GEIGHER Delta Frames are designed for large areas such as hotels, restaurants, and huge offices. Delta Double Furring and Single Furring are especially designed with a side recess to provide a more stable and sturdy frame. Delta Wall Angles have ends that are bended for safety against cut and for better handling. Combined with the extra corrosion and moisture protection of the gold resin layer, this makes Delta Frames the GOLD standard in ceiling systems.
