Q1: What's the difference between mill finish and brushed aluminum?
Mill finish retains the raw factory surface. Brushed finish has uniform linear scratches from polishing. Both accept anodizing or painting. Mill finish costs 15-20% less for industrial use. Brushed surfaces better hide everyday scratches.
Q2: Why anodize aluminum?
Anodizing thickens natural corrosion resistance. It allows permanent coloring via dye absorption. Hard anodizing boosts wear resistance. Creates electrical insulation layer. Simplifies cleaning with smooth surface.
Q3: How does powder coating work?
Electrostatic spray attracts powder to metal. Baking at 200°C bonds it into smooth film. Available in 5,000+ RAL colors. Resists chipping better than liquid paint. Eco-friendly with near-zero VOC emissions.
Q4: What is "anodizing sealing"?
Boiling water closes porous oxide layer. Nickel acetate sealing enhances stain resistance. Cold sealing speeds up production. Sealing prevents dye bleeding over time. Doubles corrosion protection lifespan.
Q5: Why choose wood-grain aluminum?
Film lamination creates realistic wood patterns. More durable than real wood outdoors. Doesn't rot, warp, or attract insects. Easy to clean with damp cloth. Costs less than teak or cedar cladding.
