What nail is better for tile nail groove?

Generally, it can be fixed with small steel nails between 2 cm and 2.5 cm. When fixing, nail should be nailed with ST air gun, and the compressor pressure of air gun should be adjusted to 8 MPa. If you don't want to hurt the wall, you can fix it with some quick-drying glass glue at the bottom of the trough plate, or you can choose to fix it with an expansion plug. After determining the installation position, first punch a few holes in the wall with an impact drill, then insert the expansion plug into the hole, and then fix the trunking plate on the wall with screws.

During installation, the trunking must be kept flat, free from distortion or deformation, and the inner wall cm must not have burrs, which may easily lead to the damage of the wires passing through. At the same time, you should also check whether the joint position of trunking is tight and straight, and whether all accessories are fully installed. The groove cover must be kept flat when installed, and there can be no warping phenomenon. At the same time, the location of the exit must be accurate.
