Before installing Dcon prestressed planks, the beam surface must be checked for smoothness and temporary bracing must be installed at the center of the planks length. In case of a high weight support or a plank with a length of 3.00 m, the temporary bracing is removable only when the concrete topcoat is in a standard strength.
