Head made of turned steel and base in die-cast aluminium with very low copper content. Rod made of steel (Mesh) or aluminium (Mesh XL). Rod made of steel. Polycarbonate opal diffuser screen. No visible screws. The product is subjected to galvanic anodizing treatment divided into distinct phases: mechanical satin finishing, surface degreasing, anodic oxidation and finally fixing. Subsequently the product is painted by performing a double pass in-line process, which allows the creation of a single thick protective layer which then generates barrier against atmospheric agents and UV rays. This allows to achieve corrosion resistance performance in salt spray.
