Premium Refractory Anchors for Industrial Furnaces, Kilns & Boilers
At RAS (Refractory Anchor Systems), we specialize in the design and manufacture of high-quality refractory anchors used in the construction and maintenance of high-temperature linings. Whether securing castables, ceramic fibre modules, or refractory bricks, our anchors are engineered for dimensional precision, thermal reliability, and superior holding power.
Anchores available in
- Round and Flat Bar
- Stainless and Inconel
What Are Refractory Anchors?
Refractory anchors are metal components used to mechanically support insulation and refractory linings inside furnaces, kilns, reactors, and incinerators. These anchors prevent lining failure due to thermal expansion, vibration, or gravity, ensuring long-lasting protection of critical high-temperature equipment.
