | Double side curtain | Side walls consist of robust PVC curtains on both sides, allowing quick side access along the entire length, similar to a tautliner. |
Summary: 45’HC PW Double Curtain Side is the largest standardized cube pallet wide container with maximum volume and capacity for palletized goods, plus unparalleled flexibility for loading and unloading from the side.

Main Structural Elements
- Frame and floor: Robust frame made of CORTEN steel, floor made of laminated plywood (min. 28 mm), designed for repeated use by forklifts and resistant to moisture and mold. Floor load capacity typically 7,000 kg per m².
- Roof and front walls: Steel profiled roof with leak protection, solid front wall protecting the front of the cargo.
- Rear doors: Standard double-leaf doors with solid closure and double sealing, ISO locking system (possibility of sealing).
- Side curtains: Made of PVC with a minimum weight of 900 g/m², UV stabilized, resistant to tearing and water, suspended in the upper rail with the possibility of quick retraction along the entire length.
- Tensioning and securing system: Curtains tensioned with steel cables or straps with ratchets, lower edge of curtain equipped with hooks to secure to the frame, minimizes flapping and water/dust ingress.
- Sliding posts/internal gates: Posts typically aluminum or steel, removable, provide increased lateral stability and protect cargo when the curtain is opened.
Main Uses and Applications
45’HC Pallet Wide Double Curtain Side finds application where standard containers are insufficient:
Intermodal transport of palletized goods
- Ideal for European logistics (in line with Euro pallet dimensions).
- Possibility of combining road, rail, and maritime transport without cargo transshipment.
- Side access saves time in distribution centers without ramps, cargo can be loaded and unloaded with forklifts along the entire length.
Transport of oversized and long cargo
- Suitable for profiles, pipes, wood, construction components, engineering parts.
- The ability to handle from the side is crucial for heavy or long objects that would not fit in a classic container or would be difficult to store this way.
Efficient storage (storage container)
- Industrial plants, construction sites, manufacturing areas – possibility of immediate access to any part of stored goods.
- Ideal for temporary warehouses where quick material movement and frequent inventory rotation are needed.
Events and mobile solutions
- Quick conversion to mobile shop, exhibition stand, service workshop, event facilities.
- Curtains can be easily pulled back and the space opened to the public or workers.
Just-in-Time (JIT) Logistics
- Reduces production downtime due to easy access to specific parts or deliveries at precisely scheduled times.
- Enables quick response to changes in the supply chain.
Advantages and Disadvantages
Advantages:
- Maximum loading flexibility: Ability to load from the side, quick handling of pallets and awkward cargo.
- Time optimization: Significant reduction in loading/unloading time, important for just-in-time logistics.
- High capacity: Combination of length, height, and width means one of the largest cargo volumes on the market.
- Full intermodality: Suitable for road, rail, and maritime transport.
- Cargo protection: Complete coverage against weather conditions, comparable to standard containers.
Disadvantages:
- Lower security: Curtains can be damaged or cut, lower level of physical protection against theft than steel walls.
- Higher purchase price and maintenance: More complex construction, curtains and mechanisms require regular inspection and possible repairs.
- Limited stacking capability: Curtain sides do not provide the same support as solid walls, limitations when stacking on ships or in warehouses.
- Lack of thermal insulation: Standard models are not insulated, unsuitable for temperature-sensitive goods.
Comparison with Other Container Types
| Container Type | Advantages | Disadvantages | Typical Use |
|---|---|---|---|
| 45’HC PW Double Curtain Side | Loading flexibility, capacity, intermodality | Security, higher price, maintenance | Pallets, long goods, events |
| Standard 40’/45′ HC | Security, lower price | Loading only from rear | General transport, storage |
| Open Top | Loading from above (crane) | Limited protection, unsuitable for pallets | Machinery, bulk materials |
| Flat Rack | Extreme dimensions, heavy loads | No protection, no flexibility | Machines, oversized units |
| Reefer (refrigerated) | Temperature control | Higher price, energy intensive | Food, pharmaceuticals |
| Tank Container | Liquids, gases | Limited use | Chemicals, food liquids |
Related Terms and Current Trends
- High Cube Pallet Wide (HCPW): Combination of high volume and width for pallets, key for optimizing logistics in Europe.
- Shipping containers sale: Sale and rental of these containers is the domain of specialized companies, most manufacturers offer new and used variants according to customer needs.
- Dangerous goods: Transport of hazardous substances in curtain-sided containers is subject to strict regulations (ADR, IMDG), requiring compliance with packaging, labeling, and securing.
- Intermodal transport: Trend of combining different types of transport without cargo transshipment, significant shift towards reducing the carbon footprint of transport.
Trends and Innovations
- Automation and digitalization: Real-time tracking of container location and condition using IoT devices, sensors for measuring humidity and temperature in curtain-sided containers.
- Enhanced security: Development of new curtain materials with higher puncture resistance, possibility of tracking curtain opening/closing.
- Custom modifications: Adaptations for events, mobile shops, warehouses with shelving, special fastening systems for transporting atypical oversized parts.

What are the widths of a shipping container
The width of a shipping container – 2.438 m – is one of the pillars of global logistics. Thanks to its standardized size, it is possible to transport goods across continents efficiently, safely and without any problems, stack containers high and optimize handling. When choosing a container, it is necessary to take into account not only the width, but also the length, height, type (standard vs. High Cube) and any special requirements – for example, Pallet Wide or Reefer.
What are the tolerances for unevenness of a shipping container?
Shipping container unevenness tolerances are the basis for safe, efficient and standardized transportation and storage. Each container must meet precisely defined limits for deformation, dents and structural damage. These limits protect not only the value of the cargo, but also the lives of logistics workers and the stability of the entire logistics chain. Keeping containers within tolerances is an investment in the safety, longevity and reliability of your transportation solutions.
