Load Capacity Reference Table (1-meter span)
| Cross-section (mm) | Wall Thickness (mm) | Max. Concentrated Load (kg) | Max. Total Distributed Load (kg) |
|---|---|---|---|
| 30 * 30 | 5 | 74 | 147 |
| 30 * 40 | 5 | 117 | 235 |
| 40 * 40 | 5 | 149 | 298 |
| 50 * 50 | 6 | 283 | 567 |
| 50 * 60 | 6 | 374 | 748 |
| 60 * 60 | 7 | 481 | 962 |
Calculation Method
For a beam of length L (in meters):
- Max. Concentrated Load = (Table Value for Concentrated Load) * L
- Max. Total Distributed Load = (Table Value for Distributed Load) * L
Example: A 50*50 mm beam, 2 meters long, can support a total distributed load of 567 kg * 2 = 1,134 kg.
Typical Applications
These high-strength SiC beams are engineered as critical load-bearing components in:
- Shuttle Kilns
- Tunnel Kilns
- Roller Hearth Kilns
- Other high-temperature industrial furnace superstructures
