Abstract

Panne pour toit réalisée en tôle d'acier laminée à froid, destinée à des toits à faible pente de bâtiments industriels, et comprenant une semelle ou membrure supérieure 2 reliée par une aile médiane 4 à une semelle ou membrure inférieure 3. Une bande de renforcement 9 est disposée le long de l'une des moitiés de la membrure supérieure 2 ainsi que le long de la moitié diagonalement opposée de la membrure inférieure 3.Roof purlin made of cold-rolled sheet steel, intended for low slope roofs of industrial buildings, and comprising a flange or top chord 2 connected by a middle flange 4 to a flange or bottom chord 3. A reinforcing strip 9 is arranged along one of the halves of the top chord 2 as well as along the diagonally opposite half of the bottom chord 3.
