Abstract

The metalwork grille is mfd. by means of prefabricated sections. Each ornamental grille section is made by cutting a lengthwise slit (3) in a flat bar of rectangular cross-section, so that the two sides of the slit (3) are positioned along the centre plane of the bar. The two equal strips (4, 5) on each side of the slit (3) are bent parallel to the centre plane of the bar, so as to form a space between. On each side of the space is a straight part in the middle of which is cut a notch (10) extending crosswise halfway across the bar, and lengthwise to an amount equal (11) to the thickness of the bar (12). The sections are interlocked by means of the notches (10), and welded, riveted bolted or pinned together.
