Gratings, in particular for use as a shelf for plate racks or heavy duty racks, with two longitudinal sides and cross members arranged between the longitudinal sides

摘要

The present invention relates to grates, in particular for use as a shelf for plate shelves or heavy duty shelves, with two longitudinal sides and arranged between the longitudinal sides cross members. Such grates must withstand high loads and are expensive to purchase due to the material costs used. The invention is therefore based on the object to provide a grate that is easier and cheaper to manufacture than the prior art, without affecting the structural stability and load capacity. The object of the invention is achieved on the one hand by a grate, in particular for use as a shelf for plate shelves or heavy duty shelves, with two longitudinal sides and between the longitudinal sides arranged cross members, characterized in that the longitudinal sides are formed in cross section as a Z-profile, wherein the Z Profile comprises a first leg, a second leg substantially parallel to the first leg and a connecting part connecting the first and second legs, and at least two of the transverse beams have an open profile in cross-section, in particular a U-shaped or V-shaped profile aligned open side to the underside of the grate, wherein each of these cross member has at least two punches at each end, wherein in each punching the first leg of the Z-profile is arranged and is connected via a connection method fixed thereto.
