Roofing Sheets

3. Roofing Sheets (FRP & Polycarbonate)

FRP (Fiberglass Reinforced Plastic) and Polycarbonate roofing sheets are lightweight, durable, and weather-resistant roofing solutions. They offer excellent strength, transparency (polycarbonate), and corrosion resistance, making them a preferred choice over traditional materials like asbestos or metal sheets. These sheets are available in various colors, thicknesses, and profiles to suit industrial, commercial, and residential needs.

Unlike steel, GFRP does not rust, making it ideal for marine structures, bridges, coastal projects, chemical plants, and water treatment facilities where exposure to moisture, salts, or chemicals is unavoidable. Their lightweight nature makes them 4x easier to transport, handle, and install, reducing labor costs and improving site efficiency.

Manufacturing

FRP Roofing Sheets are made by laying glass fiber mats in molds and impregnating them with a resin mixture that contains pigments and UV stabilizers. The material is then cured either by heat or through a continuous lamination process, which hardens the sheet. After curing, the sheets are released from the mold, trimmed to size, and surface-coated for UV resistance and durability.

 

Polycarbonate Roofing Sheets are manufactured by melting polycarbonate granules in an extruder and passing the molten material through a die to form the sheet. During extrusion, a UV-protective coating is applied. The sheets are then cooled, cut into required lengths, and finished in different profiles such as corrugated, solid, or multiwall, depending on the application.

Applications

  • Industrial Buildings – Warehouses, factories, sheds, and workshops.
  • Residential & Commercial – Carports, terraces, greenhouses, skylights, and pergolas.
  • Agriculture – Polyhouses, nurseries, and farm shelters.
  • Public Infrastructure – Bus stops, railway stations, walkways, and stadium roofing.
  • Specialty Areas – Swimming pool covers, atriums, and daylighting structures.
