Iron sheets as magnetic base
Building a low-cost coatrack is simple:
Screw a coated iron sheet on the ceiling.
The coating is strongly recommended.
On uncoated iron sheets, the magnet is producing black iron dust when moved around and that stains the clothes.
Note from the supermagnete team:
Instead of an iron sheet, you can also screw a metal bar from our shop (available in different colours) on the ceiling.
You could also use inexpensive glue-on metal rods but you should try them out first with light clothing.
