Alabama has hot, humid summers, with coastal and inland conditions that differ. A state name alone does not describe the exposure of a particular fence. Tell us whether the project is near saltwater, beside irrigated ground or in an inland commercial setting.
Use that site information to ask the project specifier about the required coating system. Galvanized and color-coated fabric are separate choices; the color of a component does not establish its coating specification or expected service life. Coordinate the proposed fabric with posts, rails, gates and fittings before accepting a material schedule.
