A high-quality non-rusting steel frame employed as a shop fitting structure consists of polished metal profiles which are joined at their corners by welding. Each metal profile is of square, triangular or polygonal cross-section and has an end face (13) and a longitudinal mantle face (20). The end face of one profile (1) rests against and is welded to the mantle face of the second profile (2). |
