1, Rigidity, Toughness, and Tensile Strength
Because UPVC roof sheet are normally used for the roof, window edge, such as some greater places, so it ought to have accurate rigidity, sturdy durability and robust strength, and these three factors are regularly contradictory, the pursuit of sturdiness can now not require stress and hardness.Therefore, in the buy in accordance to their very own scenario to comprehensively stability the three relations, in particular after a duration of use overall performance will decline, this wishes to be regarded when cloth selection.
2, Heat resistance
Domestic summer time outside temperature is high, anti-corrosion PVC roof tile all day in the sun, is sure to require its excessive warmth resistance, so when the pick out and buy, to pay distinctive interest to the chosen product warmth temperature value, for outside high, indoor can be reduced, however now not due to the fact of low rate pick low warmness temperature products, in any other case UPVC roof sheet handy to tender phenomenon, can no longer play an effect.
3, growing older resistance
The most important impact of formal UPVC roof tile is anti-corrosion. But in outside use, in addition to the sunshine ultraviolet ray, tiles additionally undergo the wind, rain, haze and different factors, these elements have a tendency to make anti-corrosion plastic tile accelerated aging, every vicinity reasons growing old reasons of different, south warm rain, north wind haze, so to pick and purchase in accordance to the particular scenario of the region to choose.
As one of upvc roofing sheet suppliers, Rufu's article above is sum up in the pick out and shopping for UPVC roof sheet want to pay extraordinary interest to the three points, in addition to the pick out and purchase take a look at product thermal contraction rate, warmth contraction fee is too large merchandise after solar publicity handy deformation, warping, have an effect on lovely and can now not recover, and warmness contraction charge small merchandise as lengthy as the temperature does no longer exceed warmth resistance temperature value, simple will now not manifest deformation, warping phenomenon.
