SHEET METAL PLATE WITH RELIEFS FOR CREATING INDUSTRIAL FLOORING OVER WHICH TRUCKS ARE TO RUN, ENGRAVED CYLINDER FOR OBTAINING SUCH SHEET METAL PLATES BY ROLLING

摘要

Sheet metal plate for creating flooring, particularly of industrial vehicles, over which trucks are to run, having a plurality of patterns, the maximum height of said reliefs ranging between 0.2 and 1.5 mm, said reliefs having a friction surface which has a mean width of at least 1 mm, in which said reliefs are arranged in a plurality of aligned groups of reliefs all of the same shape, the same orientation, and with their centers of gravity substantially aligned in one and the same given direction (D), the minimum distance, measured in said direction (D), between two adjacent reliefs of one and the same aligned group being less than 6 mm. The direction (D) in which the aligned groups are aligned advantageously coincides with the direction (De) in which the trucks run.
