> Degreasing Stage: Aluminum profiles undergo cleaning to remove oil, dust, and contaminants. Multiple water rinses ensure complete removal of cleaning agents.
> Chromium-free Treatment: Profiles pass through special chromium-free solutions for environmental protection. Water rinses remove residual chemicals before drying.
> Powder Coating: Automatic electrostatic powder coating applies three layers for durability. Process includes pre-heating, coating application, and curing in specialized ovens.
> Wood Grain Transfer: Optional wood grain paper application creates natural textures. High-temperature vacuum process ensures permanent adhesion and realistic appearance.
> Quality Control: Color matching and surface inspection verify coating consistency. Final protective film application prevents damage during handling and installation.
