Profile forming

The process of creating metal windows and doors involves cutting strips from large coils of steel, cor-ten, stainless, or brass, which are inspected for flaws and rejected if any are found. The strips are then pushed through rolls that progressively shape the metal strip into its final shape and work-harden the material, increasing its strength.

The two metal halves are combined firmly together with a fiberglass strengthened extrusion, which is then coated with a high-density polyurethane resin, injected, and set under extreme pressure. This forms the Thermally Broken element, which significantly reduces conductivity and creates a slender and efficient line of steel and architectural bronze windows and doors.
