Very heavy duty. I am surprised at the high quality for the price. The silver grommets are also high quality. It was 6 inches longer than I needed so I cut the bottom off (where the magnets are.  To reattach the magnets to the newly created bottom length, I cut the circle pockets that contained the magnets from the length I cut off.  I hand sewed the PVC circles containing the magnets, with plastic thread (used for outdoor cushions), to the  bottom of the shortened curtain I created.
