Head made of turned steel, base made of die-cast aluminum with a very low copper content. The rod is made of steel. Opal polycarbonate diffuser. No visible screws. The product is subjected to galvanic anodic treatment divided into separate phases: mechanical satin finishing, surface degreasing, anodic oxidation and finally fixing. The product is then painted using the double-pass line method, which allows for the production of a single thick protective layer, which then creates a barrier against weather conditions and UV rays. This allows for corrosion resistance in salt spray. We also encourage you to familiarize yourself with the entire Platek offer, below we have included a link to the entire range of products.Show moreShow less
