Perfect concrete surfaces can be achieved using RAPID column formwork. Through the unique, patented clamping principle, the plywood is simply clamped to the frame, resulting in high quality surfaces without any nail or screw indentations. The chamfer strips effectively seal the corner areas. Using the system, rectangular or square column cross-sections up to 60x60 cm can be continuously constructed without any additional anchors in the concrete. Columns with sharp edges are also possible. Peri.
