GRP / POLYCARBONATE PROFILE SHEETS FOR SKLYLIGHT AND ROOFING APPLICATION For all kinds of roofs, especially Industrial roofing (Trapezoidal/ Corrugated roof sheets), natural light penetration into the sheds is essential to ensure that operations that take place are up to the mark. In fact, natural light saves on energy costs and provides a better environment. GRP/ FRP Skylight sheets are widely accepted. The profile of the skylight sheets should be the same as the metal sheets of a shed. GRP/ FRP Translucent sheets can be made available as per the existing roof sheet profile (subject to qty.)
