Date Jan. 23, 1992.To improve the stability of a scaffold board consisting of an upper sheet section and a lower waved sheet section and to reduce its weight at the same time, the lower sheet section is connected with its wave tops substantially pointwise to the upper sheet section. The resultant cavities are foamed with an expanding and curing foam, with the expanding foam squeezing the upper and lower sheet sections apart.
