A flooring grid comprising a first set of rectilinear, spaced apart, mutually parellel, load-bearing bars (10) and a second set of rectilinear, spaced apart, mutually parallel, transverse bars (12), each of said transverse bars (12) crossing a plurality of load-bearing bars (10) and the transverse bars (12) being forge welded directly to the load carrying bars (10) where the bars mutually cross and wherein the upper edges of the load-bearing bars (10) lie in an upper surface of the flooring grid, wherein at least each load-bearing bar (10) comprises a configuration comprising two opposite end parts (33, 34) the end parts having end surfaces of breadth (B) which are spaced apart by a depth (D), and the end parts being interconnected by a reduced breadth part having two opposite concave curved side surfaces (37) each of which joins the opposite end parts. |
