Quanex Building Products’ standard rectangular and contoured shaped muntin bars provide builders and owners with a classic grid system for double- or triple-glazed insulating glass windows and doors.  Our muntins are finished using a non-outgassing paint and can be used in classic rectangular windows as well as in unique circular and other window shapes and designs.

We have tooling in-house for the most common shapes in the window and door industry, including five rectangular shapes and three contoured profiles.

We employ a total quality management system that includes CAD-designed profiles, high-quality steel carbide tooling and precision non-contact measurements. Additionally, our manufacturing processes are linked wherever possible to drive down labor costs and improve efficiencies. These initiatives have resulted in best-in-class quality, lead times and overall service.
