Acid Proof/Resistant Bricks Manufacturers

Acid proof bricks are highly resistant to chemical attacks of acid and alkalies. Dues to their chemical resistant nature they are generally used for masonry constructions of floorings subject to acid attacks, lining of chambers and towers in chemical plants, the lining of sewers carrying industrial effluents, etc to prevent deterioration of the surface by acid and other chemicals.

We are the leading Acid resistant / Chemical Proof / Chemical Resistant / Alkali Resistant / Acid Proof Bricks manufacturers & suppliers in Alwar, India. The Acid Proof bricks are made using low ferric, high-grade clays along with quartz, felspar, and other raw materials. At Refmon Industries, these acid or fire bricks are pressed on 150 MT presses and fired in tunnel kilns at over 1200°C temperature, which gives them high crushing strength and extremely long life.
