Engineered finish, baked-on
A primer base coat is baked on first, followed by a polyester topcoat with a textured additive — also baked on — giving every cover the grain and warmth of real timber. No staining, no repainting, no rot.
Since 2001 Castle Vinyl & Aluminum Distribution has supplied baked-finish aluminum patio covers to San Diego County builders, developers, and homeowners who want the look of wood with none of the maintenance.
