SISIC Beam Overview
Silicon carbide beams, also known as reaction bonded square beams, special-shaped beams, or support columns, are used as load-bearing structures in tunnel kilns, shuttle kilns, and roller kilns.
They offer excellent high-temperature strength, thermal shock resistance, and oxidation resistance.
Durable and deformation-free over time, they are ideal for sanitary and electrical ceramics, helping reduce energy use without adding kiln car weight.
