The mounting frame I ordered because the material designation "zinc die casting" indicates a stainless steel version. Unfortunately, I was mistaken, because the delivered construction is made of steel sheet and in a wet room is not old. Granted, the pivotable part is made of thicker steel plate, but it also looks rust not look good. The delivery goes back and instead I order the "spotlights" Timo "chrome look - 230V high - voltage GU10 without lamps - 9s set of lighting and lighting technology". As you can see in the photos that it is a die-cast part.
