For Interior & Residential Designers

Steel doors & windows that fit the design.

When you're specifying doors and windows, the details matter — proportions, sightlines, glass, divided lites, hardware, finish, and how the opening connects to the rest of the space.

BlackFramed works with interior designers and residential design teams to develop custom steel doors and windows around the project.

Steel doors & windows

From the first concept to the final detail.

Whether you're working on a new build, renovation, or interior remodel, we can help with the product details that need to be worked out before fabrication.

  1. 01

    Choose the profile system

    Compare European steel systems based on sightlines, thermal requirements, configuration, and application.

  2. 02

    Develop the opening

    Custom dimensions, divided lites, glass, swing, sliding, pivot, and other configurations.

  3. 03

    Coordinate the details

    Finish, hardware, glass, and other selections can be specified around the overall design.

  4. 04

    Review shop drawings

    Shop drawings help confirm dimensions, divisions, and details before fabrication.

European systems for different applications

We work with established European profile systems from Ottostumm, Secco Sistemi, Forster, Welser, and our BF Slim 20 interior system. Each has different characteristics, so the best option depends on where the opening is being used and what the project requires.
