    (54) Improved garage door


    (57) An improved garage door, devised for manufacture on a large scale with a significant reduction in energy requirements and/or materials consumption as compared with doors made by many existing methods, is in the form of a generally rectangular metal from (10) and one or more metal panels (12) located in the frame. The panels (12) are secured to each other and/or to the frame (10) by a multiplicity of connections (14) at intervals along their abutting lengths and each connection (14) takes the form of a localised non-piercing stretching of the two metal components into a laterally-enlarged protrusion (20, 21; 26, 27) wich holds the two components together.
