The present invention relates to a cold-stamped anti-slip pattern structure of a metal sheet which includes a metal plate and a plurality of raised anti-slip patterns. The metal plate in elongated or square shape has thickness of 2~6 mm, and is preferably made of stainless steel or equivalent material. The raised anti- slip patterns are formed in punching process, arranged in vertically staggered wa y and protrude on the surface of the metal plate. Every raised anti-slip pattern i s inclined at the angle of 45.degree. relative to the metal plate when it is convexly stamped on the surface of the metal plate. The both sides thereof are symmetrically arched and converge toward both ends thereof, thereby creating a leaf shape. The raised top in leaf shape has a flat surface while the rim thereof is constructed as a slop e. Based upon the above-mentioned configuration, the anti-slip effect can be enhanced , it's easy to produce and the structural strength can be increased. |
