Panel shaped element i.e. sectional door panel, manufacturing method for building, involves subjecting edge profiles and material forming edge profiles in section plane, that runs parallel to outer surface, to reduced degradation process
摘要
<p>The method involves forming an outer boundary surface (12) of a panel shaped element by a shell (10) made of a metallic material e.g. sheet steel. An insulating body (40) is arranged at an inner boundary surface (14) of the shell that is turned away from the outer surface such that an edge of the body partially overlaps edge profiles (20, 22). The profiles partially overlap the body and protrude from the shell. The profiles and a material of a cross-section surface forming the profiles in a section plane, that runs parallel to the outer surface, are subjected to a reduced degradation process. An independent claim is also included for a device for manufacturing an element.</p>
