The high mechanical resistance values of CorTen steel allow for small sections and therefore with a lower visual impact and higher indoor brightness while, at the same time, making it possible to realize large and heavy doors and windows with excellent performance. Corten steel is a high-resistance self-passivation alloy containing copper, chrome and phosphorus, characterized by a high resistance to corrosion and to tensile yield; these allows are self-protective through the formation of a superficial coating that prevents the progressive extending of the corrosion process. Brombal, thanks their innovative and technological vocation, was the fist one to use this material for doors and windows, producing profiles with physical and aesthetic features particularly appreciated in the architectural world.
The large rolls of CorTen steel are cut to the required width and rolled to the specific profile section. Upon exposure to air, the patina process begins which creates a protective layer of rust over the surface. Left untreated, the rust will create an ever changing appearance. A surface wax treatment can be applied which will stop the continued rusting and will provide a protective barrier against the elements.
- Thermally broken.
- Only manufacturer to offer a window and door system utilizing CorTen.
- Durable and resistant to environmental elements.
- 100% recycled materials.
- Perfect choice for highly corrosive environments.
- Unique finish not replicated by any other material.
CorTen steel has a unique distinctive appearance. The intense richness of its finish bestows a warm, natural, yet at the same time extremely elegant look. Its attractive appearance is a result of an oxidation process which forms a protective patina that remains unchanged over the years. A hand applied wax treatment can be administered to achieve a smooth finish.
