Dunbarton is constantly innovating door designs. The furnace doors are perfect for laundry, furnace, or air handler (HVAC) closet doors. These doors are side-hinged full louvered doors constructed with 25 gauge cold rolled steel or A40 galvannealed Steel. Available in standard colors of Bright White, Ivory or Prime for field painting and are easy to install.
The Furnace I Utility doors are 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. No exposed edges of the steel or hardware cutouts compared to our competition. Dunbarton also offers an option of A40 galvannealed steel that combined with our factory paint system gives maximum rust protection.
The factory-applied paint finish meets or exceeds the 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.
Painted finishes also passed a 700-hour humidity test per ASTM–D1735-87.
