Bifold Doors

Brombal bifold doors are excellent in areas where unobstructed views are required. Utilizing our thermally broken system, you get the energy performance benefits of a thermal break and narrow sightlines, which are much smaller than aluminum and you can span wider and taller openings due to the structural stability of the steel sections. Units can hinge from the inside, outside, or in the center to take maximum advantage of the available space. Each unit is designed specifically for the opening.

Custom hardware is utilized to create either a flush sill or step as required. The first leaf can operate independently with a multipoint lock to serve as the primary door. The adjacent leaf can offer a French door application. Units can slide in one direction or can part in the middle. Talk to us about your design and we will work with you to accomplish your goals.

Bifold Door Products

Brombal bifold doors are a great option to consider instead of French doors or sliding doors when a partially open or a wide, completely open and uninterrupted wall is desired. The advantages of bifold doors are strength and longevity of a steel product with a thermal break. Some features of note for this series:

  • Individually operable swinging doors can be incorporated, allowing the first leaf to open as a regular door or the first two to open as French doors.
  • Brombal bifold doors are available in a thermally broken product, with accompanying great insulating capabilities.
  • A wide variety of hardware options are available, including multipoint locking systems.
  • These doors are available in a wide range of materials including galvanized powder coated steel, stainless steel, Corten steel, and brass for a bronze aesthetic.
  • A variety of glazing options are available, including argon filled glass and several different glass coatings.
  • The Brombal bifold door system offers a great deal of design flexibility for architects and designers. Choose from a variety of metal materials, glazing materials, and hardware options.
    • The glazing is installed on-site, so there is great flexibility with regard to glazing and door material combinations.
    • The number of panels can be chosen to suit any particular configuration and opening size.
    • Brombal bifold doors can be designed to meet at a corner without a corner post, providing an unobstructed opening.


All of our Brombal bifold doors are made specifically for each opening. The height and width of each panel is determined by the style and layout of the unit. Please contact us to discuss the details of your project.
