    Data t of HIGOAL TIANYANG panel tested in Europe

	<< Accelerated aging performance of FRP panels with film and gel coat added on surface      * 1000 hours    =3 years in north Europe & northeast in China    =2 years in south Europe (East china, south china)    =1 year in Florida in America(Nanhai, china)
	<< A comparison of the Yellowness index change of GRP/FRP systems     The aging of FRP products is too long to be tested, while the yellowness can be found in short years.
	<<As micrograph shown, the 301 film has been eroded and the fiberglass exposed on surface   Fiberglass with 301 film added become aged after 4000 hours
	<<As the micrograph shown: taking F4 film, fiberglass is not eroded even when become aged after 4000 hours. Fiberglass with F4 film added become aged after 4000 hours F4 film is an aging resistant protection film that has PTFE basis, HIGOAL imported only.
	In 1998, HIGOAL became the first company that issued <<Guaranty of 10 years quality>> in domestic FRP industry. As 9 years passed by, HIGOAL has improved the production of FRP skylight panel to mechanical line and developed a new strengthened skylight panel in 2006, however, we have never changed our primary commitment: guaranty of 10 years quality. It is because that our skylight panel has been spread from Guangdong area to whole China and Asia.

As every one knows, the usage period will be affected by the environment and weather, however, our quality guaranty will be issued all over the world. We have been insisting on that a responsible enterprise will not sell the quality guaranty only but will know the environment very well and own a developing technique.Since the strengthened skylight panel has been brought into the market for a year and acknowledged, HIGOAL decide to provide <<Guaranty of 15 years quality>> for the general skylight panel from July 2007.
