High Alumina Firebricks, Blocks & Shapes

 

Fire Bricks are a basic requirement in the  building  of chemical plants, refineries, power generation  plants,  cement and steel plants. We supply firebricks ranging from 30% to 80% Alumina in all sizes and shapes. Our refractories are made by dry pressing method and firing in electronically controlled tunnel kilns. We also supply dense and low ferrous fire bricks.
