Dark metal panel surface with moderate wear and aging. Features horizontal plating with visible seams, rivets, rust patches, and subtle dirt buildup. Surface includes faded areas, streaks, and edge grime, giving it a used but functional look. Suitable for sci-fi environments, military assets, post-apocalyptic settings, or industrial scenes. This is the mid-stage variation in a damage series—more weathered than the clean version, but not yet fully decayed. Perfect for storytelling through material aging and environment detail.
