Reinforced shelves for metal shelving units, for supporting on their front electronic labels and/or other peripherals and related manufacturing process

Reinforced shelf for metal shelving unit, particularly for the shelving units whose shelves (B1, Bn) are provided, on the side facing the public, with electronic labels and/or other peripherals, and wherein the shelf on its bottom side has plate reinforcement (T1, Tn), parallel to each other and to the front and rear side (LA, LP) of the shelf itself, characterised in that in correspondence or at the ends of said reinforcements (T1, Tn) there are provided at least a pair of apertures (1, 10) for the passage and support of wiring (D), necessary to connect means (P1) on the rear side of said shelves, to means (P2) on the front side of the same shelf (B1, Bn) for supporting and displaying goods, said apertures (1, 10) being sufficiently distant from the angular bent and ribbed areas of said reinforcements (T1, Tn) so as not substantially modify the characteristics of bend strength and torsion resistance of the same reinforcements. Said apertures (1, 10) are preferably obtained during the manufacture of reinforcements (T1, Tn) and of relative displaying shelves (B1, Bn).
