Our Fire Clay Brick series (SK30 to SK36) is manufactured from carefully selected flint clay with controlled low iron and alkali content, ensuring consistent quality and reliable performance across a wide spectrum of industrial thermal processes. With alumina (Al2O3) content ranging from 30% to 55% and refractoriness up to 1750°C, these bricks offer an optimal balance of thermal stability, mechanical strength, and affordability. They are the trusted standard for carbon bake furnaces, cement kilns, glass tanks, and countless other high-temperature equipment where proven performance and long service life are required.
Select the grade that best matches your temperature and performance requirements.
