This depends on whether you are an inner concave line or an outer convex line. The inner concave requires a groove under the metal strip, and the outer convex requires a wooden strip to buckle the metal strip.

Specific installation method one:
Installation method two of ceiling metal line:
Generally, a groove is left on the top surface and then the metal strip is glued to it. Of course, the groove should be left just right so that there is an interaction force with the metal strip, too loose.
There is also a wooden line smaller than the metal strip on the top surface, and finally the metal strip is stuck up. Generally, the metal strips on the top surface are relatively thin and the height is not high. The recessed strips are easier to handle.
