Brombal Bronze

About Bronze

The warm, lustrous color typical of old Bronze and its unique aesthetic qualities make this the ideal choice for restoration of old buildings, where it blends perfectly with the architectural design. Bronze is particularly resistant to atmospheric elements making it the perfect choice for coastal applications.

Bronze lends itself perfectly to projects from historic renovations to modern architectural designs. Over time the natural oxidation process creates a patina that will transform to an attractive rich dark brown color creating an almost living and every changing finish.

The Material

Utilizing the highest quality bronze in the fenestration industry, our products are made from 67% copper and 33% Zinc. This ratio is what allows the alloy to acquire a beautiful patina typical of old bronze. Bronze is one of the first materials used to forge tools and weapons, during the renaissance period bronze was used to make doors in some of the most famous buildings like St Peters Basilica, the Pantheon, and Baptistery of St Johns. Bronze lends itself perfectly to projects from historic renovations to modern architectural designs

Transformation Process

After the coil stock is cut and rolled into the frame sections it undergoes a heat treatment. This prevents the sections from potential cracking as it relieves the stress applied during the rolling process. The resulting product is the highest quality bronze available in the fenestration industry
