Aluminium alloy base and ground attachment. Head manufactured from milled steel and base in die-cast aluminium EN 44300 with very low copper content. Rod made of stainless steel. Polycarbonate opal diffuser screen. No visible screws. Subjected to galvanic anodizing treatment divided into distinct phases: mechanical satin finishing, surface degreasing, anodic oxidation and final sealing. The product is painted following a continuous two step paint process (epoxy-based primer + polyesterbased colour finish), which allows to generate a single thick protective coating which then generates aprotective barrier against atmospheric agents and UV rays.
