This is a special ''C'' profile for gypsum board. The “C” uprights (studs) together with “U” guides (tracks) form the gypsum board frames, which are particularly useful for thermal and/or acoustic insulation. This PM profile is a large ''C'' upright and is placed into the wings of the frame, on which the joints of the plasterboard panels are subsequently made. It is a profile particularly suitable for larger and heavier structures. There is the possibility of a special knurling that will ensure greater plaster adhesion. The material, treatments, dimensions, thicknesses and special processing are defined according to customer requirements.
