Abstract

Une palette (1) comprenant un corps (2) conformé en une forme prédéterminée et un revêtement (3) formé à la surface du corps (2). Le corps (2) est, par exemple, fabriqué en métal. Le revêtement (3) est un revêtement antidérapant ayant un angle de début de glissement de 15° ou plus. Le revêtement (3) est préférablement normalement formé de peinture en poudre utilisant au moins une sorte de résine polyoléfine en tant que composant résine, choisie parmi un groupe formé par la résine polyéthylène, la résine polypropylène, la résine copolymère éthylène/acide acrylique et la résine copolymère éthylène/acétate de vinyle. La palette (1) démontre une excellente performance antidérapante pour éviter le glissement d’un article, l’effondrement de la charge et la chute d’un ouvrier et peut être fournie à moindre coût.
