Prefinished Hollow Metal Doors and Frames are available in eight standard colors. “Custom Color” selections can easily be matched to ensure the finished product will meet the requirements of the designer. Dunbarton hollow metal is finished in a state-of-the-art paint conveyor line with electrostatically applied, baked-on enamel. This ensures complete coverage of the frame with a “best in the industry” paint finish. Dunbarton’s hollow metal comes standard with A40 zinc-coated galvannealed steel that combined with our factory paint system give maximum rust protection.
The Dunbarton factory-applied paint finish meets or exceeds 500 hour salt spray test per ASTM–B117-97. This is four times the requirement of hollow metal frames per SDI (Steel Door Institute) of 125 hours. Dunbarton painted finishes also passed a 700 hour humidity test per ASTM–D1735-87.
