Permanent Corrosion-Proof Roofing for Severe Acid, Alkali & Marine Environments
Operating out of our dedicated Bhiwandi facility since 1962 with zero distributor markup.
In chemical plants, electroplating sheds, dye manufacturing units, galvanizing lines, and coastal warehouses, acidic fumes and airborne salts dissolve standard metal and GI roofing sheets within 12 to 24 months. Rawji Exports' chemical-resistant FRP roofing sheets utilize premium vinyl ester and isophthalic resins that remain completely unaffected by aggressive corrosive atmospheres.
Rigorous quality testing and dimensional accuracy conforming to national and international composite standards.
