Abstract
Non-slip step. Particularly ideal to be used in train wagons, public worksites or any installation and other similar locations in which metal steps are used. The step of the invention has a base body (1) made of bronze, aluminium, copper or other similar material of any type of steel or metal, on whose upper or operative side (2) covering it completely or partially incorporates a layer of grains (3) of non-slip material such as corundum that is partially embedded in the heart of the base metal (1) so that the latter fills the gaps defined between the grains (3) which emerge slightly to the outside with respect to the general place of the base part (1) and are housed in its core so that at least the thickness of the grains (3) completely embedded in the base metal (1) is equal to the thickness of said grains.
