Profile with coextruded bead made of plastic having reduced expansion and shrinkage
The extruded strip (1), comprising functional (7) and fixing (2) sections with a base (3) and sides (4, 5) forming a channel (6), has the fixing section made with at least one coextruded rib (18) of a plastic material with a low expansion/contraction coefficient. The rib, made from a filled or reinforced plastic, extends along virtually the whole length of the strip and is designed to position it or correct linear deformation. A variant of the design can have two coextruded ribs along opposite sides of its fixing section, at least one of which is located along a part of the extrusion that is not visible once it is fitted.
