We design finishes
that age with character.

Copper, bronze and aluminum. Noble material
transformed with sensitivity.

KERAI. Materials.

Every finish is a conscious decision.

At KERAI, we choose copper and bronze not only for their technical performance, but for their symbolic weight. They are noble materials that evoke presence, permanence y belleza atemporal.

Copper offers a thermal conductivity of 398 W/m·K, superior to aluminum. This allows more efficient heat dissipation and reduces LED operating temperature by up to 5°C. Greater thermal balance, longer lifespan.

Our natural copper finishes are treated to accompany aging in a controlled way. We offer two options: one that activates the patina between 6 and 10 months, and another that delays it up to 5 years.

8 years warranty on copper and bronze.

Noble materials = Timeless beauty
