Quality Testing

Each piece begins as molten brass, precision cast into robust forms, ensuring material density and structural integrity from the core.

Advanced CNC machining refines every curve and edge, achieving architectural-grade tolerances and flawless mechanical function.

Our artisans meticulously hand-polish each surface, achieving the signature unlacquered finish that develops a rich patina over time.

Rigorous testing protocols ensure every fitting exceeds industry standards for durability, operation, and resistance to daily wear.
