The walkway is a continuous profiled metal plate, the small beams (4) have flat enlargements (6) at their base and a top open structure (5) spaces the beams. The solid part (7) of the small beam compression face is moulded to increase its fire resistance. - The end beams of each small plate forming the walkway have elastically deforming complementary C and V profiles at their lower ends for the interconnection of the small plates.(2/2)
