Polycarbonate Corrugated Sheet
Impact-Proof
our pc sheets have high impact strength (approximately
250 times that of glass and 3-5 times that of ordinary corrugated sheets) that
makes them virtually unbreakable.
TRANSPARENCY AND LIGHT TRANSMISSION
excellent light transmission .its transparency is
remarkably comparable to that of glass.
Weather-Proof
as sheet's surface have been treated with anti-UV
ray agent to resist resin's fatigue caused by the sun, yellowing on sheets'
surface would not occur. The protective UV coatelayer can maintain excellent
light transmission of the sheets and prevent the sheets from becoming
yellowing.10 years' quality warranty is provided.
Flame-Proof
compared with fiberglass (frp), pc sheets have
remarkable characteristics of flame resistance and extinguishment to
inflammability.
Heat and Cold Resistance no deterioration or
deformation from-20 to 135 centigrade.
Installation and Processing
characteristic of light weight makes the sheets
easy for transportation, handling and installation, with good processing
performance in drilling, cutting and installing without having risks of
breakage.
