When a designer begins working through the glazing and fenestration options, they will often find the choices lacking. These are typically limited to standard aluminum frames. Zahner provides custom mullion and transom design development and fabrication, expanding the designer's palette by as far as the imagination will take them.

Unique mullion and transom systems can benefit an otherwise standard design by adding something intriguing to the vertical and horizontal supports. From prestige metal alloys to ornate tracery and historic metalwork, customizing these component covers can transform a design from a standard architectural feature into something fantastic and one-of-a-kind.

These mullion systems can be retrofitted onto existing aluminum mullion systems, or customized onto uniquely shaped extruded aluminum forms developed by Zahner.
