ABSTRACT:
An elongate wall frame member (10, 20) comprising: a web portion (11, 21) having a central channel (12, 22) and two base portions (13, 23) on either side of the channel (12, 22); two side edge flange portions (14, 24) both extending substantially perpendicularly and in the same direction from outer side edges of the base portions (13, 23) with the central channel (12, 22) in the web portion projecting in the same direction of the two side edge flange portions (14, 24). At least one end of the elongate wall frame member (10, 20) has part of its web portion (11, 21) notched therefrom so that the elongate wall frame member (10, 20) can be joined at its end to a position along the length of a perpendicularly abutting other one elongate wall frame member (10, 20) whereby the part (18, 28) of the web portion (11, 21) notched therefrom corresponds to either the central channel (12, 22) or the two base portions (13, 23) of the web portion (11, 21) when so joined.
