Clear Polycarbonate Roofing Sheets Storage
1. Polycarbonate sheet shoube be stored and protected against atmospheric influence like sun, rain, etc.
2. Same length of polycarbonate sheet should be stacked together horizontally or, if different lengths, graded with the longest sheet at the bottom of the stack in order to avoid unsupported overhangs.
3. The stacks should be supported om timber bearers and should not be placed where they can be walked on or driven into.
Polycarbonate Roofing Sheet Packing
As with all glazing materials, care should be exercised when handling and transporting polycarbonate sheet in order to prevent scratches and damage to sheet edges. Each sheet is packaged as follows to minimise the risk of these problems:
* The top face is covered with printed ing
* The bottom face use opal film or neutral film
* The edges of the sheets have colored tape on them
* The sheet should be kept in their packaging until immediately prior to installation
