ABSTRACT:
A grating of metal longitudinal strips (1) standing on edge in parallel with one another and narrower metal cross-strips (3) parallel with one another, is (for the achievement of higher load capacity) produced in such a way that in the longitudinal strips (1) slots (2) of changing width are incorporated, in which the inside width of the slot at the open end of the slot is chosen to the greater than, but on the contrary remote from this end of the slot is chosen to be less than the thickness of the cross-strips (3), cross-strips (3) are inserted into these slots (2) with the application to the strips (1, 3) of a welding voltage serving for the resistance welding, and with the application of pressure in the direction of insertion, so that material driven out from the edges of the slots forms weld beads (9) at the points of intersection of the strips.
