What happens here
Wrap the pressure-treated wooden posts with a protective barrier (e.g., blue film) before installing decorative post wraps. This is crucial because chemicals in pressure-treated lumber can corrode aluminum or other metal components over time. Finally, install the decorative post wraps and re-install any remaining siding panels to complete the exterior finishing of the patio roof structure.
Goal: Complete exterior finishing of posts and siding, protecting against corrosion.
