Custom High-Strength Reaction-Sintered Silicon Carbide Square Beams
Engineered for extreme environments, our Reaction-Sintered Silicon Carbide (SiC) square beams provide a robust, high-temperature structural solution for industrial kilns. Manufactured using advanced reaction sintering, these beams offer exceptional mechanical strength and thermal stability, making them the ideal replacement for heavier, less durable supports.
Key Features & Benefits
- Extreme Temperature Resistance: Maintains structural integrity and load-bearing capacity in temperatures up to 1380°C
- High Mechanical Strength: Superior flexural strength at both room and high temperatures, ensuring long-term reliability
- Excellent Thermal Shock Resistance: Withstands rapid heating and cooling cycles without cracking
- Lightweight & Energy Efficient: Reduces the thermal mass of the kiln structure, leading to faster cycle times and significant energy savings
- Long Service Life: Outperforms traditional metal and ceramic supports, reducing downtime and maintenance costs
- Customization Available: We provide tailored sizes and end-processing to fit your specific kiln geometry and requirements

Load-Bearing Capacity for Kiln Design
Our beams are calculated with a bending strength of 250 MPa and a 5x safety factor for reliable operation. The table below shows the load capacity for a 1-meter span. For a beam of length L (meters), use the formulas provided.
Load Capacity Reference Table (for 1-meter span)
| Cross-sectional Dimensions (mm) | Thickness (mm) | Concentrated Load (kg) | Uniformly 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 (m):
- Max Concentrated Load = Table Value * L
- Max Total Distributed Load = Table Value * L
Example: A 50*50mm beam, 2 meters long, can support a total distributed load of 567 kg * 2 = 1,134 kg.
Typical Applications
These SiC square beams are specifically designed as load-bearing components in:
- Shuttle Kilns
- Tunnel Kilns
- Roller Hearth Kilns
- Other high-temperature industrial furnace structures
