Beams Kiln Car Construction
Beams are employed to provide structural support for a wide range of high-temperature kiln and furnace applications. Beams are available in a range of different materials, including:
A large selection of cross-sections, wall thickness, and lengths are available, with cross-sections as small as 12.5 mm and lengths up to 3,500 mm. Beams are formed using slip-casting or extrusion processes, suitable for use ‘as-is’ or finished according to customer’s required tolerances.
