PROCESSES
FINISHES ENGINEERED TO LAST
Every anodizing job starts with the right process for the part — and the right line for its size. NIA runs two dedicated lines capable of handling parts from small precision components to architectural extrusions up to 27.5 feet long, across four core processes.
SULFURIC ANODIZING
A FINISH THAT GOES BEYOND THE SURFACE
Type II and Type III anodizing for corrosion resistance, surface hardness, and color. Available for both long-length architectural work and precision machined components.
- Large aluminum components
- Long extrusions
- Architectural parts
- High-volume production runs
ELECTROLYTIC ANODIZING
A FINISH THAT GOES BEYOND THE SURFACE
2-step electrolytic anodizing for architectural applications — AAMA 611-compliant finishes with consistent, long-lasting color on extrusions up to 27.5 feet.
- Large aluminum components
- Long extrusions
- Architectural parts
- High-volume production runs
MORE THAN A FINISH
PTFE
A FINISH THAT GOES BEYOND THE SURFACE
Dry-film lubrication applied over an anodized surface for parts requiring reduced friction, non-stick properties, or added corrosion resistance.
CLEAR
BLACK
BRONZE
COLORS
A FINISH THAT GOES BEYOND THE SURFACE
NIA specializes in the finishes architects and manufacturers ask for most: clear, black, and bronze. Need something outside these three? We also offer custom color matching to meet specific project or brand requirements.
