Anodizing keeps the metal's metallic look and suits indoor furniture; powder coating gives a thicker, colorful, more scratch-resistant skin for outdoor or high-wear pieces.

Anodized or powder coated — which finish is better for furniture aluminum profiles?
Anodizing suits clean indoor metal looks; powder coating wins outdoors and anywhere that needs thicker color protection.
How do the two finishes differ in scratch/wear resistance and corrosion resistance?
Powder coating forms a 60-90 µm polymer layer, which is thicker and more scratch-resistant than the 10-15 µm anodic film I apply. For tabletops, chair frames, or anything rubbed daily, powder usually wears better. Anodizing converts the aluminum surface itself into a hard oxide, so it never flakes or chips and resists corrosion well indoors. Anodized surfaces show fine scratches more visibly; powder hides them but can chip under sharp impact.
Which finish should I pick for outdoor or humid environments (patio, bathroom, coastal)?
For outdoor, coastal, or humid use I steer clients to powder coating — its thicker film seals the metal and stands up to UV and moisture, and I can recommend a weather-resistant topcoat for extra protection. Anodizing can still work outdoors, but in a seaside or bathroom setting the thinner oxide film needs a thicker specification and regular care. Tell me where the furniture will live, and I will match the finish and thickness to that environment.
What coating/anodizing thickness can you achieve, and how many salt spray hours does it pass?
I hold anodizing at 10-15 µm and powder coating at 60-90 µm, checked with film-thickness gauges on every batch. On salt spray: I do not advertise a fixed hour rating, because corrosion resistance depends on the full coating system, pretreatment, and environment. I follow applicable standards and can arrange salt-spray testing to your target (e.g., ASTM B117) on request, so the number you get is measured, not assumed.
