Trims are the decorative molding that frame the window or door.
Stone moldings and trims along with their profiles are also called "stone lines" or "special shapes" in general. Stone moldings and trims can be used for a variety of applications in any given architecture projects. They can be used as general molding, stone trim, stone crown molding, threshold, base molding and even simple door or window surrounds. Stone moldings can be made in marble, granite, possibly in sandstone, travertine and limestone.
