Key Features & Benefits
  • High-Temperature Structural Integrity - Maintains strength and dimensional stability under continuous operation at temperatures up to 1380°C.
  • Superior Mechanical Strength - High flexural strength at both ambient and elevated temperatures ensures reliable, long-term performance under load.
  • Excellent Thermal Shock Resistance - Withstands rapid heating and cooling cycles without damage, reducing downtime and maintenance.
  • Lightweight & Energy Efficient - Lower thermal mass compared to traditional supports enables faster kiln cycling and significant energy savings.
  • Extended Service Life - Outperforms metal and many ceramic supports in high-temperature environments, reducing replacement frequency and total cost of ownership.
  • Full Customization - Available in tailored dimensions, lengths, and with precision end-finishing to integrate seamlessly into your kiln design.

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
