Mwen fèy la ekleraj ak fèy an asye yo anba processes.As bòdi diferan nou tout konnen, fèy la asye ale atravè tout pwosesis la woule frèt, sa ki lakòz yon ang intersecion relativman ti, pandan y ap fèy la ekleraj ale atravè tout pwosesis la tèrmodursisabl, sa ki lakòz yon pi gwo entèseksyon ang. (Si ang lan entèseksyon se twò piti, estrès rete li yo pral trè wo, se konsa ke li pral sijè a fann oswa menm kraze nan itilize.) se poutèt sa, li se pi plis bon lide yo mete fèy la ekleraj sou fèy la asye .

I The daylighting sheet and the steel sheet are under different molding processes.As we all know,the steel sheet goes through the cold rolling process,resulting in a relatively small intersecion angle,while the daylighting sheet goes through the thermosetting process,resulting in a bigger intersection angle.(If the intersection angle is too small,its remaining stress will very high,so that it will be subject to cracking or even breaking in use.)Therefore,it is more advisable to put the daylighting sheet over the steel sheet.
