What Size and Grade Container Should I Buy?
Commercial containers are most commonly available in 20-foot and 40-foot lengths:
- 20-foot containers: Suitable for smaller storage needs or sites with limited space, such as jobsite storage, tools and equipment, seasonal inventory, or compact storage solutions.
- 40-foot containers: Best for larger inventories or when you want maximum capacity in a single unit, including bulk materials, retail overflow, or long-term on-site storage.
Container grade affects durability and suitability:
- One-Trip: Nearly new, high-quality containers with minimal wear; ideal for long-term use, modifications, or applications where appearance and structural condition are a priority.
- Cargo Worthy: Used containers certified for safe transport; ideal for shipping, export, or secure storage where functionality matters more than cosmetic condition.
- Wind & Water Tight (WWT): Provides basic protection; ideal for short-term or light storage but may require extra maintenance for long-term use.
Selecting the right size and grade ensures your container fits your storage needs. Explore storage container options to see what’s available.
What Should I Inspect Before Buying a Container?
Before committing to a purchase, inspect the container for these key details:
- Rust and corrosion: Check corners, doors, and edges.
- Floor condition: Ensure it’s strong enough to handle your inventory.
- Doors and seals: Confirm doors close securely and seals prevent water intrusion.
- Roofline and structure: Look for dents or warping that could compromise strength.
