How to prevent scratches on tempered glass aluminum doors and windows? The following editor summarizes the points for your reference: (1) Be more careful when stacking, make the bottom edge of the glass touch the support arm first, and then not push the glass horizontally, so that all points on the surface of the glass material can touch at the same time as much as possible. (2) Be sure to put wood or paper in the middle of the glass. Since the glass is stacked on the turnover cart, the glass is relatively unstable. (3) Minimize the number of processing, through assembly line operation.
