Metal spinning technology

Metal spinning technology gives Ratio Pendant Lamps a recognisable shape, blending simplicity and elegance. All variants in the series are crafted from the same sized metal plate, emphasising the efficiency of this production method. The process involves shaping metal blanks on a lathe, resulting in a unique, visually appealing form. This combination of visual appeal and functionality makes these lamps a refined addition to any space.
