The invention relates to a method for the production of gratings. To provide an improved method for the production of gratings, a solution is provided within the scope of the invention, which comprises the following steps in the following order: Hot-dip galvanizing of the bearing-bar strip or the bearing- and cross-bar strip, Punching the bearing bars or the bearing and cross bars and cutting them to length, Pressing of the grating, Banding of the grating. This sequence of steps, in conjunction with modifications within the steps, makes for improved corrosion protection and higher dimensional accuracy. It is no longer necessary to straighten the gratings. |
