Everything you need to know before investing in a container — from sizes and grades to delivery, modifications, and pricing.
1. Container Types & Sizes
20ft Standard
160 sq ft floor space. Perfect for small workshops, on-site storage, single-car garage alternative. Payload ~28,000 lbs.
40ft Standard
320 sq ft. Ideal for large storage, multi-purpose use, or splitting into two rooms. Most common for export/import.
40ft High Cube
Extra 1ft height (9'6"). Best for tall cargo, office conversions, or loft-style containers. 2,350 cu ft capacity.
Reefer (Refrigerated)
Temperature controlled for cold storage. Range -20°C to +30°C. Insulated floor and panels.
Open Top / Flat Rack
Removable top for oversized cargo or machinery. Ideal for construction materials, wood, or scrap metal.
Double Door / Tunnel
Doors on both ends for easy access. Great for drive‑through storage or retail pop-ups.
2. Grades & Conditions Explained
New (One-Trip)
Used only once to transport cargo from overseas. Like‑new condition, minimal wear, excellent cosmetics. Best for modifications or high‑visibility projects.
Cargo-Worthy (CW)
Structurally sound for shipping, minor dents/scratches. Wind and watertight, suitable for reloading or rugged storage.
Wind & Watertight (WWT)
Fully functional for stationary storage, no active shipping certification. Some cosmetic blemishes, but 100% weatherproof. Most cost‑effective.
As‑Is / Parts
For upcycling or modified builds requiring structural repair. Not guaranteed watertight.
3. What To Inspect Before Buying
🔍 Structure & Floor
Check for rust perforation on roof & corners.
Marine plywood floor – soft spots indicate rot.
Door gaskets & locking bars alignment.
Cross members – no sagging or cracks.
🚪 Doors & Seals
Rubber gaskets should be pliable, no daylight.
Locking rods operate smoothly, no missing handles.
Hinges without excessive wear or weld cracks.
Test watertightness by looking for light gaps.
4. Popular Modifications
Windows & Vents
Add natural light, airflow for office or tiny home conversions.
Electrical & HVAC
Pre-wired outlets, lighting, A/C units for comfortable workspace.
Partition Walls
Split 40ft into two separate rooms or storage bays.
Insulation & Drywall
Spray foam or rigid board — turns container into climate-controlled area.
5. Delivery & Logistics
📦 Delivery Checklist
Ensure ground access width ≥ 12ft.
Overhead clearance: no low wires/branches.
Level base: concrete pads, gravel, or railroad ties.
Roll-off truck or tilt-bed required.
📏 Placement Tips
Allow 45ft turning radius for 40ft delivery.
Crane or forklift needed for precise placement.
Check local zoning permits for permanent containers.
