POLYESTER POWDER-COATED PAINT FINISH FOR THE FRAME
The quality and durability of the De Nardi overhead doors are guaranteed thanks to the stove-enamelled polyester powder paint finish. The painting is carried out in the up-to date automated plant, where it goes through an efficient production cycle: phosphating-cleaning/degreasing in a tunnel, double rinsing-kiln drying at 130°-polyester powder spraying in robotised or manual booth (average thickness 40 micron)-drying in oven at 200°C.
