Engineering Overview & Technical Application

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.

Common Queries

Frequently Asked Questions

Detailed technical and commercial answers from our composite product engineering team.

Acid fumes combine with atmospheric moisture to form acidic condensation on the underside of metal sheets, causing rapid pitting and structural perforation. FRP sheets are non-metallic and chemically inert.

Yes. We manufacture both fully opaque sheets (for maximum shading in hot zones) and translucent acid-resistant sheets (for combined daylighting and corrosion protection).

Our sheets have been deployed in marine ports, salt refineries, and coastal godowns with zero rust or structural degradation over decades.
