摘要：Sectional doors for garages, industrial warehouses and the like are formed bypanels joined together in an articulated manner by hinges. Advantageously, the bottomedge of each panel is provided with a tapered lug which, at the end of the rotation duringclosure of the door, abuts against the inclined flank of the edge of an underneath panel.
The abutment thus formed ensures the correct vertical alignment of the panels, therebyproviding the door with a smooth operation and appearance.
