Oniir Marketings supplies high-quality fire bricks in Kuwait, suitable for use in industrial applications, made of refractory materials to maintain consistent performance at high temperatures and tough conditions.  The manufacture of the bricks is done using the highest grade of refractory material, which normally contains up to 30% to 80% alumina and has a density of 1.8-2.4g/CM3. The fire bricks possess a cold crushing strength of 20-40 MPa. With such qualities as temperature resistance up to 1400-1600°C, size is 230mm x115mm x75mm, and very low thermal conductivity, the fire bricks can retain heat excellently. Our fire bricks in Kuwait are extensively used in various industrial applications such as furnaces, kilns, boilers, incinerators, and the metallurgical industries, among others.
