Dimak fire doors are coated in a modern robotic electrostatic powder coating line. While standard color is RAL 9002, any requested RAL color can be applied. Fire door frame and leaf may be in different RAL colors as well as inner and outer of leaf. For a better powder penetration, galvanized steel which has a special surface is used. Due to galvanized steel usage in production of leaves and frames, fire rated steel doors have high corrosion resistance. Fire doors are coated with polyester electrostatic powder which is appropriate for both outdoor and indoor usage providing UV resistance.
