Products Description
SiSiC beams feature excellent properties such as high hardness, long service life, high mechanical strength at elevated temperatures, as well as outstanding resistance to oxidation and deformation. They are ideal supporting components for various industrial furnaces and kilns.
Thanks to their excellent thermal conductivity, SiSiC beams significantly help reduce energy consumption.
We offer a wide range of extruded profiles, including hollow sections as well as C- and H-shaped profiles in various dimensions and specifications.
