Shengyu fèy do-kay résine gen yon koyefisyan nan ekspansyon lineyè nan 0.0000493 / ℃ .Yo nan lòd yo ki pèmèt nòmal ekspansyon lineyè nan fèy la, nou konseye fè egzèsis yon twou ak dyamèt 2-3mm pi gwo pase sa yo ki an vis la, ak Lè sa fè fixation a fè pou evite nenpòt dilatasyon nan sheet.Please a pa fè fixation a twò byen sere.

Shengyu resin roof sheet has a coefficient of linear expansion of 0.0000493/℃.In order to allow normal linear expansion of the sheet，we advise to drill a hole with diameter 2-3mm bigger than that of the screw，and then make the fixing to avoid any dilatation of the sheet.Please don’t make the fixing too tightly.
