Residential rooms are as diverse as their occupants. Metallic finishes, particularly polished nickelled, polished brassed and rosé-gold, are especially popular in residential buildings due to their elegance and timelessness. In tandem with steel and stainless steel doors, they can give any door system an extraordinary, unique charm. Moreover, high-quality materials and alloys of this kind allow for long-lasting, smooth functioning and a flawless appearance.
