Aluminium vs Wood Pergola: Which Is Better?

Aluminium 6063-T6 is rust-free, rot-proof and maintenance-free for 25+ years. Wood requires annual treatment. Aluminium weighs half as much. Initial cost is 20-30% higher but 10-year total cost is lower.

Modern design + low maintenance + motorised louvres: aluminium. Rustic look + low upfront budget: wood. However, wood cannot match aluminium's louvre integration and waterproofing.
