Dimensions of up to 5 m x 2 m and special thicknesses can be supplied upon request. It is used both for walls and slabs, the concrete finish shows a timber structure. 3-S panels with a width of 0. 5 m are available either in yellow without edge protection profile or in red-brown with front-end aluminum edge protection profile.
