Transparent Polycarbonate Profile Sheet
Polycarbonates are tough, amorphous and transparent thermoplastic polymer. Comprising of carbonate groups linked together, they offer unique engineering advantages. Polycarbonate sheets are almost as clear as glass and more than two hundred times stronger than it. But what makes polycarbonate roofing sheets stand out is indeed their transparency. Another advantage polycarbonates offer is that they are heat resistant and can be combined with flame retardant materials without significant material degradation. Polycarbonate roofing sheets are lightweight and therefore are easy on the columns for structural support.
Polycarbonate sheets expand to a greater per °C of temperature change than any metal. Therefore, it is a good practice to drill fixing holes slightly larger than the shank of the primary fastener. The fasteners should be centered in these holes, allowing the polycarbonate roofing sheets the freedom to expand or contract. In a country like India, where temperature changes can be extreme, this is extremely handy.

Easy Installation
Transparent Polycarbonate Profile Sheet are very easy to install. Just follow the instructions below. Use genuine accessories to protect the sheets and increase their life.
- 1. Firmly place the sharp point of the self fastening fixing onto the crest of the corrugation to be fixed, to eliminate "skidding" or "wandering".
- 2. Commence drilling at 2000rpm to pierce the sheet. Screw engages in steel purling.
- 3. Cutter engages polycarbonate sheet, cuts the expansion hole and centers the screw.
- 4. Wait until the rubber weather seal engages and compresses against the roof sheet and under the fixing head, to stop.
