Die-cast body and flange made of aluminium alloy with very low copper content. High reflection anodized aluminium reflector. A4 Stainless steel screws. Gore valve to prevent condensing. 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 you to generate 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. PMMA diffuser Pre-treatment with atmospheric pressure plasma is carried out on the surface before gluing of the diffuser on  products.
