Abstract

The construction of substantial metal grilles is described such as those placed over ventilation or lighting shafts and which are intended to support human traffic. Construction of the grille is by longitudinal elements (1, 4) slotted to half their width so that they may be mounted orthogonally to each other. To provide the necessary strength, the portions (5) between the slots are angled in a variety of ways and in particular, bending alternately in different directions increasing rigidity. Grilles constructed in this way need no particular fixing between the elements and are cheap because the elements are simple and may easily be mass produced.
