ABSTRACT:
A compound beam, column or rod, consisting of a web (31) of timber or a wood-based board material or plastic material and of one or several flanges formed of sheet metal and affixed to the margin and bent around the web. The flange (32) has been affixed to the web by teeth or equivalent extending substantially through the web, and possibly using glue as aid. The teeth (33,34) bend when striking against the opposite flange metal sheet, producing a permanent joint. The teeth may also be affixed to the opposite flange by welding. A stress may be produced in the flange before it is joined to the web.
