<p>A metallic structure comprises a plurality of load bearing members (11-14) in which through bores (15, 16) are formed and through which transverse bars (17, 18) are located. The load bearing members (11-14) are deformed in the vicinity of the apertures formed therein causing interlocking relationship between the load bearing members and transverse bars to form a substantially rigid structure suitable for metallic flooring. A method of manufacture and apparatus for manufacturing the metallic structure is also described. </p> |
