Kiln Structural Support for Continuous Operation up to 1380°C
Dimensions: 30 mm * 40 mm * 900 mm | Wall Thickness: 5 mm
Upgrade your high-temperature kiln with our custom-engineered Reaction-Sintered Silicon Carbide (R-SiC) square beams. Designed for demanding thermal and mechanical environments, these beams provide superior structural support in shuttle, tunnel, and roller hearth kilns. Offering a maximum service temperature of 1380°C, exceptional load capacity, and excellent thermal shock resistance, they are the optimal, long-lasting alternative to heavier conventional materials. Request a quote for custom sizes tailored to your specific kiln geometry.
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.

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
