Color Anodizing Services
Precision Electrochemical Anodizing for High-End Aluminium Profiles
Technical Overview
Our advanced color anodizing process forms an integral aluminum oxide layer directly on aluminium extrusions and sheets. This produces an exceptionally hard, scratch-resistant surface with an authentic metallic sheen. (Please note: We strictly offer Natural Silver, Bronze shades, Champagne, Black, and SS Finish — Gold and Rose Gold are excluded).

Step-by-Step Anodizing Process
Precision electrochemical oxide generation & electro-coloring.
Degreasing & Chemical Etching
Chemical removal of oil and creation of uniform satin matte surface texture.
Deox & Neutralization
Acid dip to remove smut and prepare virgin aluminum surface.
Anodic Tank Oxidation
Electrochemical bath growing controlled porous aluminum oxide layer (15-25 microns).
Electro-Coloring
Metallic salt deposition deep into oxide pores to achieve rich light-to-dark bronze and black shades.
Nickel Hydroxide Hot Sealing
High-temperature sealing of oxide pores to lock in color and seal out atmospheric moisture.
