what is the role of screws when installing solid polycarbonate sheets

- Aug 03, 2018 -

Because the thickness of the selected solid polycarbonate sheets is different, reasonable adjustment should be made on the setting of screw spacing in different occasions. Too small or too large spacing is unfavorable for the solid polycarbonate sheets itself and its stability. In addition, the size of the screw hole should be considered, because this also involves the different heating, heating, expansion and shrinkage of the sheets in different seasons and temperatures. Under normal circumstances, as long as the screw hole to maintain 2~4mm larger than the screw scope, to leave some space.

It should also be noted that the position of the screw hole during installation should not be too close to the edge of the solid polycarbonate sheets, which may cause the sheets to break. In addition, the tightening degree of mounting screws should be controlled to prevent sheet deformation and stress. In actual operation, it is best not to use self-tapping screws on the solid polycarbonate sheets, otherwise it is easy to generate increasing stress. As long as these principles are followed, the solid polycarbonate sheets must achieve the desired installation effect.
