The protrusions may be spaced bumps or ridges in one surface of each arm, which can be formed by localized depression of the opposite surface of the arm, or tongues bent from each arm. The channels 6 are defined by L-shaped projections 5 upstanding from flanges (4, Fig. 1) of main panels 2<1>, 31 of the walls 2, 3, the flanges (4) being mitred at the corners of the frame. Additional corner connectors 11, which may also have protrusions, are engaged in further channels between the panels 2<1>, 3<1> and the next adjacent projections 5. Spring metal corner clips 10 are also provided. The walls 2, 3 are aluminium extrusions. The connectors 8 are made of aluminium.
