Bi-Fold Doors


Grabill’s luxury exterior folding door systems accommodate multiple panels for large expanses, creating a truly seamless transition between indoor and outdoor spaces. When closed, these precision engineered doors create a formidable barrier against the elements. Door panel configurations are as specified with in-swing or out-swing operation. Folding doors are also available in all-wood and aluminum-clad.

All of our bronze clad products feature Grabill custom profiles made with heavy gauge extruded metal that will last for generations and naturally oxidize over time without degrading the metal. Grabill custom patina and finish applications achieve various levels of Bronze Aging and Antiquing without the wait.

The Grabill contemporary aluminum clad product line has the best of both worlds: the strength and weather resistance of Grabill custom profiles in extruded aluminum to the exterior, and the warmth of handcrafted wood to the interior. Our heavy duty extruded aluminum cladding contains over 90% recycled material, is locally produced. Painted Kynar 70 finish offers 10 year unconditional warranty and can be color matched to virtually any color. Anodizing and powder coated finishes are also available.
