Buliding materials polycarbonate corrugated sheet for greenhouse skylights of WEIERSHA manufacted under the most advanced technology and equipments,adopting polycarbonate corrugated sheet resin as main raw  materials, mixing with anti-UV absorbent and other accessory ingredient . Polycarbonate corrugated sheet have stable performance, not easy to be yellowing and becoming inferior. Also corrugated polycarbonate corrugated sheet owns high ability to absorb and prevent ultraviolet ray approve to 99.9% effectively.

Buliding materials polycarbonate corrugated sheet for greenhouse skylights properties

Light transmission

Fine light transmitting rate approve to 30~ 85%.Weather resistance

With anti-UV weather treatment on the surface, it can prevent the resin from fatigue and yellowing caused by UV. The anti-UV agent on the surface can change the UV absorbed by chemical bond into visible light,and finely stabilize the photosynthesis of plants.Impact resistance  

With the strength as 250 times of the ordinary glass, 30 times as the PMMA sheet, it has less risk of breakageFire retardant  

Fire retardency is up to B2 level (based on the National GB8625-88 test. without flame or toxic gas). Temperature toleration  

Without deformation within the temperature range from-40°C to +120°C.Sound insulation  

It is the best transparent materials for sound insulation engineerings as expressways, factories,etc..Portability  

Light weight,easy handling and drilling, not easy breakage in cutting installation, simple construction and fine treatment.

Applications of Buliding materials polycarbonate corrugated sheet for greenhouse skylights 

• Roofing/wall of agricultrure greenhouse,garden,plant and cultivate;• Roofing/wall of station,yard,airport,bus shelter;• Roofing/wall of fctory building,warehouse,family house;• Roofing/wall of business buildings;• Part of machine, electron, household electrical appliances equipment;• Advertising, decorating, etc.

Notice when delivery, stockpile,installation• Keep PC sheets away from wet cement surface or any alkaline/acid base materials.• Keep frame clean and jointing groove flat and smooth.• Use neutral glass cement and right gasket. Never use gasket of PVC material.• Use electrical tools(tungsten carbide saw) to cut, stabilize PC panels to prevent their vibration. • Install with colourful steel corrugated sheet:When PC roofing sheet is used for natural lighting, it is suggested the PC roofing sheet is lapped under the colorful steel sheet. If use self –drilling screws for fixing,the hole must be pre-drilled, the aperture should be 1,5 times larger than the diamenter of the screw, it is suggested to use roof hook for fixing. Do not tighten the screw strongly, otherwise stress will arise, and local crack on the sheet surface will appear.•About purline span:For the sheet 1.0mmthick, the span of purline is suggested to be less 1000mm.or the sheet 1.2mmthick, the span of purline is suggested to be  less 1200mm.For the sheet 1.5mmthick, the span of purline is suggested to be  less 1500mm.
