A frame member (5) for a framed panel (1) of the type having a rigid frame (2) and an infill member (3). The member (5) is of open section, and has at least two section portions (8a, 8b, 8c), wherein at least one portion (8a) has at least one crest (9). <??>The crest ensures that another component of a framed panel, such as transverse section of wire, only makes contact with the frame member in a limited area. This in turn results in a high welding pressure when such a component is welded to the frame member, leading to a higher welding power and therefore requiring a shorter welding time. With shorter welding time, less heat is generated in the surrounding material of the frame member, therefore preventing damage of any surface treatment such as galvanizing. <IMAGE> |
