Self-tapping screws are treated with anti-rust paint, and nail caps are used conventionally. If you spray anti-rust paint by hand, it will be better than the point.
It depends on what material you use for the ceiling, if it is gypsum board, then you must be careful, it is very dangerous!
After a long time, there will be problems, because gypsum board is quite heavy, nails alone are far from enough, some gypsum board ceilings also have to be painted with white latex, and nails alone are the easiest to crack, but generally can't fall down, hehe.
It is best to do anti-rust treatment, otherwise rust will appear after the batch of putty is soaked in water, and the white will turn yellow to expose traces.
1. All self-tapping screws are used in occasions where the bearing capacity is not large, and they cannot bear a lot of force. It is recommended that you go to some home after-sales website platforms (such as platforms like Master Wan) to publish tasks to find masters, nationwide coverage, and task orders are pushed nearby.
