Polyamide Thermal Barrier Advancement & Surface Durability
Historical concerns regarding the thermal conductivity of aluminum frames have been completely resolved through multi-chamber thermal breaks. By inserting high-density PA66 GF25 (25% glass fiber reinforced polyamide) insulation bars into extruded aluminum profiles, structural warmth is retained even in sub-zero climates.
Furthermore, advanced surface treatment engineering—such as AkzoNobel PVDF fluorocarbon electrostatic spraying and 25-micron anodic oxidation coatings—guarantees that exterior aluminum pivot doors withstand extreme UV radiation, salt-spray corrosion in coastal regions, and industrial atmospheric pollutants for over 30 years without fading or chalking.
