Abstract

The object of the invention is a method for manufacturing cellular board, a cellular board, a method for producing cellular board element of steel plate strip, and a production line. A cellular board according to the invention comprises a number of originally separate profiles of plate-like material, which have been fastened to each other. A single profile is intended to form in a finished cellular board a substantially planar first surface projection, a substantially planar second surface projection, a core, which is arranged to interconnect the first and second surface projections. In the cellular board the profiles are fastened to each other so that in the adjacent lamellae the first surface projections are located side by side and form thus a first surface plate of the cellular board, the second surface projections are located side by side and form thus a second surface plate of the cellular board, the profile cores form the core structure of the cellular board.
