PC transparent Bottom price polycarbonate corrugated sheets for roof

Product Description

1. Desctription:
PC corrugated sheet is made from polycarbonate (PC) material, general type: **0mm, **0mm, **0mm, **0mm, **0mm, commonly using and matching with color-coated steel are generally **0mm and **0mm, PC corrugated sheet has excellent mechanical stability; anti-yellowing, aging, and the test proved that *9.9% of UV rays can effe-ctively absorbed and insulated. It can maintain the stability of the physical indicators in the range of **0℃to **0℃. ***0 hours of artificial weathering test , yellowing is 2, but transmittance reducin is only 0.6%. Linear expansion coefficient: 7 × ***5cm / cm /℃, it's smaller in plastic material. According to National standard GB*******5, PC Solid sheet is rated Class B1, self-ignition point is **0℃, it will self-extinguishing apart from fire, and does not produce poisonous gases when burned, and not contribute to the fire spread,etc.
PC Corrugated sheet surface coat a UV layer protection, blocking the penetration of ultraviolet rays, ensure that the sheet will not be significant yellowing during guarantee period, so as to ensure the sense of beauty of light 
transmittance.
 
2. Specification:

2. No use of  organic solvents or glue composed from it, nor painting.
3. Keep frame clean and inserting groove furface flat. Use soft cloth or sponge with neutral cleaner wipe, then wash thoroughly with water.
4. Select the correct sheet thickness, allow radius of curvature.
5. Be pre-drilled before fix screw, the hole size is 1.5 times than that of screw diameter. Too tight screw will cause stress.
6. Reserve space and pay attention to insert depth. Expansion of value = coefficient of linear expansion × length × maximum temperature  
    change (linear expansion coefficient of PC sheet: 7 × ***5mm / mm /℃).
7. Use neutral silicone sealants and suitable gasket material, plastic and suitable liner material, the material can not be used as PVC, PVC 
    material is forbidden.  
8. Use power tools (Tungsten carbide saw blade) when cutting, fix the sheet well to avoid vibration.
