Description
Shipping container corner castings (also called container corner fittings) are critical for secure stacking, lifting, and transport. Whether you’re replacing damaged corners or verifying shipping container corner casting dimensions for a custom build, this guide covers.
1. ISO 1161 Standard: Corner Casting Dimensions
The ISO 1161 standard defines exact shipping container corner casting dimensions to ensure global compatibility with cranes, trucks, and stacking systems.
Key Measurements
| Dimension | 20ft Container | 40ft Container | High Cube |
|---|---|---|---|
| Length (A) | 178mm | 178mm | 178mm |
| Width (B) | 162mm | 162mm | 162mm |
| Height (C) | 118mm | 118mm | 118mm |
| Hole Diameter | 30mm | 30mm | 30mm |
2. How to Measure for Replacement Corner Castings
If your shipping container corner is damaged, follow these steps:
Step 1: Check for ISO Compliance
-
Verify castings have ISO 1161 markings.
-
Non-standard corners may cause stacking failures or crane accidents.
Step 2: Record Critical Dimensions
-
Length/Width/Height (Use calipers for precision).
-
Hole Alignment (Ensure 30mm diameter).
-
Steel Thickness (Minimum 10mm for durability).
Step 3: Match Material Grade
-
Corten Steel (Best for corrosion resistance).
-
Cast Steel (Cheaper but less durable).
3. Signs You Need Replacement
? Cracks or Warping (From overloading or impacts)
? Corrosion (Especially in marine environments)
? Hole Wear (From repeated twist-lock use)
4. Frequently Asked Questions (FAQ)
Q: Are all shipping container corners the same size?
A: Yes, per ISO 1161, standard 20ft/40ft/HC containers share identical corner dimensions.
Q: Can I weld a damaged corner instead of replacing it?
A: Only if the damage is superficial. Cracks require full replacement for safety.
Q: Is there any discount for bulk ordering?
A: Yes, there are discounts for bulk orders
