<p>The platform has longitudinal side profiles for holding platform plates. The latter are connected by their edges by continuous angle profiles. The lightweight platform has high torsional stiffness. Means are provided for platform draining. The plates (2) have sandwich structure with sheet metal skin (9) enclosing lightweight core (8). The edges with angle profiles (11, 12) are formed as continuation of the sheet metal skin. The angle profiles are turned in opposite directions on opposite parallel plate edges. The edge profiles formed are hooked together.</p> |
