Corrosion-resistant & so it requires less maintenance. Easily corroded & maintenance by doing re-painting.
High strength & stronger than GI sheets. FRP corrugated sheets do not deform under impact loads. Less strength & easily deform under high impact loads.
Light in weight and it weighs only 25% as compared to GI. Heavier as compared to FRP sheets and requires another lifting equipment to lift the GI sheet.
Less thermally conducted and does not expand or contract like metals. FRP sheets are safer to use as compared to metals. Thermally conducted and it undergoes expansion and contraction.
Longer life and are maintenance-free. pigments are added into the resin so it does not require repainting. Less life and requires repainting which adds to the cost of GI sheets.
used majorly in chemical industries, marine applications, industrial sheds. Difficult to use in chemical industries, marine applications where there is frequent corrosion which affects the life of GI sheets.


We offer a wide range of machine-made FRP products, which are manufactured using superior grade raw materials like plastic, fiberglass cloth, fiber glass sheet, fiber glass sheet panel, metal roofing panel, fiberglass mat, fiberglass yearn, resin to ensure durable performance at client’s end.
