Portfolio Brief
Fire Clay & High Alumina Bricks
Fire Clay Refractory Bricks are produced using a variety of fireclay and ceramic and refractory materials. The alumina content of these bricks falls between a range of 25% to 50%
High Alumina Refractory Bricks with alumina content 50% to 90% are manufactured by utilizing various high grade raw materials which include Bauxites (as main raw material), ceramic clays (contain the aluminosilicate mineral), refractory grains, phosphate solution (used in phosphate bonded bricks), and other binders.
High-quality Fire Clay and High Alumina refractory bricks are what we manufacture and export in large quantities. Janta Overseas has successfully exported bulk refractory bricks and professional refractory material solutions to various industrial furnaces in oversea markets. We are manufacturing High Alumina Fire Bricks at our highest capacity, thanks to our highly qualified workforce and state-of-the-art equipment.
