WWT – Wind and Water Tight

In the field of transport and storage, the term “WWT shipping container” often appears, which represents a specific classification of containers. Understanding what WWT means and what implications it has is crucial for anyone considering purchasing or using shipping containers for storage or transport. This glossary entry aims to explain the concept of WWT containers in detail, emphasize their characteristics, uses and comparison with other types of containers.

What is a WWT shipping container?

WWT shipping container, or Wind and Water Tight (WWT) shipping container, is a type of used shipping container that is specially classified for its ability to withstand environmental influences such as wind and water. This classification means that the container is free of holes, cracks or leaks, ensuring that it can protect its contents from adverse weather conditions.

Key features of WWT containers

  1. Wind and water resistance: The main feature of a WWT container is its ability to prevent wind and water from entering. This makes it suitable for outdoor storage where protection from weather is essential.
  2. Structural integrity: Despite being used, WWT containers retain their structural strength, making them a reliable choice for various storage needs. The steel construction of these containers ensures durability and resistance to wear over time.
  3. Age and condition: WWT containers are typically several years old, most often around 10+ years, and may show signs of wear such as surface rust or repaired areas. However, these do not compromise their wind and water resistance. The aging process can even increase their robustness if properly maintained.
  4. Door seals and locking mechanisms: A characteristic feature of WWT containers is intact door seals and functional locking mechanisms that ensure the container can be securely closed to protect its contents. Doors are often reinforced to prevent unauthorized access and withstand harsh conditions.
  5. Repeated use and repairs: Although not certified for intermodal transport in their current state (they have expired CSC certificates), WWT containers can be repaired and recertified to meet transport standards if needed. This recertification option makes them a versatile choice for those who may need transport capabilities in the future.

Common uses of WWT containers

WWT containers are versatile and can be used for various applications:

  • On-site storage: Due to their durability and water-tightness, WWT containers are ideal for storage at construction sites, farms or residential properties. They provide a safe and dry environment for tools, materials and equipment.
  • Mobile storage solutions: They offer portable storage solutions for businesses that need temporary storage space. Their mobility allows easy transport to different locations as needed.
  • Modification projects: WWT containers can be modified for specialized uses such as pop-up shops, workshops or even residential spaces (shipping container homes), given their robust structure. Their adaptability makes them a popular choice for creative construction projects, such as converting them into cafes or offices.

WWT containers vs. other types of containers

Cargo Worthy (CW) containers

Cargo Worthy (CW) containers are another classification of shipping containers. They are suitable for intermodal transport and must meet specific standards to ensure they can be safely loaded onto ships. Here’s how they compare to WWT containers:

  • Certification: CW containers have a valid CSC label, which ensures they meet international shipping standards, unlike WWT containers, which require recertification for shipping use.
  • Condition: CW containers may also be used, but tend to be in better condition with fewer dents and rust compared to WWT containers. This makes them a preferred choice for those who need containers in near-perfect condition for transport.

One-trip containers

One-trip or First-Trip containers are nearly new containers that have been used for only one shipping journey from the manufacturing site to their destination. They offer:

  • Aesthetic appearance: These containers are relatively new with minimal wear, making them visually more attractive than WWT containers.
  • Higher costs: Due to their condition, one-trip containers are generally more expensive than WWT containers. They are an ideal choice for buyers who prefer condition and appearance.

AS IS containers

AS IS containers are sold without warranties for wind and water resistance. They are typically in worse condition than WWT containers and may require significant repairs to be usable. Buyers of as-is containers should be prepared to invest in renovations to make them functional.

Factors to consider when purchasing a WWT container

When purchasing a WWT container, several factors should be considered:

  1. Purpose of use: Determine whether the container will be used for storage, modification or potential transport, as this will affect the type of container needed.
  2. Condition: Inspect the container for structural integrity, ensuring that doors, floors and walls are in satisfactory condition. Thorough inspection can prevent future problems related to leaks or structural failures.
  3. Price vs. value: Consider the balance between the container price and its utility value, especially if modifications or repairs are necessary. Budgeting for potential repairs or modifications is essential.
  4. Environmental considerations: Choosing a WWT container is an environmentally friendly choice because it recycles a used product, thereby reducing the need for new materials. This sustainability aspect can be a significant factor for environmentally conscious buyers.

WWT shipping container represents a practical and economical solution for various storage needs, especially for those who want to reuse an existing resource instead of investing in new materials. While they may not be suitable for immediate transport use, their adaptability and robust nature make them a popular choice for many storage and modification projects. Understanding the nuances of WWT containers, including their condition, use and benefits, enables buyers to make informed decisions tailored to their specific requirements.

This comprehensive overview provides a deeper understanding of WWT shipping containers, allowing users to appreciate how these versatile containers can meet diverse needs in commercial and personal contexts.
